Trestles 20 Semi Rec Sleeping Bag: 20 Degree Spirafil

The Marmot Trestles 20F Semi Rec Sleeping Bag uses Wave Construction to make sure you stay warm and dry in wet conditions. An extra layer of Spirafil synthetic insulation covers an overlapping wave of insulation shingles, eliminating heat escape and making it very difficult for moisture to work its way in. A snagless draft tube blocks air from passing through the zipper, and easy-grab draw cords let you make hood adjustments in the middle of the night without having to turn your headlamp on. Two-way zipper sliders allow you to zip two sleeping bags togetherfor survival purposes, of course.
