Sea To Summit McIII Sleeping Bag: 28 Degree Down

Phrases like 'incredibly light,' 'ultra-breathable,' and 'insanely packable' get thrown around a lot, but we have a difficult time not using them when describing the Sea To Summit McIII 28 Degree Down Sleeping Bag. Heavy-duty down with feather-light materials keep you warm, while the 2D NanoShell keeps moisture away from the down and lets water vapor escape. The whole toasty package compresses down until it's around 3.5 liters, leaving you lots of room in your pack for some extra caloric goodness.
