Our Take:
3.9/5
We turn to REI for good value, and in some ways its mid-range Trail 25 pack ($100) delivers. The capacity is spot-on for most day hikes, the sturdy shell holds up well over time, and thoughtful touches like the included rain cover are appreciated. However, we were let down by its comfort—especially the lack of a true hipbelt—which limits its appeal for longer or gear-heavy outings. While not our top pick for full days on the trail, the competitively priced Trail 25 still holds some appeal for shorter hikes and casual use.

Pros

Can pull double-duty as an around-town pack.
Rain cover included.
Lots of attachment options on the exterior.

Cons

Overly thin webbing hipbelt is a miss.
It won’t be too comfortable if you fill it to the brim.
Lacks a mesh shove-it pocket on the outside.

I’ve long been a fan of REI’s Trail series—especially the larger 40-liter version—but the smaller Trail 25 is a noticeable step down in comfort and support. The main issue is the webbing hipbelt, which lacks padding and feels awkward when cinched, especially under heavier loads. It’s a stark contrast to the more traditional cushioned hipbelts commonly found on daypacks of this size, and the difference is easy to feel when carrying 10+ pounds.


That said, the REI Co-op Trail 25 isn’t without its positives. The lightly stiffened framesheet adds some structure and does a decent job of protecting your back from pokey items in the main compartment. Cushioning on the shoulder straps and backpanel is also respectable, and although the pack sits fairly close to your back (meaning it runs warm), the raised padding and cutouts dry reasonably quickly. In short, the Trail 25’s comfort would get a notable boost with a more supportive hipbelt like the one used on the Trail 40. As it stands, it’s serviceable for lighter loads, but falls short of top competitors like the Gregory Miko or Osprey Talon.

The Trail 25’s storage layout is straightforward and functional, hitting the basics most day hikers will need. The main compartment is generously sized, and the wide U-shaped zipper opening makes it easy to access gear—even items stuffed near the bottom. Inside the top flap, there’s a mesh zippered pocket with a key clip, ideal for securing small essentials. A hydration reservoir sleeve with a simple hook-and-loop strap rounds out the internal organization.

On the outside, two stretchy side pockets easily accommodate standard one-liter water bottles, and a small half-moon zippered pocket at the top/front provides a convenient spot for snacks or sunglasses. One notable drawback is the lack of hipbelt pockets, which means there’s no easy-access spot for a phone or GPS. The top exterior pocket can fill that role in a pinch, but I often used my hiking pants or jacket pockets instead.


The front daisy chains and shockcord loops provide gear-hauling options, like securing trekking poles or an ice axe. Overall, the Trail 25’s organization gets the job done, but like the rest of the pack, it lands squarely in the “just fine” category—not bad, but not particularly impressive either.

One upside to the Trail 25’s streamlined design is its relatively low weight. At 1 pound 13 ounces, it undercuts many competitors with similar or even smaller capacities—like the Osprey Talon 22 (2 lb. 6.1 oz.) and Gregory Miko 20 (2 lb.)—making it a reasonably light option for day hiking. It’s not as feathery or packable as REI’s Flash 22 (14 oz.), and it doesn’t compress as well for travel or use as a summit bag, but it still lies fairly flat when empty, and the hipbelt can be removed to further simplify the profile.

In a step up from REI’s more minimalist Flash series, the Trail 25 uses hardwearing 210-denier ripstop nylon across the exterior, with a similarly robust 200-denier polyester lining inside. This combination gives the pack a noticeably tougher and more confidence-inspiring feel compared to the thinner 70-denier Flash 22. I’ve had no hesitation squeezing through tight brush, scrambling over rock, or setting the pack down on rough surfaces—activities that would give me pause with lighter designs.


