The Osprey Ariel 65 ($370) is a meat-and-potatoes backpacking pack with all the bells and whistles you actually need. It’s heavy, yes—but that weight goes toward plush padding, a burly suspension, and a feature-rich design that makes carrying 40+ pounds feel surprisingly smooth. If you’re looking for a breathable, minimalist pack for summer fastpacking, this isn’t it. But for long, gear-laden trips where comfort, durability, and organization matter more than saving ounces, the Ariel is a reliable, workhorse option at a competitive price.

Osprey Ariel 65
For this season's top models, see our guide to the Best Backpacking Backpacks.
The Osprey Ariel 65 (men’s Aether 65) is one of the most comfortable packs I’ve ever used for hauling heavy loads. I wore it on a long, steep push into the Enchantments—including about 5,000 feet of gain over snow, loose sand, and rocky, off-camber terrain—with 30 pounds in the pack, and it handled the climb without a hitch. The shoulder straps and hipbelt are lined with thick, dense foam that felt both cushy and supportive. I didn’t get any pressure points, and the pack stayed balanced with minimal shifting.
The Osprey Ariel 65 is rated to carry an impressive 60 pounds, but your mileage will vary based on strength, fitness, and other factors. Based on my experience, I wouldn’t hesitate to load it up past 40 pounds. One of my teammates mentioned that while the Ariel doesn’t “hug” your body quite like the Osprey Aura AG, it has noticeably more supportive hipbelt padding, and I’d agree with that. My only gripe is the breathability—there’s some mesh on the backpanel, but it doesn’t extend across the whole thing, so it got a bit warm in sunny stretches. Still, if I know I’m heading out with a heavier load or rough terrain ahead, this is one of the first backpacking packs I’d reach for.
The Osprey Ariel 65 has more than enough storage for a multiday trip, and overall, I found the layout super intuitive. There are two zippered pockets on the lid—the smaller one houses the included rain cover—and two generously sized hipbelt pockets that easily fit my iPhone 15 along with snacks or a headlamp. The two side water bottle pockets are stretchy and accessible from both the top and side, which makes it easy to grab a bottle without taking the backpack off. I also liked the big front stash pocket for dumping a wet shell or layers on the go.
Access to the main compartment is great: there’s a traditional top opening, a large U-zip on the front panel, and a dedicated sleeping bag compartment at the bottom. I was even able to fit my sleeping bag and pad down there, which was a nice surprise. There’s a hydration sleeve inside with hose ports on either side, and loops on the shoulder straps to guide the hose. That said, I did find myself wishing for a bit more zippered storage along the front. A backpacking pack like Gregory’s Deva 60, for example, has better separation for organizing kid gear or bulkier loads. The Ariel keeps it functional and straightforward, but if you’re someone who likes every item to have its place, you might feel a little limited.
At 4 pounds 14.3 ounces, the Osprey Ariel 65 isn’t trying to be fast or minimal—it’s a pack designed for comfort, structure, and load-hauling capability. Unless you're planning to fully take advantage of its carrying capacity, the weight can feel like overkill. I didn’t mind it on my trip into the Enchantments, where I was carrying a decent load over technical terrain, but if I’d packed lighter, I would’ve wanted something sleeker. For comparison, the Osprey Aura AG 65 clocks in at 4 pounds 9.5 ounces, the Gregory Jade 63 at 4 pounds 3.2 ounces, and the ultralight-minded Osprey Eja 58 is just 2 pounds 13.2 ounces. But if you’re planning to carry 40+ pounds regularly, the extra weight is totally justified.
The Osprey Ariel 65 is one of the most durable backpacking packs I’ve used that isn’t made with ultralight Dyneema. With 420-denier nylon across the entire pack body, it’s built to handle rough terrain, abrasion, and long-haul wear and tear. I didn’t worry about scraping it on rocks, setting it down on dirt, or stuffing it full for a technical approach. That kind of peace of mind is exactly what I want in a pack designed for serious, gear-heavy trips.
Compared to other packs in this category, the Ariel’s construction stands out. The Gregory Deva 60 uses a mix of 210D and 420D nylon with a 630D bottom, while the Osprey Aura AG 65 drops to 210D on the body and reserves 500D just for the base. Even the Gregory Jade 63, which has a 400D polyester body and 420D nylon bottom, doesn’t quite match the Ariel’s overall ruggedness. Sure, the burly nylon build adds weight—but if you’re heading out for extended trips where your gear needs to survive the elements, it’s a tradeoff that feels well worth it.
The Osprey Ariel 65 comes with a built-in rain cover, which is a big win in my book, especially for a backpacking backpack in this size and price range. On its own, the nylon shell does a decent job fending off light drizzles, but like most traditional fabrics, it’ll start to soak through in sustained rain without the cover. Thus, the rain cover offers peace of mind knowing I have coverage ready to go if and when the weather turns. This is an advantage compared to the competition: the Gregory Deva and Jade don’t come with a rain cover, while the Osprey Aura AG does. If you’re hiking in unpredictable conditions or don’t want to shell out extra for a separate cover, it’s a thoughtful inclusion that adds real value.

