Ultralight organization pays major dividends in the backcountry. Which is why we consider our Drawstring Stuff Sacks to be an excellent first step towards dialing in your pack system. With two fabric and six size options to choose from, you&';re sure to find one that works with your gear. If you&';re gearing up for your first overnight backpacking trip, or your thru hike, these will quickly become an essential piece of your pack system - especially when paired with Pods, Roll-Top Stuff Sacks, and a Pillow. Sizing will vary depending on your specific gear, but here&';s a rough outline that we&';ve found helpful in guiding the size selection process. And if you&';re looking at picking up a few sizes, check out our discounted Kits.
