Arc'teryx Beta SL
For this season's top shells, see our guide to the Best Rain Jackets.
I tested the Arc’teryx Beta SL during spring in New Zealand, a notoriously wet season. Because it was the lightest and thinnest waterproof shell I’d ever worn, I was pleasantly surprised to find that it kept me perfectly dry in wet, windy weather that sent raindrops flying sideways into me. I threw the Beta SL on to protect myself from mist, downpours, and alpine wind gusts from Aoraki/Mt. Cook National Park on the South Island to Tongariro National Park on the North Island; I even slept with it covering my face while I cowboy camped on a drizzly night. Never once did rain seep through the jacket to dampen my layers underneath.
Credit for the Beta SL’s impenetrable quality goes to its 3-layer Gore-Tex membrane, which is made from expanded polyethylene (ePE) and features a soft, knit backer. The face fabric is also coated with PFAS-free durable water repellent (DWR), which combines with the membrane to shield wearers from the elements. The Arc'teryx Beta SL is also fantastically windproof; it was a welcome addition when I was being pummeled by gusty 40-mph wind gusts on top of the Tararuas, a mountain range on the North Island notorious for its turbulent conditions. Hook-and-loop closures on the wrists and an internal drawcord for the hem further batten down the jacket. If rain or wind is in the forecast, I couldn’t ask for a better insurance policy than this shell.
Like most 3-layer Gore-Tex rain jackets, the Beta SL’s nylon face fabric is stiff and crinkly, and it isn’t very flexible. However, I found it offered plenty of freedom of movement, without any constriction in the shoulders or arms—a plus when I was crawling over grass tussocks in the face of gale-force winds in New Zealand (note: I did size up for extra room). Additionally, the Gore-Tex material features a relatively soft knit backer on the inside that offsets the otherwise papery feel of its shell fabric.
When I fully zipped up the Beta SL, I found that I could cinch down the hood to fit over my head without it resting against my face. Because of its light weight, this shell is obviously not bulky, either. Overall, I found the Beta SL quite comfortable to wear over other layers and under backpacks.
I would describe myself as someone who doesn’t sweat easily, especially back home in Colorado's dry climate. In New Zealand, which is a much more humid region, I found myself sweating more than usual as I trekked along challenging backpacking routes while wearing the Beta SL. This shell features long underarm zippers for ventilation, and its 3-layer Gore-Tex is well-known for moderate breathability. Still, the conditions would've tested any jacket: With temps in the high 50s and moderately humid conditions, I found myself getting too clammy as I pushed uphill—no switchbacks in sight—while wearing a very light merino shirt underneath.
I never overheated while I hiked downhill, though, and I would say that the Beta SL was more breathable than my previous Marmot shell (which lacked pit zips). Additionally, it easily outperforms 2.5-layer shells, which are far more prone to getting clammy and sticking to your skin (read more about 2.5 vs 3L shells). Overall, no waterproof shell truly stands out in breathability, but the Beta SL lands in an above-average position.
At only 10.6 ounces, the women’s Beta SL’s weight places it in a prime position within the rain shell category. Many lighter shells don’t have 3-layer constructions and are thus less breathable or made from far less durable materials. On the other hand, heavier models may feature sturdier zippers, fabrics, or more pockets, but their advantages in terms of waterproofing and breathability are minimal, if any. For comparison, the Outdoor Research Helium Rain weighs 6.3 ounces but has a much thinner material (30D) that's noticeably clammier and more fragile. The Patagonia Torrentshell 3L weighs 12.4 ounces but is less breathable and doesn’t pack down nearly as well.
On my treks, I packed this jacket by zipping it up, folding the sleeves away, and rolling the whole bundle into the hood. When packed this way, the Beta SL is slightly smaller than my iPad in length, while compressing to about 2.5 inches in height. With that level of packability, this shell is an easy choice to take on anything from a gear-intensive backpacking trip to a casual day hike.
It’s difficult to estimate “mileage” on a shell as you would with boots or a backpack, but I’ve hiked more than 300 miles across New Zealand, Colorado, and California while testing the Arc'teryx Beta SL, and I haven’t inflicted any noticeable damage. While this shell may seem thin and is definitely light, its 40-by-70-denier (D) nylon face fabric boasts above-average thickness and strength (many lightweight shells are 40D or less). New Zealand’s terrain is well-known for trashing gear quickly, but although I wore the Beta SL through moderate bush—pushing past branches and shrubs—it never suffered a scratch. (Granted, I have also been careful while wearing this shell.)
The Beta SL’s zippers are all made by YKK, and they operate smoothly. There are toggles on the hood to cinch it when you’re not wearing a helmet. They feel like they’re of good quality and design, and I’m not worried about them breaking or falling off. Thankfully, given this shell’s steep price tag, it looks like it will accompany me on many future treks.

Longevity
Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.
