Grace ★★★★★

I was a little worried the convertible straps would feel flimsy, but the whole 21L bag holds its shape beautifully even when packed for a weekend. The briefcase mode looks completely normal in a work meeting, and I switched it to backpack mode for a long airport walk without having to unpack a thing

Eli C. ★★★★★

The zipper pulls glided so smoothly on my first commute that I actually smiled. Swapping it from briefcase to backpack in about three seconds is a game changer for hopping between subway and office.

Violet V. ★★★★★

The 21L size hits that sweet spot for me—it fits a 14-inch laptop plus a day’s worth of gear without feeling like a suitcase. I’ve been using the briefcase mode for client meetings and the backpack straps for my commute, and the switch takes less than a minute.
