Using these Sea to Summit accessory straps is a breeze. For strapping gear to roof racks, just loop the strap around the gear and the rack, then fasten the buckle. To lash dry bags together, wrap the strap around the bags and secure it. When attaching gear to your pack, find a suitable loop or handle on the pack and pass the strap through it before buckling. As for maintenance, keep the straps clean by wiping them with a damp cloth after use. Avoid exposing them to extreme heat or sharp objects that could damage the buckle or the strap itself. Store them in a cool, dry place when not in use to prolong their lifespan.
