The Cotopaxi Allpa 35L Del Dia Travel Pack is an easy-to-organize, comfortable-to-carry bag for getaways lasting just a few days or a whole week.

It’s one bag that can do it all. This is a great all-around bag for any traveler who’s dedicated to packing light, or for a smaller person who wants less to carry. This bag has handles on three sides, so it’s easy to grab no matter where you’ve stowed it; a handle pass-through lets you attach it to carry-on luggage, as well. It’s also protected by a full lifetime warranty, and it has the build quality to back that up. After more than six years of testing, I’ve found that this single backpack (plus a personal item) has replaced nearly every travel bag or piece of luggage I use.

It comes in various sizes, but the middle-of-the-road version is the best. Cotopaxi also makes the Allpa in 28-liter and 42-liter sizes. But for us, the 35-liter bag is the best option. The 42-liter version became heavy for our testers to carry when fully packed, and we’d prefer to see a more-robust hip belt on that bag. The 28-liter bag was a touch small for our testers, and its internal organization seemed a little much for shorter trips, such as an overnight jaunt. Cotopaxi also makes a hip pack that’s designed to fit snugly into the Allpa bag’s front top compartment. It’s a neat little addition to the bag, and it’s worth getting if you like wearing fanny packs while you travel.

Its materials are strong. The Allpa pack is made with 100% recycled 840-denier ripstop nylon. (Denier is a measure of a fabric’s fiber thickness.) The material feels similar to a strong canvas, but it has a more prominent weave. This is the type of bag that’s as easy to slide into an overhead compartment as it is to toss into the back of a rusty pickup truck. It also comes with a rain fly, a unique feature in this category.

Cotopaxi makes the Allpa pack with either a TPU (nylon bonded with a water-resistant polyurethane membrane) or classic nylon construction on the back of the bag. We’ve tested both styles over the years. Although TPU provides additional water resistance, we found over time that the original TPU-coated fabric that Cotopaxi used had a tendency to break down. When we tested the updated version in 2024, Cotopaxi had changed the fabric to address this issue. We’re continuing to test the new bags to see how they last.

It’s organized. The Allpa bag has a clamshell design, so it opens like a hard-sided suitcase—a large YKK zipper (the industry leader) runs around three sides of the bag, allowing it to fall open into two halves when you unzip it. On the right side is a deep compartment that’s spacious enough for two large packing cubes or half a suitcase’s worth of clothing, which you access through a mesh zippered flap. On the left, you’ll find space for one more medium-size packing cube behind a zippered flap. Above that are two smaller pockets with high-visibility backing—useful when you’re looking for hard-to-differentiate personal items. Cotopaxi has added a stretch mesh pocket for a water bottle up to 1 liter.

It’s secure but still accessible. The Allpa pack has two side-access zippers, which are great for on-the-go access, especially when the bag is hanging from your shoulder. One of them reveals a flat computer pocket with a padded false bottom, so if you drop the bag, it won’t land on the corner of your computer. The other reveals a “secret” pocket with a hidden zipper and access to the main compartment. All of the main-compartment zippers are protected by security loops, which you thread the zipper through at the end of its run; doing so prevents anyone from subtly or quickly grabbing a zipper and opening your bag when you aren’t paying attention.

It’s comfortable to carry. The Allpa bag’s hip belt—which you can stow while the bag is on your back—is good enough that it’s comfortable to wear when you need it. With or without the hip belt, the Allpa bag is comfortable to carry over long distances. However, folks who have longer torsos (over 19 inches) may find that the waist belt sits a little high off the hips, unless you fully extend the shoulder straps. Speaking of shoulder straps, unlike the ones on our other picks, the Allpa bag’s straps are contoured to fit both people who have large chests and those with small chests. It isn’t a specifically gendered design, but our female tester noticed the improvement right away.

Flaws but not dealbreakers

• Though this pack is well organized for packing, it’s less ideal as a mobile office. The Allpa pack has a minimal amount of administrative organization—places to keep pens and papers, spaces to hold tickets, and so forth. This is where a good personal item comes in handy. However, if you want to travel with just this one bag, it has a few nooks you can hide things in. And the front organizer is deep enough that you can fit several small organizing pouches, if you want, or the aforementioned fanny pack.
