The material used Excel Dry Triplex 300 is a super light three-layer shell used for waterproof jackets and bivouacs. The efficient non-porous PEBA membrane prevents moisture from outside entering the insulation and at the same time removes body moisture from the product. The DWR finish increases water resistance and the mini ripstop structure makes it highly abrasion resistant and increases tear protection.
