Advantages

This sleeping bag provides a perfect balance of weight, warmth, and packability. The THERMOLITE® synthetic insulation retains heat even when damp, while the DWR-treated nylon shell resists moisture. The WaveLoft™ construction eliminates cold spots and maximizes loft. The tapered rectangular shape offers more room than a mummy bag without sacrificing thermal efficiency.
