Warmth, comfort, and versatility all rolled up into a solid bag.

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