Down: 4 Season (+10 and Below)
The North Face Maxwell's Demon MF:
While it might imply a clever play on words, surround down design features four separate radial baffles on the sides, top and bottom to create a uniform and uncompressed loft around the occupant, eliminating cold spots and unwanted shifting. Maxwell's Demon uses 800+ fill European goose down, the highest lofting and warmest down insulation available. Imported from Eastern Europe, the down is processed and tested domestically by The North Face and an independent lab for quality and performance. The bag has a Pertex® Microlight ripstop shell for lightweight, downproof performance with incredible softness and breathability. This quality bag is ideal for backpacking, mountaineering or spending cold winter nights in a spartan cabin or shelter.
