Katabatic Gear Chisos 40°F Quilt

The Chisos is Katabatic Gear's warm-weather quilt, rated to 40°F (around 4°C) and weighing 490 g — built for three-season trips down to about freezing rather than winter conditions. Duck down fill is treated for hydrophobic performance, helping it resist damp trail conditions and condensation better than untreated down, and as with Katabatic's other quilts, it comes with both a compression stuff sack for the trail and a separate storage sack to keep the down from losing loft when stored at home. As a top quilt it has no insulation underneath and relies on your sleeping pad for warmth from the ground up; included pad attachment straps keep it from sliding off during the night, which matters more with a quilt than with a fully enclosed sleeping bag. At 490 g it's a genuine ultralight option for hikers who pack a pad-and-quilt system, but its 40°F rating means it's not the pick for shoulder-season trips where temperatures drop well below freezing overnight.
