Mountain Hardwear Switch +20 Sleeping Bag - Long

This Mountain Hardwear® three-season 20° bag's expandable draft tube adds versatility. Soft Thermolite® Extra fill is engineered to provide three-dimensional, springlike loft for superior warmth with minimal weight. Performance-cut mummy shape saves weight by reducing girth at shoulders, hips and lower legs. Quantum Expander allows unparalleled versatility; zip it up for a snug, technical fit or unzip it for eight inches added girth, yielding a roomier bag. Offset quilt construction means no sewn-through seams and no cold spots. Four-panel contoured hood with down-filled face gasket forms around head to seal in heat. Warmth is optimized through differential cut of shell and lining fabrics, allowing adequate room for the insulation to expand to its full loft. Trapezoidal footbox keeps feet from being scrunched and allows insulation to loft fully for added warmth. Insulated draft tube backing two-way, full-length zipper and insulated zipper gusset seal in heat. Anti-snag construction prevents fabric from catching in the zipper; locking sliders keep the zipper in place for customized ventilation. Tie-in loops stabilize Mountain Hardwear 3D Upgrade Liner, sold separately. Comes with stuff sack.
