Men's Traditional Mummy bags are built for performance. In our first diversion from the Big Agnes System since we started 12 years ago, we are proud to introduce the most technical old-school sleeping bags ever! These bags are insulated with DownTek(TM) water repellent down and constructed with Insotect Flow(TM) patented technology. Their mummy shape and lightweight materials will get you wherever you want to go, fast and dry. Features:Traditional mummy shaped bags without the pad sleeve 70"/178cm YKK #8 zipper Interior fabric loops for sleeping bag liners Mate together left and right zip bags Mesh storage sack & nylon stuff sack No-draft collar seals around neck to keep cold air from sneaking in No-draft wedge insulates the connection between the bag and pad No-draft zipper tube insulates along the length of the zipper Flow(TM) Construction: Insotect Flow(TM) 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. LEFT OR RIGHT ZIPPER? When you are in the bag, on your back, the right zip will be on your right side, left zip on your left side regular/up to 6' long/up to 6'6" Pad Size any any Color blue/gray blue/gray Fill Type 700 DownTek(TM) 700 DownTek(TM) Fill Weight 11.5oz 13oz Bag Weight 1lb 14oz 2lb 14oz Shoulder Girth 60" 62" Hip Girth 54" 56" Foot Girth 36" 38" Stuff Sack Size M-8"x17.5" M-8"x17.5" Compressed Bag Size 7"x9" 8"x8"
