Why We Like The Sidewinder SL Sleeping Bag

Trying to find the perfect position to comfortably sleep in our tents just got simpler thanks to Big Agnes's solution for side-sleepers. Working alongside lofty down, this three-season sleeping bag features layers of additional body-mapped synthetic insulation that alleviates pressure points at the hips and feet. The bag's hood is constructed with an integrated pocket that adjusts our pillow's position to our preferred side. Traditional mummy bag features such as a cinched hood opening and water-repellent finish make this specialized sleeping bag ideal for a comfortable night under the stars.

  • Sleeping bag specially designed for those who lay on their side
  • Body-mapping at hips and feet minimize pressure while side-sleeping
  • Feminine mummy fit contours to the body and keeps insulation close
  • 20-degree rating is comfortable for three-season camping trips

Sidewinder SL Women's Sleeping Bags

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. Constructed with features you expect from a traditional mummy bag with additional body mapped insulation to optimize warmth where you need it and minimize pressure points and other ‘side effects’. The Sidewinder SL is a side sleeper’s dream bag with technical features that roll seamlessly from one adventure to the next, and from one side to the other at night. 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.
