Sea To Summit ApIII Sleeping Bag: -4 Degree Down

Nothing takes the fire out of your engines more than trying to sleep in a soggy down bag, so Sea To Summit designed the ApIII Sleeping Bag to block outside moisture and prevent condensation build-up during long stays at base camp. To achieve this feat, Sea to Summit made this bag with lightweight, breathable outer 3D NanoShell fabric with a Nano-DWR coating and a silicone condensation barrier just inside the shell fabric to expel any moisture that your body creates during the night.
