Specifically designed for those who sleep on their sides, the patent pending Sidewinder Series was engineered to ensure warmth, comfort, and ease of use no matter which side you’re on. Our Women’s specific bags differ in shape and fill weight with a less drastic taper from shoulders, to hips, to feet - reducing cold spots and creating more warmth where it counts.

Perfect for side sleepers!

Love this concept for side sleepers like me - no more uncomfortable zip to lie on. Plus when lying on my back to read, or sitting up to cook/eat in the tent it's more practical to open up the bag for getting my arms out.
