21 Bag - Rain Cover

The fit is spot-on—it snaps over the 21 Bag with zero flapping even in gusty wind, and the fabric feels tough enough to shrug off a full downpour. I've used it on two wet commutes now and everything inside stayed bone dry.

Heavy rain hit during a hike and not a single drop got inside the bag—the fitted shape hugs the 21 Bag so tightly there’s no flapping or gaps to worry about. I’ve used it twice now and the cover stays securely in place even with the bag fully loaded, which is exactly what I needed.

Went on easily and stays put even in a gusty wind, the elastic edge is a nice touch. Kept everything bone dry during my afternoon commute through a sudden downpour.
