Eberlestock Reversible Rain Covers are a compact and excellent addition to any pack. Eberlestock knows how important it is to keep your stuff dry when you're out in the weather, so they've made covers that will give you every option. These are designed to cover either the entire pack and a weapon that is being carried, or just the pack itself so that you can pull a gun from the scabbard. The blaze orange side is a great way to flag your pack if you remove it to make a stalk.
