Who Should Buy This#
The Allpa 35L hits a sweet spot for travelers who want to live out of one bag without giving up the organization of a rolling suitcase. It delivers a full clamshell layout, lockable security, and a hideaway harness that competing travel packs charge $250-350 for. You get a structured, protective carry that still slides into the overhead bin.
Perfect for:
- One-bag travelers who want to skip baggage carousels and pack a full week's gear in a single carry-on
- Digital nomads who need a padded 15-inch laptop sleeve plus tablet protection for working on the road
- Hostel and city hoppers who want lockable zippers to secure belongings in shared rooms
- Weekend adventurers who want one bag that handles a flight, a train, and a trail without looking out of place
Design & Build Quality#
The Allpa 35L uses a boxy, structured shape that holds its form and protects what's inside. The shell is a TPU-coated recycled polyester that shrugs off light rain and scuffs, with bold color-blocked panels that make it easy to spot on a luggage rack. Cotopaxi builds the whole pack from 100% recycled fabrics, and it carries the brand's lifetime repair guarantee.
Construction details show the travel focus. There are three padded grab handles (top, side, and bottom) so you can haul it like a duffel, a luggage pass-through strap that slides over a roller-bag handle, and a back panel that zips closed over the suspension system. At roughly 3.5 pounds empty, it's not the lightest 35L pack, but the weight buys durability and a harness that actually carries a full load.
Key Features#
Suitcase-Style Clamshell Opening#
The Allpa unzips flat into two equal halves, exactly like a hard-shell suitcase. One side has a large zippered mesh compartment and the other splits into two more mesh pockets, so you can separate clean clothes, dirty laundry, and accessories at a glance.
This layout is the core reason to choose the Allpa over a traditional top-loading backpack. You stop digging from the top to reach the bottom, and you can pack to full capacity because the bag opens completely. Compression straps inside each half cinch everything down so nothing shifts in transit.
Lockable YKK Zippers#
Both main compartments close with burly YKK zippers that meet at lash points you can secure with a small TSA-style padlock. That turns the Allpa from an easy grab-and-go target into a meaningfully harder one.
For anyone staying in hostels, shared dorms, or leaving a bag in a locker, this is a genuine peace-of-mind feature. You can lock the main clamshell shut and walk away, something most travel backpacks simply can't do.
Stowable Suspension Harness#
The shoulder straps and hip belt are padded with air mesh for ventilation, and the hip belt transfers weight off your shoulders on longer carries. When you don't need them, the whole harness zips away behind a back panel.
Hiding the straps does two things. It protects them from getting caught in conveyor belts if you check the bag, and it gives the Allpa a clean, briefcase-like profile when you carry it by the handles through an airport or office. Check current availability: View on Amazon
Travel-Ready Organization#
Beyond the two main compartments, a padded back sleeve fits up to a 15-inch laptop with a separate tablet pocket alongside it, so your electronics stay protected and easy to pull at security. A top zip pocket holds passports and a phone, and an exterior stretch pocket carries a water bottle.
An included rain cover tucks into its own pocket and pulls over the whole pack when the weather turns, which is the kind of detail that separates a travel pack from a school backpack.
