The 3F UL Gear Exhaustible Compression Stuff Sack is a clever, lightweight dry bag that lets you squash a thick sleeping bag into a much smaller space. Even a bulky bag can fit into a sack smaller than 40 litres.
Push the air out to compress the contents, then slide it into your rucksack. The compression lasts about half an hour before the sleeping bag starts to expand, so your rucksack then holds it in place.
