Our Rain Covers are manufactured with a waterproof, light weight 70 denier Silicon Impregnated Rip Stop Nylon. They are a one-piece construction, so no seams to seal or leak. The small/medium cover is designed to fit either the MS and AS pack models. The medium/large cover is designed to fit either the AS or 45-L packs. The covers have an integrated Velcro pouch to store the cover and will fit nicely in the lower external zippered pocket on the AS and 45-L pack’s.

If you are intending to attach gear (IE. Sleep pad, Tent, etc.) to the bottom attachment loops of the AS model packs, you will need to order the large Rain Cover.
