This Givi bag is one of our favorites! There are lots of barrel style drybags on the market, but most have narrow side openings, making it annoying to grab what you need quickly. The Gravel-T has one wide top opening that makes packing easy and works for both small and large amounts. We like that this bag can attach on most bikes with a pair of Rok Straps, making it our go-to bag to bring when renting abroad. Plus it is a great carry-on size for airplanes! Wide enough to fit a helmet, foldable into a smaller dimension, this bag has seen many miles on our bikes.
