QuiltLock System

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.

    Hi Maxim,

    Thanks for your comment on our blog. The Quilt Lock system works on all Sea to Summit sleeping bags (including Ascent Ac I, Ac II and Ac III).

    Feel free to reach out with any other questions you may have.

    Cheers,
    The Sea to Summit Team

    Is the Quilt Lock System on the AscII only or on the AscI also?
