Plunging temps don't stop when you're on the trail or car camping—that's why the Marmot Men's Never Summer Down Sleeping Bag is a must-have for staying warm and dry, (0°F/-18°C). It packs tightly into a backpack for long treks, and 650-fill-power down helps prevent heat loss on cold winter nights. Looking for more room? Open the footbox for space to stretch or zip it up for extra warmth. Unzip the extended zipper flaps on extra-cold nights for blanket-like coverage.
