COOL Mask
The one that caught my eye. Detachable eye cups filled with insulated ceramic beads that stay cold for ~10 minutes (doctor-recommended duration). Store the cups in the freezer for at least 1 hour before use.
Key features:
- Evenly-distributed cooling (not patchy like generic gel masks)
- Near-blackout design with large, wide eye cups
- Infinitely adjustable fit - position cups anywhere on the strap
- Soft, moisture-wicking fabric
- Best for back sleepers (side sleepers should look at PRO)
- Hand wash only
Rated 4.7/5 from 239 reviews. Users report relief for sinus headaches, allergies, eye strain from screens, and migraines.

What Makes Them Different
The modular system is the real differentiator. Eye cups and head straps are mix-and-matchable across the range. The cups sit in cutouts on the strap and slide freely for positioning. No velcro-on-face designs. The strap is 73cm circumference, fully adjustable.
Also sell white noise machines ($75), sleep earplugs ($29), silk pillowcases, blackout stickers, and a red night light.
