Our newly redesigned Allpa 35L reflects our quest for pack perfection. While all the customer-favorite features of our bestselling Allpas remain, we’ve made a few game-changing updates.  New features include better weight distribution and air mesh shoulder straps for an ultra-comfortable carry, an exterior stretch water bottle pocket, and a luggage pass-through strap that easily slides over the handle of a roller bag (like our Allpa Roller Bags).
