The Wolf Tooth Encase Handlebar Sleeves allow you to easily carry everything you need for a trailside repair, all whilst keeping your tools secure and out-of-the-way. 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.