That said, the Trail 25 isn’t bulletproof. The base isn’t reinforced like some competitors (Osprey’s Talon, for instance, uses a burlier 420-denier base fabric), and the side pockets are primarily mesh, which can be prone to snags or tears with careless use around vegetation. However, the lower third of the side pockets is solid nylon, helping with longevity. Overall, the Trail 25 is a reliably durable option that should hold up well to regular trail use.

The REI Co-op Trail 25 is fully equipped for year-round hiking in all but the harshest conditions. The pack body features a durable water-repellent (DWR) finish that effectively sheds light rain and snow, while the thicker shell fabric slows down moisture intrusion during surprise downpours. And for heavier precipitation, REI includes a dedicated rain cover that stows neatly in a zippered compartment at the base of the pack—a thoughtful addition that many competitors charge extra for.


The rain cover fits snugly and includes a strap to keep it secure, but it’s not totally immune to wind. On a gusty spring hike in Washington’s Enchantments, I noticed loud flapping when the wind turned the rain sideways. Still, the cover stayed put and kept everything inside dry. For most day hiking conditions, the Trail 25’s protection is more than sufficient.

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 Trail 25 comes in two size options: an XS–XL that fits waist sizes from 28 to 46 inches, and an XXL–4XL for waists between 42 and 58 inches. Both versions are offered in a single, fixed torso size with a listed fit range of 16 to 20 inches. With an 18-inch torso and 31-inch waist, I found the XS–XL Trail 25 fit me well—aside from my earlier comfort-related gripes about the hipbelt, it was perfectly serviceable.


That said, it’s worth noting there’s no torso adjustment built in—the shoulder straps are stitched in place, so dialing in a more custom fit isn’t possible. This could be a limiting factor for those who fall near the edges of the torso range. But it's a reasonable tradeoff at this price point for most casual day hikers who don’t need a perfectly snug fit.

Deuter Speed Lite 21 ($80): A Touch of European Class
Like the Deuter Trail, the Speed Lite 21 is a simple and packable daypack with a webbing hipbelt, but it features a more refined design with a sleeker shape and the addition of a shove-it pocket on the back. Its back panel and shoulder strap padding aren’t as beefy as the Trail’s, but in a pack not meant to carry significant weight, we appreciate the airy, lightweight feel. What the Speed Lite lacks is the Trail’s myriad attachment points, including trekking pole storage. However, for $20 less and with an uber-functional front stuff pocket (which we truly think every pack should have), we’ll take the Speed Lite. For more, read our review of the Speed Lite 21.

REI Co-op Flash 22 ($60): Rock-Bottom Price, Great Packability
The REI Flash 22 is even more budget-friendly and pared down than the Trail 25, but its biggest strength lies in its simplicity. Weighing just 14 ounces and compressing small enough to fit in a larger pack or duffel, it’s an excellent option for travel or summit pushes. And despite its minimalist design, it still offers a surprising amount of storage, including two interior drop pockets, side water bottle pockets, a zippered side-entry pocket, and a trekking pole holder. That said, unless you specifically need a super minimalist pack, the Trail 25 is likely the better choice. It’s more durable (210D vs. 70D), has better structure for carrying heavier loads, and its zip-top design allows for easier access to the main compartment. For more, read our Flash 22 review.

3.9/5

One of two budget-oriented REI packs that we tested, the Trail 25 sports a no-nonsense design that’s let down by its thin webbing hipbelt. While it has enough room for a day’s worth of supplies, the middling comfort makes it less of a value buy.

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.

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.

Is the Trail 25 for You?

Hiking on forest trail with the REI Co-op Trail 25 hiking daypack

The REI Co-op Trail 25 checks enough boxes to be a decent choice for casual day hikers, but it doesn’t stand out in any major way. The daypack is reasonably light, has solid durability for the price, and includes functional extras like a rain cover. That said, comfort is middling due to the minimalist hipbelt and fixed torso fit, and there are better options out there for carrying heavier loads. If you mostly take short hikes and pack light, the Trail 25 gets the job done, but there are more refined designs for just a bit more money.
