Sidewinder SL 35 (650 DownTek)

Product Information

The Big Agnes Sidewinder SL 35 (650 DownTek) sleeping bag is a game-changer if you’re a side sleeper. It’s specifically designed to contour to your natural sleeping position, allowing you to roll freely without getting tangled or creating cold spots, a common frustration with traditional mummy bags. This bag combines lofty warmth with thoughtful ergonomics for a truly comfortable night under the stars.

It features a unique jacket-style hood and a central zipper, ensuring mobility and easy adjustments, while the body-mapped insulation strategically places warmth where side sleepers need it most, like hips and feet, mitigating pressure points. This blend of warmth and freedom makes it ideal for 3-season camping and backpacking, particularly for those who toss and turn.
