Therm-a-Rest Corus™ 32F/0C Quilt

The Corus 32F/0C is the milder-rated sibling in Therm-a-Rest's Corus quilt line, with a manufacturer comfort rating of 5 °C and a limit of 0 °C — built for summer nights and the warmer end of three-season use rather than the shoulder-season range of the 20F/-6C version. It uses the same 650-fill hydrophobic duck down but less of it, 340 g against a total weight of 560 g, nearly 170 g lighter than the colder model. The shell is 100% recycled 20D nylon ripstop with a DWR finish, and the down is RDS-certified with a PFC-free construction — details that matter to sustainability-minded buyers. Horizontal box-baffles bias down distribution toward the top of the quilt, roughly 60/40, since a quilt user's underside is typically insulated by the sleeping pad instead. A trapezoidal footbox and pad-attachment loops close off draft points as with the whole Corus line. Packed size drops to 25 x 17 cm, and at 560 g it suits summer backpacking and warm three-season trips where a full-weight quilt would be overkill.
