Using your Synergy Lite Sheets is a breeze. Simply wrap them around your sleeping pad. The matching perimeter loops help keep the sheets in place, especially when used with Therm - a - Rest backpacking quilts. For backpacking duos, use the coupler size to join two pads together. When it comes to maintenance, just throw the sheets in the washing machine for hassle - free cleaning. To make them last longer, avoid sharp objects that could tear the nylon. If your pad gets dirty, clean the sheets regularly to prevent dirt and oils from building up on your pad.
