Much more than meets the eye!  With virtually endless applications, these incredibly light, super tough, food-grade drybags are certified waterproof beyond 200ft (no, that’s not a typo), are totally dust/sand proof and allow you to see and use electronics straight through the bag.  They are cheap and can be completely recycled when eventually worn out.  They also make a great compression dry bag for down or other water-sensitive items.  As a bonus, the OPSAK range is completely odour-proof (even to animals) so make great camp or human waste disposal bags. 

 The longer you use OPSAK bags, the more you’ll love them.
