The Ultra-Sil™ Dry Day Pack is a waterproof packable daypack, made from siliconized CORDURA® fabric. This ultra-lightweight and foldable day pack resists water and packs into its own tiny stuff sack complete with a carabiner key ring attachment. The seams are double stitched and sealed with high-density PU seam tape. The unique double hypalon roll-top is non-wicking and creates a good seal. The compression lacing system on the front provides secure additional storage.
