REI Co-op Flash 22
For this season's top models, see our guide to the Best Hiking Daypacks.
The REI Co-op Flash 22 is a superlight daypack that prioritizes a streamlined build over outright carrying comfort. With no metal frame or even a rigid frame sheet, the only structure comes from a thin layer of foam along the backpanel. The shoulder straps also have minimal padding, and the hipbelt is a lightweight mesh design with wing-like panels that offer more support than basic webbing but still fall short of more substantial designs.
Compared to a more supportive daypack like the Osprey Talon 22, the difference is clear. The REI Co-op Flash 22 can handle a light load well, but once you go over about 10 pounds, the pack starts to sag, and the weight becomes more noticeable on your shoulders. A hydration reservoir can help add some structure if it’s filled, but overall, the pack lacks the rigidity and cushioning to carry heavy or bulky gear comfortably over long distances. For short summer hikes, minimalist summit pushes, or as a travel companion, the Flash 22 does the job. But if your outings regularly require heavier loads or more gear, you’ll likely want a more supportive design.
For a minimalist hiking daypack, the REI Flash 22 packs in a surprising amount of thoughtful storage. While it’s far from feature-rich, REI nailed the essentials: Two stretch side pockets fit standard 1-liter bottles (as long as the main compartment isn’t overstuffed), and a small top lid pocket is handy for stashing quick-access items. One of our favorite details is the vertical zippered pocket along the right shoulder—it's generously sized and runs nearly the full height of the pack, making it a great spot for storing a phone, snacks, or anything you want within reach but safely tucked away.
Inside the main compartment, there’s a hydration sleeve with a simple hook-and-loop strap, plus two small drop-in pockets—helpful for organizing smaller items like snacks or a headlamp. A key clip above one of the pockets adds a nice touch for peace of mind (although it’s not as secure as a key clip inside a zippered compartment).
At just $60, the Flash 22’s organizational layout is a clear strength, and a big reason we prefer it over the even more barebones REI Co-op Flash 18 (which omits the lid and side pockets). That said, it still falls short of more traditional daypacks: The main compartment’s compact, tube-like shape can be limiting, there’s no front stretch pocket for wet layers, and the hipbelt lacks any built-in storage. For minimalist missions, it works great, but it’s not ideal if you prefer quick access to a range of gear on the go.
Tipping the scales at just 14 ounces, the REI Flash 22 is impressively light. Most daypacks with a similar capacity weigh 2 pounds or more—Gregory’s Miko 20 comes in at 2 pounds even, and the popular Osprey Talon 22 is 2 pounds 6.1 ounces—so the Flash 22’s ultralight build really stands out. The frameless design also makes it highly compressible, and you can remove the foam backpanel to make it even more compact for travel or storage.
This level of packability adds a ton of versatility. It’s the kind of daypack you’ll find yourself bringing everywhere: it works as a secondary bag tucked inside a larger travel pack or backpacking setup, and it’s ideal for everything from urban wandering to summit pushes. Simply put, the weight and compressibility are two of the Flash 22’s biggest selling points.
The tradeoff for the Flash 22’s ultralight build is clear: Durability takes a hit. The 70-denier ripstop nylon used for the shell is noticeably thin and prone to wear if you're hard on your gear. If you regularly carry an ice axe, scramble over abrasive rock, or tend to toss your pack around, there’s a good chance you’ll eventually poke some holes in the pack body.
That said, we appreciate that REI used solid fabric—not mesh—for the side pockets, which helps avoid one of the most common failure points in lightweight daypacks. Still, the Flash 22 is one of the least durable hiking daypacks we’ve tested. For on-trail hiking, travel, or casual everyday use, it should hold up fine over time. And if a hole does form, a little gear tape can extend its life and add some character along the way.
To help fend off light moisture, REI treated the Flash 22’s shell with a DWR coating. In use, light rain tends to bead up and roll off the pack, and any pooling can usually be resolved with a quick flick of the fabric. This level of protection is perfectly adequate for typical summer hikes or shoulder-season outings when the forecast looks favorable.
