A little bit of luxury in a small package. The Thermarest Synergy Coupler Double is a comfortable and breathable double size sheet that will help protect your sleeping mats from dirt and moisture while keeping them close together. Connect a Thermarest double quilt to this sheet to create a luxurious, comfortable sleep system for two.
Thermarest says:
This brushed polyester sheet provides next to skin comfort while joining two mattresses. It includes two sleeves that can accommodate two large (25 x 77 in or 63 x 19 cm) rectangular mats up to 4 inches (10 cm) thick. Equipped with integrated perimeter loops, the Synergy Coupler also mates with our blankets and quilts, so you can create a luxurious double bed in the backcountry.
If your looking for a little extra comfort on your trip, then the Therm-a-Rest Synergy Coupler Double Sheet will give you a little more luxury than just sleeping straight on your mat. It does mean carrying a little extra weight, but it's not much. Other than the comfort it provides, another great reason for using one is that it will protect the top of your mats from dirt and moisture during warm weather. It will also keep the two mats together so you don't find yourself drifting apart in the middle of the night.
