Big Agnes Sidewinder SL Sleeping Bag

Ideal for Side Sleepers

Our nylon sleeping bag is meticulously designed for side sleepers. The technical fit and patterned design allow for seamless movement as you roll from one side to the other. Body-mapped insulation optimally distributes warmth and reduces pressure points, ensuring a more restful night's sleep.

Exceptional Warmth and Comfort

The optimized fit and thermally efficient footbox are designed to closely match the shape of your feet when lying on your side. This ensures maximum warmth and comfort. The close-fitting, jacket-style hood keeps insulation near the body while enhancing mobility. Cinch the insulated tube along the upper hood opening to seal out drafts, keeping you snug and warm throughout the night.

Additional Features

Pillow Protection

The unique Pillow Barn is made from stretch mesh material, offering easy access from either side for adjustments. It keeps your pillow securely in place.

Easy Closure

Smooth, quick zips with an anti-snag, locking mechanism and no draft zipper garage provide convenience. The long, ambidextrous zipper remains out of your way during side sleeping.

Storage and Maintenance

Hang dry or store your bag using the exterior loops. The included storage sack and stuff sack make it easy to pack and transport.

Insulation Quality

Our sleep bag features primary fill of 650 fill DownTek, which is water-repellent yet maintains insulating value. It is bluesign® Certified and free from PFOA and PFOS chemicals.
