Don't cancel your next overnight adventure because the forecast calls for a bit of rain: bring the Marmot Trestles 15 Long sleeping bag for men, 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 exploring, zip up the full-length two-way zipper, pull on the 3D hood, and give your feet optimal rest in the spacious footbox. Its top wave construction and bottom blanket construction provide an unbeatable blend of warmth and comfort, along with reinforced insulation in strategic areas. If the interior gets too stuffy, use the secondary fold-down zipper for some air. Clearly, the Trestles 15 Long is made for adventurers.
