Attachment System
The backbone of our quilt style sleeping bags is our patented Cord Clip attachment system. The beauty of this design is its simplicity. All our bags feature our Cord Clips, and come with 2mm cord for attaching the sleeping bag to the pad. Simply tie the cords around the pad, and attach your bag! Got a Backpacking Light® Torsolight™ pad? Therm-A-Rest® NeoAir™? No problem! This system works easily with any sleeping pad.
sleep systems
Our Cord Clips feature two attachment points for maximum versatility. The first attachment position allows the clip to slide freely on the cord. For warm weather this gives you the most freedom of movement. As the temperature drops, clipping into the second position allows you to lock the bag in place on the cord. In this position you can control the girth of the bag, and are able to set the bag to overlap your pad to lock out drafts. Even with the Cord Clip in this position, adjustment along the cord is easily accomplished by lifting the Cord Clip vertically. With the Cord Clip held vertically it slides easily along the cord. Returning the clip to its horizontal position locks the Cord Clip in place along the cord. This allows you to adjust the interior volume of the sleeping bag, as well as adjust the bags position on top of the sleeping pad. Secondary clips help seal out drafts when the temperature really drops.
This unique design offers significant advantages. The ability to attach your sleeping bag to the top of the pad, as well as the ability to easily adjust the girth/volume of the bag, allows you to optimize the position of the bag depending on your sleep position, and the level of warmth you need from your bag. In warm weather you have much more room than you are used to in a mummy bag. In cold weather just close the bag in around you for maximum warmth.