However, the Flash 22’s thin shell fabric offers limited defense in heavier rain. In sustained downpours or winter conditions, water can start to soak through more quickly than with burlier daypacks that use multi-layer constructions and thicker fabrics. For those scenarios, we’d recommend pairing the pack with a rain cover—REI’s Ducks Back in an extra-small size fits well and runs $28.

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 REI Co-op Flash 22 is offered in a single size, and its fit adjustments are limited to the shoulder straps and hipbelt webbing—there’s no option to adjust the torso length. REI lists the pack’s fit range as accommodating torsos from 16 to 21 inches, but we’re skeptical it will feel especially comfortable for those near the upper end of that spectrum. At 5’10” with an 18-inch torso, I was able to achieve a reasonably good fit, but the pack does feel small overall and could feel undersized for taller users.
On the bright side, the hipbelt offers generous adjustability and fits waist sizes between 26 and 42 inches. For most hikers within the recommended size range—especially those of average or shorter height—the Flash 22 should fit well enough for light loads and shorter outings.
Osprey Daylite Plus ($80): More Structure and Support
The Flash 22 is a great budget option for those who don’t plan on carrying heavy loads—it’s about as simple as a daypack gets. But the Osprey Daylite Plus is an extremely popular alternative and for good reason. For an additional $20, the Daylite Plus offers considerably more support and structure, resulting in a higher level of carrying comfort, particularly with anything substantial in the pack. It’s more durable, too, so you don’t have to worry about it as much on the trail or in your car. You do sacrifice 2 liters of capacity with the slightly smaller Daylite Plus, but the Flash likely will feel pretty darn awkward when fully loaded anyway. In the end, we appreciate the value of the Flash and it’s a fun pack to have for quick jaunts, but the Osprey can handle longer hikes quite a bit better. For more, read our review of the Daylite Plus.
Deuter Speed Lite 21 ($85): And Even More...
The Speed Lite 21 costs $25 more than the Flash, but even that slight price bump gets you a noticeable step up in craftsmanship. Like the Flash, it’s best suited for short outings rather than carrying a full load, but it offers more structure thanks to its hard plastic perimeter hoop. The shoulder straps and back panel also feature a mesh-and-foam-cutout design, which is both more breathable and more supportive than the Flash’s minimal padding. While we like the Flash’s interior organization, some hikers may prefer the Speed Lite’s dorsal drop pocket for its easier access to gear. Both packs are lightweight and highly packable, making them great for short trips or as secondary packs on bigger expeditions. However, if you plan to wear your pack for extended periods, the Speed Lite’s added comfort and structure make it worth the extra cash. For more, read our review of the Speed Lite 21.
Black Diamond Distance 22 ($230): A Souped-Up Summit Pack
Hear us out—yes, the Distance 22 costs a whole lot more than the Flash, but if you’re looking for a packable summit daypack with far better technical chops, this might be your answer. Like the Flash, it lacks structure, making it just as easy to stash, but its running vest-style harness offers a night-and-day difference in both carrying comfort and organization. And as you’d expect given the higher price tag, it’s better constructed, made with hardier materials, and outperforms the Flash in nearly every aspect. This isn’t the pack to buy for casual summer strolls, but for seasoned scramblers and mountain athletes, the Distance is an easy winner. For more, read our Distance 22 review.
This pack is truly minimalist, both in its design and its impact on your finances. It functions well as a summit pack on backpacking trips, a travel daypack, or a simple tote for quick summer hikes. However, comfort and support fall by the wayside.

I’ve gifted the REI Co-op Flash 22 multiple times for a reason: it’s genuinely useful across a wide range of applications, from hikes and summit pushes to travel and even everyday use around town. That said, its frameless design and minimal padding make it a poor match for heavier loads or gear-intensive outings. But if you pack light and want a versatile bag that practically disappears on your back, the Flash 22 is an exceptional value at just $60.
