How to Read This REI Backpack Review

The point of any REI backpack review is matching a Co-op model to your trips, since the lineup spans budget daypacks to lightweight and adjustable multi-day packs. Focus on capacity, suspension, weight and value, and REI’s strong return policy makes any of them a low-risk buy.

Match Capacity to Trip Length

REI sizes its packs by liters. Day hikes suit the 22L Flash, big days and light overnights fit the 35L Traverse, and multi-day trips want the 50-60L Flash, Flash Air and Trailmade. Match capacity to your longest common trip so the pack rides well when not full.

Most hikers are well served by one Co-op daypack and one multi-day pack. If you are unsure, the versatile Flash 22 and Flash 55 cover day hikes through multi-day trips affordably, which is a big part of REI’s appeal for hikers building a first kit.

Weigh Value Against Refinement

REI Co-op packs are built to deliver strong performance for the price, so they often match pricier brands on the basics while trading some refinement in suspension or materials. That value focus is why Co-op packs land on so many best-budget lists across capacities.

Decide how much refinement you need. For weekend trips at moderate weight, a Co-op pack performs close to packs costing far more. For heavy loads or long thru-hikes, premium suspensions pull ahead, so weigh REI’s value against your trip demands.

Consider Weight and Adjustability

The Co-op lineup spans ultralight roll-top packs under two pounds to durable haulers over three, and many offer adjustable torsos, which is forgiving for a first serious pack. Lighter models like the Flash use thin nylon to cut weight, while haulers add structure and durability.

Match weight and adjustability to your loads. The adjustable Flash and Trailmade are forgiving for a range of bodies and moderate loads, while the ultralight Flash Air suits weight-conscious hikers with light kits. Load-test if you can, since fit and comfort vary by model.

Factor In Durability and Use

Durability varies across the Co-op line, from thin ultralight nylon on the Flash to thicker fabric on the Traverse and travel-ready Ruckpack. Match fabric to your terrain, and consider whether the pack needs to cross over to travel, since some Co-op packs are built for both.

Decide how rough you are on gear and where you will use the pack. Scramblers and frequent hikers should favor thicker-fabric models like the Traverse, while occasional weekenders can run lighter packs. REI’s variety means there is a Co-op pack for most uses and budgets.

Top Picks From This REI Backpack Review

These six span a budget daypack to a lightweight multi-day pack and a travel crossover, covering the core of REI’s Co-op lineup. This REI backpack review lays out the specs in the table, then breaks down who each model suits and its honest drawbacks.

REI Co-op Flash 55 — Best Lightweight Multi-Day

The Flash 55 is REI’s standout value multi-day pack. It is customizable with removable pockets and an adjustable torso, light at around two pounds ten ounces, and carries a weekend or thru-hiking load well, which is why reviewers routinely name it a top budget pick. It is the natural first serious pack.

The thin nylon is less durable than thicker builds, and comfort drops with loads north of about 30 pounds, while the customizable pockets can feel bulky. For light-to-moderate weekend loads, though, its blend of low weight, comfort and value is excellent at this price.

REI Co-op Trailmade 60 — Best Budget Hauler

The Trailmade 60 is built for accessibility. It is widely adjustable to many body types, carries an overnight kit and then some with its 60L capacity, and keeps things simple and affordable. For beginners who want a forgiving fit and real capacity without spending up, it is a smart value.

It is short on flash and premium comfort features, and its suspension is basic compared with pricier packs, so it will not pamper you on long, heavy days. For weekend trips and new backpackers dialing in their fit, though, its adjustability and value make it an easy recommendation.

REI Co-op Flash 22 — Best Daypack

The Flash 22 is a longtime value favorite. At about 14 ounces it is featherweight, uses recycled ripstop nylon, and includes a hydration sleeve and a removable sit-pad backpanel, all at a budget-friendly price. For light day loads and beginners, it is the easy Co-op daypack pick.

The thin nylon trades some abrasion resistance, and there is no real frame or hipbelt support, so it gets floppy under heavier day loads. It is best kept to light kits. Within that range, though, few daypacks match its blend of low weight, simplicity and value.

