What Our Gearhead® Experts Are Saying:"I reach for the 20-degree Corus when I want real warmth without the confinement of a mummy bag. The footbox seals out drafts, the down lofts fast, and the strap system keeps everything centered on the pad. For colder trips, it’s hard to beat the warmth-to-weight ratio."We count on the Corus 20F Down Quilt when nighttime temperatures drop and we still want the freedom to move naturally through the night. Therm-a-Rest packs the quilt with 650-fill hydrophobic down and uses box-baffled construction to maintain even loft across the entire body, giving us reliable insulation for colder shoulder-season and mild winter conditions. The quilt’s open, comforter-like layout avoids the restrictive feel of a traditional bag while still delivering meaningful warmth as the mercury slides toward 20°F.A precisely shaped footbox can slip over a sleeping pad to eliminate drafts or wrap around our feet for added insulation. Full-perimeter baffles and a snap-closure neckline help maintain warmth when breezes rise, and the removable SynergyLink connectors secure the quilt to our pad without limiting movement. Soft, PFAS-free recycled fabric rounds out the design, pairing comfort with a packable profile that suits extended backcountry travel.
