High-loft Spirafil 120 insulation makes the Marmot Women's Trestles 15 Sleeping Bag ideal for cold-weather overnight outings. But is not just where the insulation is placed, where its located is also important; Marmot added more insulation in areas where women tend to get chillier and used a wave construction to keep it from shifting around, so you can enjoy a shiver-free night outdoors.

Features:

• DWR coating on the shell keeps morning frost from soaking the synthetic insulation after you spend a night under the stars


• Trapezoidal foot box gives your feet some room to move


• Insulated collar keeps warm air trapped in your bag and closes without a hook-and-loop closure that could snag and rub


• Feely drawcords cut back on middle-of-the-night, half-asleep cord fumbling


• Stash pocket holds your headlamp and other nighttime essentials


• Two-way zippers allow you to vent at the feet or mate the Trestles to another bag
