Wolf Tooth EnCase System Storage Sleeves. Easily carry everything you need for trailside repair in a secure out-of-the-way location. The engineered design and rubber material of the sleeves keeps everything securely in place prevents the multi-tools from rattling and protects the multi-tools from dirt and moisture while still being simple to remove without tools. Extra space was created in the bar plugs to store a presta-to-schrader adapter and valve core or a master link for support on the trail.
