Western Mountaineering

Summer Coupler

Turn Western Mountaineering semi-rectangular bags into a comfortable two-person sleep system by mating it with the Summer Coupler! Its blended fabric has the same feel as the sheets on your bed. Sleeves on the underside hold your insulated pads in place. By nature of its design the Summer Coupler works only with semi-rectangular bags which do not feature hoods. The Summer Coupler mates to the MityLite, Alder, and Ponderosa sleeping bags. (Note: the MityLite uses a 6'6" length Coupler) This is not a waterproof sheet, so a ground cloth is still needed.
