The North Face

Dolomite 40/4

$79.00 - $89.00

Product Description

Great for occasional warm-weather car camping or short backpacking trips in mild weather, the North Face Dolomite 40-Degree Synthetic Sleeping Bag blends value with ample comfort. The Dolomite is great for casual campers who like a roomy, rather than a restrictive, bag. Its rectangle shape gives you more room than narrower mummy bags, or you can unzip the sleeping bag all the way around the toe box and lay it flat like a blanket.

Though it's designed for casual use, the Dolomite is still packed with technical features that optimize your comfort. Both the outer fabric and lining are water-resistant to protect both you and the bag from heat-robbing moisture. The Heatseeker Eco synthetic insulation is made of 30% recycled material, is highly compressible for easy packing, and more durable than other synthetic insulations. The North Face has accomplished this through a unique dual-layer construction that features an inner layer designed for maximum compression balanced by an outer layer for durability so the insulation doesn't get overly compressed and lose its effectiveness after one season. The top of the sleeping bag is optimized for warmth and durability, and the bottom of the sleeping bag is designed to keep the insulation in place to prevent cold spots. Offset stitching between the layers of insulation helps keep warm air trapped inside.

The Dolomite is outfitted with a convenient, non-snagging two-way zipper (nice if you prefer some fresh air around your feet on warmer nights), and the zipper pull glows in the dark to make unzipping in the middle of the night or before dawn less of a hassle. The sleeping bag compresses down to a 9x17-inch size for easy packing.
