Maybe. The Kriega US25 is right in the middle of the Kriega lineup at 25 Liters. It's not waterproof, but it offers a nice midsize that doesn't feel too big on my frame. I always feel like a little kid if I wear something that's way too big on me. I just bought this last week and will be commuting with her to see how it feels on the bike.
