DESCRIPTION

The Mountain Hardwear 2nd Dimension sleeping bag is a 15F synthetic winter bag. Filled with Polarguard Delta, a durable, lofty continuous filament insulation, the 2nd Dimension retains most of its heat, even when soaked. Shingle construction maximizes loft by overlapping layers of insulation, and an insulated draft collar and multi-panel contoured hood seal in warmth. The Women's 2nd Dimension features a women's mummy cut designed with your body in mind, not some big stinky dude. A trapezoidal, sloped footbox is shaped to accommodate actual human feet, a feature you'll wonder how you ever slept without. Mountain Hardwear's Quantum expander is built right into the 2nd Dimension, letting you transform from a sealed, toasty mummy bag to a spacious, well-ventilated couch-surfing accoutrement.
