Our Take:
4/5
Simple and affordable, the REI Co-op Flash 22 ($60) is about as good as it gets for travel and short day hikes. Its streamlined build is impressively light and packable, with just enough storage to keep your essentials organized. However, the lack of structure means carrying comfort takes a real hit with bulky gear or loads over 10 pounds. Still, for outdoor adventurers of all kinds, it’s a highly versatile and handy addition to the gear closet.

Pros

Extremely affordable for a pack with a good amount of design quality.
Super lightweight and packable.
The removable foam backpanel doubles as a sit pad.

Cons

Lack of structure makes for floppy, ill-distributed loads.
Thin, 70-denier fabric isn’t very durable.
Few adjustment options.

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 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 pack, 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 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 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 packs 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 is perhaps the most effective way to reduce environmental impact—the longer it lasts, the less it needs to be produced. Our proprietary longevity rating evaluates overall build quality based on factors such as materials, fabric denier, component durability (including zippers and toggles), real-world performance as reported by our field testers, and our experiences with the brand.

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.

Deuter Speed Lite 21 ($80): Better Support on a Budget
The Speed Lite 21 costs $20 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 ($200): 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.

One of the most affordable packs here, the Speed Lite is a simple model that can get the job done for carrying light loads on short to moderate hikes, but not much more. With a small compressed size, it’s a great pairing for those looking for a travel or summit pack.

The Distance wants to turn you into a mountain-eating speed demon. This light pack has storage for every gel packet and wicking layer you possess, and its beefy running vest-style harness hugs it close to your body on scrambles and trail runs. Make sure not to overload what little support it offers, though.

Is the Flash 22 for You?

Hiking up forest trail with the REI Co-op Flash 22 hiking daypack

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.
