Answers

Frequently asked questions

Is the Peak Design Travel Backpack 45L worth double the price of the Cotopaxi Allpa 35L?

For photographers who need camera cube compatibility, or travelers who genuinely need a bag that expands from a strict-sizer size up to 45L, yes. For a traveler who just needs a reliable carry-on backpack without those specific needs, the Allpa 35L delivers most of the core functionality (suitcase-style opening, durable shell) at roughly half the price.

Which is better for a photographer?

The Peak Design Travel Backpack 45L, clearly. Its compatibility with Peak Design's separate camera cube inserts is a specific, deliberate design feature that the Cotopaxi Allpa 35L has no equivalent for. A photographer carrying a camera body and multiple lenses will get more organized, better-padded storage from the Peak Design pack.

Which is easier to use quickly at airport security?

The Cotopaxi Allpa 35L's single full-wrap zipper is simpler and faster to open and close than the Peak Design pack's MagLatch closures and compression straps, which take a bit more practice to operate smoothly under time pressure.

Which is the better choice for a strict budget-carrier itinerary?

The Cotopaxi Allpa 35L, both because of its smaller base capacity and because it can't expand further and risk exceeding a tight sizer. The Peak Design pack can be compressed down for a similar sizer-friendly size, but its compressed footprint is still closer to 35L rather than genuinely smaller, so the Allpa 35L remains the safer default for this specific use case.
