Don't cancel your next overnight adventure because of a little rain in the forecast: bring the Trestles 15 Men's Sleeping Bag from Marmot, designed to perform in cold and wet conditions. The SpiraFil™ insulation will keep you warm even when moisture is present. After a long day of exploration, zip up the full-length two-way zipper, pull on the 3D hood, and give your feet optimal rest in the spacious footbox. Its wave construction top and blanket construction bottom offer an unbeatable mix of warmth and comfort, with reinforced insulation in strategic areas. If the inside gets too stuffy, use the fold-down secondary zipper for some air. Clearly, the Trestles 15 is made for adventurers.
