Trying to squish a bulky sleeping bag or puffy jacket into your backpack? This REDCAMP compression sack is your best friend. It’s the Medium (M) size, holding about 17 liters, with dimensions around 8.6 inches in diameter by 18.1 inches tall (22x46 cm). It’s made from lightweight, durable, and water-resistant ripstop nylon, so it can take some abuse. The magic is in the four adjustable compression straps on the sides – you pack your gear in, close the roll-top, then tighten those straps to squeeze out all the air and shrink the bundle down to a much smaller size. This saves a ton of space in your pack. It also has a handy zippered pocket on the top lid for small items you need to grab quickly (like a headlamp or snacks), and a comfortable carry handle on the bottom. Perfect for backpacking, camping, or even storing seasonal bedding at home. Available in orange (high visibility is good!) and other sizes. REDCAMP offers a 365-day warranty. A simple, effective piece of gear that every backpacker should have.
