Sphere UL 3-Season Sleeping Bag: 14F Down

After a 15-mile day with elevation gains and losses that have left your head spinning, take comfort in the fact that the Mammut Sphere UL 3-Season 14 Degree Down Sleeping Bag will be there once you're ready to set up camp. Through a combination of lightweight fabrics and a high quality down fill, this sleeping bag delivers the comfort you crave when you hit the sack for the night—without the backpack-bog-down weight.

The wind and water-resistant Prolight TX fabric is treated with a DWR coating to protect the down insulation from losing its loft if your bag should come in contact with moisture. Mammut's innovative baffles assume a wave shape, which prevents the bag from slipping and eliminates cold spots in the bag. Mammut's performance hood allows for a full-range of vision when the hood is cinched down, but is also effective at insulating against the cold. A neck collar seals out drafts, while the ergonomic footbox gives your feet room to wiggle while you sleep.