REI Co-op Traverse 35 — Best for Big Days

The Traverse 35 is a comfortable, durable pick for big day loads and even light overnights. It uses thicker fabric than many daypacks, adds an adjustable back panel, hipbelt pockets and an included rain cover, and carries heavier day gear well. It is a versatile, well-built Co-op option.

At around three pounds five ounces it is heavier and larger than a pure daypack, and past versions had chest-strap durability issues that recent models address. For hikers who want durability and capacity for big days, though, it is a strong, adjustable choice.

REI Co-op Flash Air 50 — Best Ultralight

The Flash Air 50 is one of REI’s lightest packs at a genuinely accessible price, tipping the scale under two pounds. For hikers who want to try going light without cottage-brand spend or wait times, it delivers a lot of weight savings for the money in a mainstream, easy-to-buy package.

To hit that weight it uses minimal padding and support and lighter-duty fabric, so it tops out near 30 pounds and is less durable than premium ultralight packs. As an affordable entry into ultralight backpacking, though, its value is excellent for weight-conscious hikers.

REI Co-op Ruckpack 40 — Best Travel Crossover

The Ruckpack 40 is the trail-meets-travel pick. It pairs a panel-loading clamshell design and a laptop sleeve with enough trail features to handle light hikes, so it works for a minimalist overnight and a flight abroad alike. For hikers who want one pack for trips and travel, it is versatile and affordable.

It is not a true internal-frame hauler for heavy loads, no water bladder is included, and its travel focus means less trail-specific suspension than dedicated hiking packs. As a durable, versatile crossover at a fair price, though, its dual-purpose design is genuinely useful.

What REI Co-op Pack Prices Look Like in 2026

REI Co-op packs are value-focused, so timing helps stretch the savings further. A couple of current market forces affect what these packs cost and when to buy, without changing which model fits your trips.

Tariffs Still Pressure Materials

Co-op packs use imported nylon and aluminum frame elements, and metal tariffs remain in place. Brands have described future pricing as a moving target, so if you already know the model you want, buying now is a reasonable hedge rather than waiting for prices that may creep up.

The effect is uneven. Value-focused Co-op packs are exactly the mid-tier segment seeing more discounting as retailers clear pre-tariff inventory, so watching for closeouts on last year’s colors is often the surest way to save on an already affordable pack.

Watch REI’s Sale Events

Beyond the usual fall calendar, with Prime Big Deal Days in early October and Black Friday and Cyber Monday in late November, REI runs its own member sales and coupon events. Timing a Co-op pack purchase to those can stack savings on already strong value.

Buying early in the season also secures the sizes and colors that thin out on popular Co-op packs. Build a wishlist now and track prices into fall and REI’s member events, and a value pack can get even more affordable.

Lean on the Return Policy

REI’s generous return policy makes trying a Co-op pack low-risk, which is a real advantage when dialing in fit. Buy the size you measure for, load-test it at home or on a short hike, and return or exchange if the fit is not right rather than settling for discomfort.

If a specific model or size is prone to selling out, buy early rather than gambling on peak stock. Missing the right size costs more than a small discount, especially in less common capacities that vanish first each fall.

Frequently Asked Questions

These are the questions hikers ask most when comparing REI Co-op packs.

Which REI backpack review pick is best for beginners?

For most beginners, the REI Co-op Flash 55 or Trailmade 60 offers the best mix of value and versatility. This REI backpack review rates the Flash as the lightweight value multi-day pick and the Trailmade as the budget hauler, both forgiving and affordable for new backpackers.

Are REI Co-op packs as good as premium brands?

On the basics, often yes. Co-op packs match pricier brands on fit and capacity for weekend loads while costing less, which is why they win budget honors. For heavy loads or long thru-hikes, premium suspensions pull ahead, so it depends on your trip demands.

Are REI packs durable?

It varies by model. Lightweight packs like the Flash use thin nylon that needs gentler handling, while the Traverse and Ruckpack use thicker, more durable fabric. Match the model’s fabric to your terrain, choosing thicker builds if you scramble or hike frequently.

Do REI packs come in women’s fits?

Many do, in women’s-specific or adjustable versions with shorter torsos and re-shaped straps. The Flash and Traverse, for example, come in fits that suit a range of bodies. Fit is individual, so use REI’s return policy to try a pack loaded and confirm comfort before committing.
