The Featherweight Raincovers are a compact and excellent addition to any pack. Like the reversible covers, these are designed to cover either the entire pack and a weapon that's being carried, or just the pack itself so that you can pull a gun from the scabbard. High quality polyurethane- coated nylon. Available in UNICAM Digital Weight: 4 oz. Choose the narrower G1RC for G-series packs, or the wider J1RC for J-series packs.
