What does QuiltLock mean and how does it work?

The QuiltLock system uses the snap locks located at the shoulder and foot end of Sea to Summit sleeping bags plus the quilt footbox / quilt straps to secure a quilt to the sleeping bag. This adds thermal performance and versatility to your sleep system: your integrated quilt now works for ultralight summer adventures and turns your three-season bag into a four-season sleep system.

All Sea to Summit sleeping bags and Sea to Summit Ember, Cinder and Glow quilts can be connected together to create a sleep system which adds a season to the thermal performance of the sleeping bag.

If you have an older sleeping bag which does not have the snaps at the foot end, secure the quilt under the footbox of your sleeping bag using the strap that you normally use to secure the quilt to your sleeping mat.
