If you travel through wet climates regularly (or even occasionally) and want to keep your critical pieces of gear dry, look no further. Hand built using DCF11 (1.14 oz/yd2) fabric these Roll-Top Stuff Sacks can quickly become an essential part of any pack system. With four sizes to choose from, for anything from a small food bag to a pack liner, there's no shortage of uses. But keep in mind that these are not a fully sealed closure, or considered a dry bag in the traditional sense. Although when rolled down enough, they're as close as it gets without the added weight.
