Quick verdict
Choose the Peak Design Travel Backpack 45L if this matters most: compresses to a smaller, stricter-sizer-friendly footprint when needed. Choose the Cotopaxi Allpa 35L Travel Pack if you'd rather have: 35L sits closest to budget-carrier personal item limits among purpose-built travel packs.
Head-to-head
The differences that actually change the buying decision.
The Short Answer
Buy the Cotopaxi Allpa 35L if you want a reliable carry-on backpack with a suitcase-style opening at roughly half the price, without needing expansion or camera-specific organization.
Where They Match
Carry-on sizing at their compressed/base size: Both sit close to 35L when the Peak Design pack is compressed, clearing most standard sizers.
Durability: Both use heavier-duty shell fabrics designed for repeated travel abrasion rather than occasional use.
Warranty support: Both brands back their bags against manufacturing defects.
Where Peak Design Wins
Expansion range: Genuinely useful for travelers whose trip length or packing needs vary, compressing down for a strict sizer and expanding for a longer trip.
Camera cube compatibility: A specific, deliberate feature for photographers that the Allpa has no equivalent for.
Access points: Three separate access panels reach different sections of the pack without fully unpacking.
Where Cotopaxi Wins
Price: Roughly half the cost of the Peak Design pack for a bag that covers the core carry-on use case well.
Simplicity: A single full-wrap zipper is faster to operate than MagLatch closures and compression straps.
Weight: Lighter empty weight, which matters over a full day of carrying.
Who Should Buy Each
Cotopaxi Allpa 35L: travelers who want a dependable carry-on backpack without camera-specific organization or expansion, at a meaningfully lower price.

FAQ
Common 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.
