REI Co-op Ruckpack 40 Pack Review

Overview

The REI Co-op Ruckpack 40 is a carry-on-sized travel pack built with a genuine backpacking pedigree — it borrows the tapered shape, padded suspension, and organizational DNA of a hiking pack and points it at airports instead of alpine passes. It’s aimed at the traveler who wants one bag that can handle a flight, a city, and a weekend trailhead without switching luggage, rather than someone chasing minimum base weight.

Performance

The defining trait of the Ruckpack 40 is that it doesn’t feel like a duffel bag with straps bolted on — it feels like a pack first. The tapered backpacking pack shape makes it ideal for wearing straight from the airport to the base of a rock climb, with two zippers spanning top to bottom for easy access, and the tapered shape lets heavy gear settle to the bottom while organizational side pockets hold plane snacks and electronics. That last part matters more than it sounds — a lot of travel packs pack like a brick because everything shifts to the bottom, but the taper here actually keeps weight where a hipbelt can manage it.

Speaking of which, the harness is the standout feature according to most reviewers. Carrying comfort is a clear strong suit of the Ruckpack 40, and it also features an excellent organization layout that makes it easy to divvy up gear and clothing. One tester specifically used three packing cubes in the main compartment to keep clothes and toiletries organized, with smaller items easy to distribute in the internal and external pockets. If you’ve ever tried to cube-organize a top-loading backpacking pack and given up, this is the pack that fixes that problem — the full clamshell opening means you can actually see and reach everything.

Pocket layout is thoughtful rather than an afterthought. The two stretchy mesh exterior pockets securely fit a 24-ounce water bottle or a pair of sandals without anything falling out when sliding the pack into an overhead bin, the top pocket has a zipper extending across the pack with a clip for keys, and one side has an additional pocket with an internal zipper plus a smaller drop-in pocket. REI clearly spent time here — a dedicated padded sleeve cradles a 15-inch laptop, and a series of internal mesh pockets keep essentials sorted instead of the usual free-for-all main compartment.

On the security front, there’s one wrinkle worth knowing about before you buy: you can actually access the main compartment from the side mesh pocket, which does not have a lockable zipper, so it isn’t a foolproof security solution but it’s better than nothing. If you’re the type who locks every zipper pull together on a hostel dorm bed, that’s worth knowing — it’s not a dealbreaker, just don’t assume the whole bag is lockable.

Weather protection is handled with an included rain cover rather than relying purely on face fabric DWR. There’s a dedicated zip compartment on the bottom of the bag that holds a rain fly, and while the pack offers some weather resistance on its own, the rain cover ensures that next level of protection, deploying quickly and staying on well. For hiking-adjacent trips where you might get caught in a shower between the trailhead and the car, that’s a genuinely useful inclusion that a lot of travel packs skip.

Where it comes up short is airline-seat compatibility and, unsurprisingly, weight. It’s a great sidekick for weekend use or a carry-on bag, but it may not fit under an airplane seat if fully packed — though the harness system tucks away with ease if it must be checked. At 1,220 g (2.7 lb), this is meaningfully heavier than dedicated ultralight travel packs or frameless daypacks in the same volume class, though that weight buys you a real suspension system rather than a glorified stuff sack with straps — a fair trade if you’re regularly walking any distance with a loaded bag rather than just wheeling it through an airport.

Pros & Cons

Pros

• Genuine backpacking-style suspension (padded hipbelt, load lifters) makes it comfortable for actual walking, not just terminal shuffling
• Clamshell opening plus a top quick-access pocket covers both “dig through everything” and “grab my passport” use cases
• Thoughtful pocket layout — bottle pockets, laptop sleeve, key clip, side organizer — without feeling over-engineered
• Included rain cover with its own dedicated pocket
• Harness stows away cleanly when the bag needs to go in checked luggage

Cons

• At 2.7 lb, it’s heavier than purpose-built ultralight travel packs
• May not fit under an airplane seat when packed full
• Side mesh pocket allows main-compartment access and isn’t lockable, so it’s not a fully secure setup for sketchy hostels or transit
• 40L is a bit large for true carry-on-only minimalists who prefer 30-35L

Who Should Buy This

This is the right pack for someone who wants one bag to cover a flight, a few days in a city, and a shoulder-season hike or two — think weekend warriors, digital nomads who value comfort over ounces, or hikers who occasionally need a travel-first pack that can still handle a loaded trail day. If your trips are strictly carry-on-only with no walking involved, or you’re chasing the lightest possible travel setup, there are lighter, more minimalist packs worth a look instead.

Verdict

The Ruckpack 40 earns its keep by taking backpacking-grade comfort and organization and pointing it at travel use, and it mostly succeeds — the suspension and pocket layout are genuinely well thought out. It’s not the lightest or most airline-seat-friendly carry-on out there, but for anyone who wants a pack that can walk as well as it flies, it’s a solid 7.8/10.
