Big Agnes Sidewinder SL 20°F Mummy Sleeping Bag, Small, 650-Fill DownTek + FireLine ECO Insulation, Side-Sleeper Design, Hooded, Anti-Draft Zipper, Blue
Product Description
Stay warm down to 20°F in the Big Agnes Sidewinder SL, a traditional mummy bag designed for side sleepers. The bag stays in place as you roll over, so you aren't left wrestling with it in the night. It's filled with 650-fill DownTek for warmth, plus FireLine™ ECO synthetic insulation made from post-consumer recycled polyester. The FireLine ECO insulation is placed at the hips and footbox for comfort and warmth and helps minimize pressure points.
A jacket-style hood fits close to the body to keep warmth in the bag, and an internal cordlock adjusts the hood without unzipping. A pillow pocket with stretch mesh is accessible from either side of the interior and keeps your pillow in place. The footbox is shaped to match your natural foot position, and an internal pocket holds a phone or headlamp.
The ambidextrous, anti-draft and anti-snag locking zipper keeps cold air out. The ripstop nylon shell is water repellent without added PFAS, and an exterior loop lets you hang the bag to dry. This is the Small size, with a max user height of 5'6", and it comes with a storage sack and a stuff sack. Please note this product is available online only.
