DESCRIPTION

Adapt to the crazy temperature dives and spikes on your next trip to a yurt or hostel when you sleep in the reversible The North Face Mercurial Liner Bag. This baffled bag adjusts to your desired sleeping temperature through three different insulation options. With the grey baffles on the outside, the bag lets in cool air on warm nights. With the black liner outside and the baffles inside, a cold air barrier keeps your body heat close when you need it. If you sleep with the Mercurial's soft polyester floor as a cover, it can also keep you comfortable on hot nights. The whole bag unzips flat like a blanket, and the inverted stuff sack also functions as a pillow.
