How to Use a Shower Cap Pack Cover for Rain Protection

Quick answer

To use a Shower Cap Pack Cover, simply stretch the elastic hem over your backpack's top and sides, then tuck any excess under the pack for a snug, stormproof fit.

How to fit and use your Shower Cap Pack Cover

1. 1. Unpack and shake out the cover: Remove the cover from its stow pouch and give it a firm shake to open the elastic hem fully. Hold it by the hem with both hands, opening facing downward. If the cover is twisted, the elastic won't seat evenly — untwist it before draping.
2. 2. Drape over the top of your packed backpack: Place the center of the cover on the top panel of your pack, then stretch the elastic hem down over the sides. The cover should reach just below the pack's top compression strap or the top of the main compartment. Don't pull the cover all the way to the bottom of the pack — it only needs to cover the main body and lid, not the sleeping bag compartment.
3. 3. Center and adjust the elastic hem: Walk around the pack and check that the elastic band sits at the same height on all four sides. If one side rides higher, gently pull the cover downward on that side until the hem is level. A crooked cover creates a gap where rain can enter — take an extra 10 seconds to center it.
4. 4. Tuck any loose fabric under the pack: If your pack is smaller or the cover seems baggy, lift the pack slightly and tuck the excess cover fabric under the pack's bottom. The elastic will hold it in place. For a frameless pack, avoid tucking so much that the cover pulls the pack out of shape.
5. 5. Secure compression straps over the cover (optional): If your pack has side or top compression straps, route them outside the cover and cinch them snug. This keeps the cover pressed against the pack and prevents wind from lifting it. Do not cinch straps so tight that they tear the cover fabric — hand-tight is enough.
6. 6. Stow the cover when not in use: When the rain stops, remove the cover, shake off excess water, and stuff it back into its stow pouch. Store the pouch in an outside pocket or inside your pack for quick access. Never pack a wet cover inside your sleeping bag or clothing — it will transfer moisture. Let it air out at camp if possible.
