Filling 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, this bag is made 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.
Rated down to -4F, this bag is best suited for winter camping, high alpine mountaineering, and ski touring