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.
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.
The Osprey Ariel 65 comes in two base sizes for women—XS/S and M/L—and also includes Extended Fit versions in both ranges. The torso length adjusts using Osprey’s slider system, which I’ve always found to be one of the easiest and most intuitive to operate. The hipbelt is also adjustable, and in theory, the whole system should make dialing in the right fit pretty straightforward.
However, I ran into some trouble finding the right size. My torso measures around 17 inches, and according to Osprey’s sizing chart, I could’ve gone either way. I chose the XS/S because of my overall smaller frame, but I ended up regretting it. Even after adjusting the backpanel and shoulder straps, the chest strap sat too high, and the pack didn’t rest comfortably on my hips. The hipbelt had about 12 inches of excess webbing once cinched, which felt like a mismatch for how the rest of the pack was sitting. With better pre-purchase guidance or more specific size increments, I probably could’ve avoided this issue—but as is, I struggled to get the fit dialed in the way I needed.
Gregory Deva 60 ($370): A Near-Carbon Copy
Like the Ariel, the Gregory Deva 60 (men's Baltoro) is a heavy backpacking pack for heavy loads. Its specs are near-identical—it’s just 1 ounce heavier in a size medium—although it has two additional exterior pockets while matching the Ariel with a sleeping bag compartment, water reservoir, and large hipbelt pockets. With its metal perimeter frame, fiberglass stay, and sturdier padding, we found that the burlier Deva is even more dialed than the Ariel for carrying heavy loads. However, the Deva sports less durable material overall, with mostly 210-denier fabric (but its 630D bottom is thicker than the Aether’s). The Deva comes in three sizes, to the Ariel’s two, but not in extended fit versions, and its torso and hipbelt are slightly more difficult to adjust. For more, read our review of the men's Gregory Baltoro 75.
Osprey Aura AG 65 ($370): Comfort Comes First
Compared to the burlier Ariel, the Osprey Aura AG 65 (men's Atmos AG) prioritizes ventilation, comfort, and user-friendly features for traditional backpacking loads. Its standout suspended mesh backpanel offers unmatched airflow, and the seamless hipbelt connection provides excellent stability and support up to around 40–45 pounds. You also get convenience-focused touches like dual zippered front pockets and side zip access—things the Ariel skips in favor of simplicity and durability. While it’s not built for hauling 60-pound loads or heavy bushwhacking, the Aura shines on multi-day trips where balanced carry and thoughtful organization matter most. For more, read our men's Osprey Atmos AG 65 review.
Osprey Ariel Pro 75 ($430): The Souped-Up Version
First, let’s address the pack-shaped elephant in the room: The Osprey Ariel Pro 75 is expensive. It justifies (perhaps) its cost by providing more storage volume than the Aether, more durable material, and an upgraded suspension, all without incurring a weight penalty (at 4 lb. 12 oz. it actually weighs less). Weight savings come mostly from its 210-denier nylon fabric, which incorporates 21% ultra-high-molecular-weight polyethylene fibers—the same ones found in Dyneema—to grant high tear strength without tipping the scales. The Pro also jettisons the Ariel’s side and dorsal pockets for a streamlined design, although its hipbelt pockets are larger (and removable). It has a 4-millimeter frame to better distribute heavy loads compared to the Ariel’s 3.5-millimeter version. If you want to increase your carrying capacity and seek a pack that’s durable enough for mountaineering and other intense adventures, this pack might be worth the outlay.
The women's Ariel is Osprey’s long-standing, flagship workhorse pack designed to provide a stable, comfortable carry for long hikes and large loads. But its heavy weight and less-than-stellar backpanel breathability may dissuade some buyers.

With its load-eating suspension, supportive padding, and durable materials, the Deva (men's Baltoro) has become synonymous with “heavy duty” over the years. However, it’s too overbuilt and expensive for most “normal” backpacking trips.

Osprey's “classic” backpacking pack, the well-rounded Aura prioritizes comfort and user-friendliness, highlighted by a trampoline-style mesh backpanel and copious pockets. The weight and steep price are hard to ignore, though.

The Osprey Ariel 65 is a classic load-hauler that’s ideal for backpackers who prioritize comfort, support, and durability over cutting weight. If you’re carrying 40+ pounds on multi-day or gear-heavy trips, the Ariel’s robust suspension and dense, supportive padding make it a dependable choice. It’s heavier than most backpacking packs—and less breathable too—but it makes up for that with excellent organization, a built-in rain cover, and seriously tough construction. If you lean ultralight or hike mostly in hot conditions, you’ll probably be happier with a more minimalist, better-ventilated pack. But for the price, the Ariel offers a ton of value and function for the right kind of hiker: someone who wants their pack to carry the weight, not cut corners.
