Pillow Lock™ System

The Pillow Lock™ System comprises of self-adhesive hook-and-loop patches which are supplied with all Sea to Summit sleeping mats (as of Spring 2019),

Attached to your sleeping mat, these patches secure your pillow and prevent it slipping – yet they will not snag on clothing or other lightweight fabrics.

All Sea to Summit Pillows (as of Spring 2019) are compatible with this system. Existing pillows can be made Pillow Lock™ compatible by adding an Aeros Pillow Case.

    G’Day Frank,

    Thanks for bringing this to our attention. We have called the Bellingham REI store to explain the hook-and-loop patches supplied with all Sea to Summit sleeping mats and to let them know how these patches locate onto the sleeping mats to secure 2019 Aeros Pillows.

    Please email us at and let us know your full shipping address – we’ll be happy to send you a set of the hook-and-loop patches with instructions for securing them.

    I just bought comfort light insulated (green) sleeping pad and an Aeros Premium pillow. The staff at REI Bellingham did not know how they attached together and tried to make the valves fit into one another and said that was how it was suppose to work. When I got home it was clear that that was NOT how it worked and then I looked online and there should have been “hook and loop” fasteners with the pad but there were not. What is the issue does this pad not come with them? Did someone in the store remove them from the packaging? I appeared not to have been opened and the patch kit was with the informational material. Thanks for your insights.

    G’Day PM –

    The 2019 Aeros Pillows use a different external fabric which will stick to the Pillow Lock patches (the 2018 pillows will not stick). Email us at and let us know where you are located – we’ll put you in touch with someone who can help you further.

    I have 2018 SEA TO SUMMIT Aeros Premium Pillow Large green – APILPREMLGGN, will it work with the pillow lock of Etherlite XT mat (without any added pillow case)? Are Aeros Premium Pillows from 2018 any different from those of 2019?

    G’Day Ben -

    Sorry to learn that your new Comfort Light mat did not have the Pillow Lock self-adhesive patches in the packaging. Shoot us an email at with a copy of your receipt and your shipping address and we’ll get a set of patches on their way to you.