PFAS-Free DWR
Durable water-repellent (DWR) finishes can contain PFAS (per- and polyfluoroalkyl substances). These highly persistent “forever chemicals” are used in outdoor gear for their strong resistance to water, oil, and heat, but are linked to environmental contamination and a range of health concerns. A green check mark indicates the product uses a PFAS-free DWR, while a red X means the DWR contains PFAS.
PFAS-Free Waterproof Membrane
The membranes used in waterproof products such as rain jackets, ski jackets, and shoes can contain PFAS (per- and polyfluoroalkyl substances). These highly persistent “forever chemicals” are valued for their resistance to water, oil, and heat, but are linked to environmental contamination and a range of health concerns. A green check mark indicates the product’s waterproof membrane is PFAS-free, while a red X means it contains PFAS.
Recycled Materials
Recycled materials are prevalent in outdoor gear, with nylon, polyester, wool, and down among the most common, but the composition varies widely. A green check mark indicates the product is made with a substantial amount of recycled materials (100% recycled or the core fabric that makes up most of the product is recycled), a yellow check means it contains a moderate to small amount of recycled materials, while a red X means there are no recycled materials in the product.
Bluesign Approved
Bluesign Technologies, based in Switzerland, operates a third-party textile management system that ensures materials are manufactured to strict environmental, chemical, and worker safety standards. A green check mark indicates a product is either a Bluesign Product (contains at least 90% Bluesign-approved fabrics and 20-30% Bluesign-approved accessories) or features a significant amount of Bluesign-approved materials. A yellow check mark means it uses some Bluesign-approved materials but less than the aforementioned category, and a red X means there are no Bluesign-approved materials in the product.
Responsible Manufacturing
This criterion evaluates a brand’s commitment to fair wages, safe working conditions, and reducing environmental impact through certifications and programs like Fair Trade Certified, Fair Wear Foundation, Worldwide Responsible Accredited Production (WRAP), and the Fair Labor Association, while also recognizing brands that manufacture primarily in the U.S. or Europe under strict labor and environmental regulations. A green check mark indicates a brand meets our responsible manufacturing criteria, while a red X means it does not.
Recycled and/or Reduced Packaging
Packaging can add significant waste to outdoor gear purchases, so many brands work to reduce its impact by using recycled materials, incorporating Forest Stewardship Council-certified paper products, and minimizing plastic and paper use. A green check mark indicates a brand uses recycled or reduced materials across all of its packaging, a yellow check indicates moderate or limited use of recycled or reduced packaging, and a red X indicates the brand does not make either of these efforts.
Repair Services
Repair services extend the lifespan of outdoor gear and reduce overall consumption, though programs vary widely. Some brands offer comprehensive repairs for a range of issues, while others provide limited or no repair support. A green check mark indicates a robust repair program, a yellow check mark indicates limited repair services, and a red X indicates the brand does not offer repair services.
Resale and/or Recycling Services
Resale and recycling programs help keep outdoor gear in circulation longer and out of landfills, ranging from trade-in resale platforms that offer store credit to take-back initiatives that recycle products at the end of their usable life. A green check mark indicates a brand offers both resale and recycling programs, a yellow check mark indicates it offers one or the two, and a red X indicates it offers neither.
Carbon Footprint Tracking
This criterion evaluates whether a brand measures, reports, and works to reduce its greenhouse gas emissions using established frameworks such as the Higg Index, Greenhouse Gas Protocol, or The Change Climate Project. A green check mark indicates a brand publicly reports greenhouse gas emissions data, sets clearly defined reduction targets, and uses established tracking frameworks such as Higg or The Change Climate Project. A yellow check mark indicates the brand tracks emissions and outlines reduction goals but provides limited data, lacks science-based verification, or does not clearly report progress. A red X indicates the brand does not appear to track greenhouse gas emissions or provides so little information that its efforts cannot be verified.
Annual Impact Report
Annual impact reports provide transparency and accountability by outlining a brand’s sustainability efforts across areas such as material sourcing, greenhouse gas emissions, waste, water use, supply chains, and packaging. A green check mark indicates a brand publishes a detailed, brand-specific impact report that closely aligns with our sustainability criteria and leaves little room for ambiguity. A yellow check indicates a brand provides some relevant sustainability reporting but lacks detail in key areas or is covered only briefly within a parent company report. A red X indicates a brand does not regularly publish an impact report.
Hood
The hood on the Beta SL is designed to fit over a climbing helmet, and I was pleased to find that my size large Black Diamond helmet slid comfortably underneath (it’s not large enough to fit over most ski helmets, however). When I am not wearing a helmet, I use the cinch cord at the back to tighten the hood and prevent it from getting blown off my head. The hood’s short, stiffened brim kept rain from falling onto my face; previously, I’d worn baseball caps under rain shell hoods to keep rain out, which was quite annoying, so this was a helpful feature.
