We build our water resistant Backpack Cover out of 70 denier IX camo. The IX fabric is PU coated on the inside and DWR coated on the outside for the best waterproofing. We have 5 tension adjusters to keep your cover in place and the water out. Each corner of the cover can adjust in or out depending on how full your backpack is. There is one main cord you can adjust the tension of the cover going over your backpack. Proudly Made in the U.S.A.
