Eva ★★★★★

The removable rolltop bag is genius for day trips once you've dropped your main bag at the hotel. And it still fits in the overhead bin even packed to 40L, which I honestly didn't believe until I tried it.

Sofia ★★★★★

Took this on a two-week trip with just carry-on and never once got stopped at the gate. The 40L size is the sweet spot, and I ended up using the detachable rolltop bag as a daypack for hikes. Zippers feel sturdy too.

George ★★★★★

Took this on a week-long trip with only carry-on and it swallowed everything I needed. The 40L size squeaks right under the airline limit, and I loved being able to detach the rolltop bag for day hikes once I got there.
