They’re made of Siliconized Cordura, which is one of the lightest and toughest waterproof nylon fabrics available. Now you don’t have to choose between keeping your gear dry and staying light.

Watertight, non-wicking Hypalon roll top closure with stiffener at the top for a better seal
Soft and flexible with a slippery finish for easy packing
All seams are double stitched and tape sealed
Nearly transparent allowing good visibility of the contents

I carry my first aid stuff in this. I've had it for years and it still holds up great. Must buy!
