The seven-litre Trail Proof Drybag is a no-nonsense drybag from Auqapac. Super-rugged construction. Built to last. Made from a tough 500-denier vinyl fabric, the drybag will withstand all the knocks you experience on the trail. It’s really simple to seal – just roll the top down three times. The bright acid green colour (some say yellow) means you can easily spot your gear amongst everyone else's, & it stops the bag from getting quite so hot in the sun.
