- Clover Patch Window Roll for Jeep Wrangler 4 Door 2007 - 2015. The nylon bag that covers the rolled felt is water resistant and coated to keep dust and dirt from getting on the felt and windows. The nylon bag is easily washed and dries in minutes. Jeep owners with hardtops keep their windows in the Window Roll all winter. Photo of Unlimited JK 4 Door. Manufactured by Clover Patch.
