Known by Volcanologists the world over you'd think this Puma MF was filled with high lofting lava!

9" of loft, 36 oz. of 850+ fill power down, two densely packed Interlocking Draft Tubes and a full down filled collar will keep you in the ring of fire till 25 below zero.

Its VBlock Side Baffle provides phenomenal down control, so necessary in a bag with this much loft. You get a 64" shoulder girth so that there's even room for layering. The MicroLite XP shell has superior breathability while being extremely water resistant.

This bundle of warmth weighs in at just 3 lb. 7 oz. total weight.
