A Review of the Cotopaxi Allpa 35L
Cotopaxi has been a familiar name in the travel bag space for years, and the Allpa 35L is the pack most people mean when they bring up the brand’s carry-on lineup. It is a suitcase-style backpack that opens flat like luggage, organizes like a proper carry-on, and still carries on your back like a backpack when you need to move fast. We have used one as a main travel bag and as a secondary bag on trips where a partner or friend carried the rest, so this review covers both roles.
The short version: it is one of the more thoughtfully organized 35-liter packs on the market, built from genuinely tough recycled fabric, and comfortable enough for airport-to-accommodation walking. It is not a one-bag solution for everyone, and it is not cheap. Here is where it earns that price and where it does not.
Cotopaxi Allpa 35L
A durable, well-organized carry-on backpack that suits travelers who want suitcase-style access without giving up backpack comfort. Best for trips of a few days to a couple of weeks; less ideal if you need to fit your entire life in one bag indefinitely.

How it opens and organizes
The Allpa’s biggest advantage over a normal top-loading backpack is how it opens. Unzip it fully and it lays flat like a suitcase, with the whole interior visible at once. There is no digging to the bottom for a phone charger buried under three days of clothes.
Inside, you get one large mesh-paneled compartment, a medium one, and a small one, plus a separate zippered pocket with a key clip for things you want to find without unpacking anything else. The padded, fleece-lined laptop sleeve holds up to a 15-inch laptop and sits against the back panel, which is the safest spot in any bag if you drop it. A stretch mesh pocket on the outside holds a water bottle up to about a liter, and there is a small front organizer pocket for a passport, cables, or a phone.
The main compartments are lined with mesh so you can actually see what is inside each one, which matters more than it sounds like it would. When you are unpacking into a new room for the fifth time in a month, being able to glance into a cube-style compartment and immediately know it holds your underwear and socks saves real time. The mesh also lets a little air through, which helps if you toss in slightly damp gym clothes or a swimsuit for an hour before you can hang it up properly. For trips where wet gear needs real quarantine, we use weatherproof cubes like the Matador Gear Cube Set.
Material and build quality
Cotopaxi builds the current Allpa from two layers of recycled nylon: an 840-denier TPU-coated shell for weather resistance and an 840-denier ballistic ripstop layer for abrasion resistance, with a recycled ripstop polyester lining inside. In practice, that means the fabric has a slightly stiff, coated feel rather than the soft touch of a duffel bag, and it sheds light rain well enough that a drizzle on the walk to a bus stop is not a problem. We would not call it waterproof, and Cotopaxi does not either, so plan on a rain cover or a dry bag for anything electronic if you are caught in a real downpour.
The zippers are YKK, which is the detail we look for on any bag in this price range, and the main compartment zippers are lockable, so a small TSA-approved lock will actually do something useful. After regular use through overhead bins, taxi trunks, cobblestone streets, and being tossed onto hostel bunks, the stitching and zipper pulls on ours have held up without any fraying or snags. That kind of durability is the main reason to pay Cotopaxi’s price instead of a $70 lookalike.
Comfort: how it actually feels on your back
At just under 3 pounds empty, the Allpa is not the lightest 35-liter pack you can buy, but the weight goes toward things that make it more comfortable, not less. The shoulder straps use an air mesh panel that breathes noticeably better than the foam straps on cheaper packs, and the hip belt is removable if you would rather clip it away for a quick walk to the gate. With the hip belt cinched and the load lifters adjusted, the pack transfers weight onto your hips instead of pulling on your shoulders, which is the difference between a comfortable 20-minute walk to your accommodation and a sore-shoulder one.
We would not take this bag on a multi-day trek. It is not built for that, and Cotopaxi does not market it that way. But for airports, train platforms, city sidewalks, and the occasional longer walk when a taxi is not worth it, it carries well. Packed to capacity with clothes, a laptop, and a pair of shoes, ours sits around 20-22 pounds, and that is roughly where the straps start to feel like straps instead of disappearing.
Fitting it under airline limits
At 22 x 12 x 10 inches, the Allpa 35L sits right at the upper edge of typical carry-on allowances. You can check it against specific airline carry-on limits here. It will clear most major carriers’ overhead bin sizing without a problem, but the 10-inch depth is where it can get tight on stricter budget or regional airlines, especially once it is packed full and the sides bulge. We treat it as a reliable overhead-bin bag rather than a guaranteed under-seat personal item, and if you are flying a carrier known for aggressive gate-checking of bags, it is worth checking their specific limits before you travel rather than assuming.
What we like
- Suitcase-style opening makes packing and repacking fast
- Genuinely durable recycled fabric and YKK lockable zippers
- Air mesh straps and a removable hip belt make it comfortable loaded
- Mesh compartments make it easy to see what’s inside without unpacking
- 15″ padded laptop sleeve sits safely against your back
What we don’t
- Structured compartments feel boxy and limiting if you prefer one open cavern
- 10-inch depth can push the limit on stricter budget-airline sizers when full
- Not spacious enough for full-time travelers with bulky gear or cold-weather layers
- $230 price puts it well above basic travel backpacks
Who should buy this bag
The Allpa 35L makes the most sense for travelers who want one dependable bag for trips of a few days to a couple of weeks, the exact window we walk through in carry on luggage for 2 weeks, and who value being able to see and organize everything at once. It is a strong fit for digital nomads who keep a lean tech setup, couples who split gear across two bags, or full-time travelers who want a reliable secondary bag alongside a larger main pack.
It is a weaker fit if you are trying to live indefinitely out of a single bag and need more room for camera gear, cold-weather clothing, or a bulkier remote-work setup. It is also not the bag to choose if you strongly prefer one open compartment over built-in structure, since the divided layout works against you if you do not pack with any system. If you are still building that system, how to pack one bag for travel is the better starting point than another bag review.
If we were recommending one carry-on backpack to a friend who wanted structure, easy access, and a bag that could survive years of frequent travel, the Cotopaxi Allpa 35L would be near the top of the list. It costs more than a basic travel backpack, but the organization and durability make it easy to justify for anyone who travels often enough to feel the difference.
