Using the same tough material as our Wet-Sacks, our new Dry-Sacks are designed for the opposite purpose – rather than keeping the wet in, these keep the wet out! All three models feature a stiffened, reinforced top band, which can be rolled down and clipped together to provide a 100% waterproof, airtight bag. Fitted with D-rings each side onto which are clipped adjustable webbing carry-straps – a single shoulder strap on the small model and twin straps in the medium and large, so they can be worn as a rucksack. The smallest 10 litre model is ideal for valuables, plus a jacket or sweater. The medium 30 litre model makes a great stuff bag, while the large 60 litre model will swallow pretty much anything