Storage
The Beta SL has three pockets: two hand pockets and an internal chest pocket. Each pocket can fit a phone (I have a Samsung S21), in the case of the hand pockets with plenty of room to spare. The pockets are placed relatively low, which means they’re at a comfortable height for resting your hands but are blocked by a backpack hipbelt. While hiking, I found the placement of the pockets to be cumbersome when attempting to retrieve my phone or other items during wet conditions: The hipbelt limited access to the exterior pockets, while unzipping the jacket to reach the interior pocket caused rain to sneak inside and wind to blow off the hood.
Tester: 5’9”; 33" chest; 27" waist
Size tested: Women’s medium
I initially requested this jacket in a size small, which is the size that typically fits my tall, slender build. However, when I received the Arc'teryx Beta SL, I immediately noted that it was shorter than the Marmot and Black Diamond shells that I’d worn previously, and I exchanged it for a medium. With the small size, the sleeves did not cover my wrists, and the hem hit just at the top of my hipbones. I felt vulnerable with my wrists and behind exposed, given the kind of testing I had slated for it. The medium’s length proved perfect, and the jacket provided the correct amount of space to comfortably wear a base layer and a thin puffy underneath.
I would describe the Beta SL’s fit as regular—not too boxy, but without much of a distinct waistline. The sleeves hit an inch and a half past my wrist in size medium. The jacket’s hem was long enough to securely tuck beneath a backpack hipbelt, and it covered my butt. I found the jacket comfortable to move in, with no restrictions under the arms or at the shoulders. In sum, if you prefer extended coverage and want to leave room for layering, we recommend sizing up, especially if you’re typically on the fence between sizes.
Black Diamond Highline Stretch ($529): Save a Benjamin, Lose Refinement
Black Diamond’s take on the lightweight hardshell is the Highline Stretch. It’s slightly heavier and less packable than the Beta SL, and it also has a slightly thinner shell fabric (40D vs. the Beta SL’s 40D x 70D). The most notable difference lies in the overall feel of the Highline, which features stretchy face fabric compared with the Beta SL’s more classic, stiff 3-layer Gore-Tex construction. We have yet to be let down by the Highline’s BD.dry waterproofing, but the Beta SL’s shell fabric has less of a tendency to wet out in sustained moisture, and it’s hard to beat the performance of Gore-Tex. Finally, the Highline’s fit is noticeably long and roomy, while the Beta SL is a little trimmer. For more, read our review of the Black Diamond Highline.
Arc’teryx Beta ($400): The Everyday Beta
Arc’teryx’s Beta collection is home to several lightweight and versatile shells. While the Beta SL is the high-performance hiking option, the standard Beta slides in as the everyday workhorse. At 10.6 ounces for the women’s version, it matches the weight of the Beta SL but swaps pit zips and a helmet-compatible hood for a thicker, more durable 80-denier fabric. It also features a regular fit compared to the Beta SL’s trimmer silhouette. All told, the Beta is the more affordable, long-lasting, and purpose-built choice for daily frontcountry use, while the Beta SL remains fine-tuned for backcountry performance. For a deeper dive, read our Arc'teryx Beta review.
Patagonia Granite Crest ($289): 3-Layer Benefits With a Lower Price Tag
More and more 3-layer shells are entering the rain jacket market, proving that premium construction doesn’t have to come with a sky-high price tag. A prime example is Patagonia’s Granite Crest, which pairs a 30-denier shell with Patagonia’s H2No Performance Standard membrane and a soft tricot backer—all for $289. Its supple and slightly stretchy build makes it more breathable and comfortable than the Arc’teryx Beta SL, though not quite as durable or bombproof in heavy rain. For mild climates or high-output activities, however, it’s a fantastic value. For more, read our review of the Patagonia Granite Crest.
Arc’teryx’s most approachable hardshell is more durable, breathable, and protective than most 2- and 2.5-layer rain jackets while checking in at a similar weight. However, it’ll cost you $500 and has a rigid, crinkly feel.

With a long and roomy cut, the 3-layer Highline Stretch provides a high degree of coverage and accommodates bulky layers underneath, making it a great option for cold weather and outright bad conditions. The stretchy shell fabric is quiet, supple, and soft against the skin. However, the Highline is overkill for mild temperatures and not everyone will like the oversized fit.

The Beta is Arc’teryx’s premium 3-layer Gore-Tex rain jacket for frontcountry and light backcountry use. The lack of pit zips and a helmet-compatible hood limits its versatility (and $400 is a lot to spend on a fairly simple rain shell), but it's a long-lasting choice with a low weight.

As we mentioned at the beginning of this review, it’s hard to make a recommendation about the Arc'teryx Beta SL without first considering its price. At $500, it’s a significant investment for a rain shell that we’d be hesitant to push into four-season use (its hood isn’t ski helmet-compatible, and it's not cut as long as winter-ready shells). It’s also more jacket than many summer hikers and backpackers will ever need. However, the Beta SL offers protection that’s simply unmatched in the rain jacket category, along with long-lasting durability at a desirable weight. Simply put, it does everything a backcountry hiking rain shell should do with aplomb.
