Big Agnes Heart Mountain 30 SL Sleeping Bag 800 Down

The Big Agnes Heart Mountain SL Sleeping Bag is filled with light, compressible 800 fill goose down and weighs only 2 lbs. Like all Big Agnes sleeping bags, the Heart Mountain has an integrated pad sleeve so you never roll of your pad again. Removing the insulation on the bottom also reduces weight since compressed down has no insulating effect. We recommend the Big Agnes Insulated Air Core Pad for use with the Heart Mountain sleeping bag.

• Flow™ Construction: Insotect Flow™ is a flow-optimized insulation system that delivers uniform heat distribution and natural body contouring through its revolutionary baffle design. Flow Construction eliminates lateral and vertical down shifting by using vertical chambers with Flow Gates to regulate fill positioning and density. Strategically placed Flow Gates minimize vertical down shifting while vertical chambers minimize lateral shifting. With continuous vertical Flow chambers in place of traditional side seams, Flow bags eliminate potential cold spots which can occur with side seams. Vertical baffles now flow with your body for more rapid and uniform body heat distribution.
