Cooling Pillowcases & Breathable Protectors: Fabric & Weave Comparison

By the CoolingPillows.com Editorial Team Criteria: 10-Point Pillow Spec Framework Sources: 18 Manufacturer-Verified Models

Your outer pillowcase and inner protector sit directly between your skin and the pillow core. Choosing the right fiber—whether moisture-wicking 100% eucalyptus lyocell or high-conductivity 400 GSM polyethylene—determines how the pillow feels on contact and how well it breathes overnight.

How These Models Compare

Compare the plant-based Buffy Breeze Eucalyptus Pillowcases, the high-density Coop Cool Side Pillowcase, and the mesh-gusseted Coop Ultra-Tech Pillow Protector.

Frequently Asked Questions

Should you use fabric softener when washing cooling pillowcases?

No. Fabric softeners and dryer sheets coat lyocell and polyethylene fibers with a waxy film that reduces moisture wicking and surface thermal conductivity.

Does a cooling pillowcase go over or under a pillow protector?

Always place the waterproof breathable protector directly over the pillow first, then slip the cooling pillowcase over the protector so the cooling fabric touches your skin.
