The Montbell Seamless Alpine Burrow Bag #3 combines low weight, compact pack size and dependable synthetic insulation for hiking and camping. Its seamless outer construction helps the insulation maintain its loft and trap warm air, while reducing heat loss through seams and the formation of cold spots.

Montbell's proprietary Exceloft® insulation combines fibers of different thicknesses to provide reliable warmth. It retains its insulating performance when damp, dries quickly and recovers its loft after repeated compression. The material is also washable, making the sleeping bag easy to care for.

The Spiral Stretch™ system uses diagonally arranged fabric and stitching to provide natural stretch that follows your movements without adding unnecessary weight. The inner construction offers up to 114% stretch, while the two-layer insulation helps distribute warmth evenly.

The sleeping bag features a right-hand zipper measuring 150 cm. A specially designed zipper slider component helps reduce fabric snagging when opening and closing the zipper. A stuff sack is included for storage and transport.
