DESCRIPTION

With its advanced water-resistance tech, you'll enjoy the lofty, relaxed comfort of the 12-degree down Sea To Summit XtII Sleeping Bag while the advanced technology reduces sweat-induced sogginess. The active 3D NanoShell technology with Nano DWR particles repel condensation from the outside, but the bag's unique siliconized polyester barrier beneath the shell prevents condensed body moisture from soaking back into the down from the inside.
