About
What it is.
Cotopaxi's Allpa 42L is a soft-sided travel pack built as carry-on-style luggage rather than a hiking rucksack, with a clamshell zip opening, a padded laptop sleeve, and a mesh-pocketed interior for organizing clothes and gear separately. The TPU-coated polyester shell and 100% recycled ripstop lining shed light rain, and a luggage pass-through strap lets it ride on top of a rolling suitcase handle for airport transfers.
It's suited to people who move between transit, hostel, and hotel in the same day and want one bag for both the flight and the walk to the room. The "Del Dia" colorway runs each pack in a one-of-a-kind hue using deadstock fabric, so no two are identical—part of Cotopaxi's broader use of recycled materials across the Allpa line.
