Key Features
The full-wrap zipper opens the main compartment flat like a suitcase, so you can pack and access your gear without digging. Compression panels keep everything snug once you zip it back up.
At 19×12×9 in and 28L, this pack fits in most overhead bins and meets standard carry-on size guidelines — so you can skip the checked bag line entirely.
Constructed from 100% recycled 840D TPU-coated and ballistic ripstop nylon — water-resistant and tough enough to handle airports, cobblestones, and everything in between. Backed by Cotopaxi's lifetime warranty with repair, replacement, or trade-in coverage.
The trolley sleeve on the back panel slides right over a roller bag handle, keeping the pack secure and your hands free when you're navigating a busy terminal.
Expert Take
If you're a one-bag traveler or just someone who's tired of waiting at baggage claim, the Allpa 28L is one of the more practical packs in this size range. The suitcase-style opening is a real convenience when you're in a hotel room or pulling things out at security. I'd recommend it for weekend trips and short work travel — it's just enough space without feeling like you're hauling a full pack around. The recycled materials and lifetime warranty are a nice bonus for anyone who wants a bag they can feel good about buying and keeping for years.
