Sea To Summit Alpine ApII Sleeping Bag 5 Degree Down

Even with all its insulating awesomeness, down is pretty much worthless when wet. That's why the Sea To Summit Alpine ApII 5 Degree Down Sleeping Bag uses 3D Nano Shell to stop both external and internal moisture, because even water vapor produced by your body while you sleep can be a dampener. And the miraculous 850 fill Ultra Dry Down repels moisture to retain loft that will keep you warm on extended trips during the coldest months. Baffled construction, cushioned hood, and zipper and neck draft tubes further ensure head to toe comfort.
