Summary
Wirecutter's top carry-on pick and a community favorite for its suitcase-style opening, bomber durability, and versatility across hiking, work, and travel. Costs significantly less than Peak Design with minimal compromises.
The gold standard for one-bag travel, with pitch-perfect organization and a suitcase-style clamshell opening. Wirecutter and multiple long-term owners consistently rank it at the top after years of real-world use.
Pros
- Clamshell U-shaped opening for easy suitcase-style packing
- Extremely durable construction — closest rival to Aer in durability per BetterTrail testing
- Versatile enough for hiking, work, and travel use
- Meets most airline carry-on requirements at 35L
- Clamshell suitcase-style opening makes packing and access effortless
- Pitch-perfect organization with dedicated compartments for tech, clothes, and accessories
- Scales well from carry-on to checked-bag trips at 45L capacity
- Proven long-term durability — multiple owners report 4-5+ years of heavy use
Cons
- 35L is smaller than competitors like Peak Design 45L or Osprey Sojourn 46
- Less organizational depth than Peak Design for tech-heavy travelers
- Del Dia colorways are random — you can't choose your exact color pattern
- Premium price point is significantly higher than competitors
- 45L may be oversized for ultra-light or weekend travelers
- Heavier than minimalist alternatives
Our take
This is the sweet spot for most travelers — you get the clamshell opening, solid organization, and carry-on compliance without paying Peak Design prices. The fact that it works as a hiking bag too makes it genuinely versatile.
If you can stomach the price, this is the last travel backpack you'll ever buy. Five years of daily use and people still call it 'close to perfect' — that's not marketing, that's earned.
