What Our Gearhead® Experts Are Saying:"I have been a side-sleeper my whole life and the Big Agnes Sidewinder SL Sleeping Bag is the first bag that actually accommodates how I naturally sleep rather than fighting me all night. The body-mapped ECO insulation at the hips and feet eliminates the pressure points that wake me up in a traditional mummy bag, and the integrated hood pocket keeps my pillow exactly where I put it no matter how much I move around during the night."Most sleeping bags were designed for people who sleep on their back, and if you are a side-sleeper you have spent enough nights on the trail waking up from hip pressure and a pillow that has drifted halfway across the tent to know it. The Big Agnes Sidewinder SL Sleeping Bag was built specifically to fix that, engineering a three-season mummy bag around the way side-sleepers actually move and rest through the night.Body-mapped ECO insulation made from 100% recycled polyester is layered at the hips and feet where pressure accumulates most for a side-sleeper, relieving the contact points that interrupt sleep and leave you stiff in the morning. The integrated hood pocket keeps your pillow anchored at your preferred side so it is there when you reach for it at two in the morning. Primary insulation is 650-fill DownTek with a water-repellent coating that maintains loft in damp conditions, and the feminine mummy fit contours closely to the body to keep warmth right where you need it on nights down to 20 degrees. A full-length anti-snag locking zipper opens and closes smoothly, and the nylon ripstop shell and polyester taffeta lining both carry a water-repellent finish for added protection against tent condensation and moisture.
