A customer told me our protector felt warmer than his cotton sheets. He had a point, and here’s why.
To stop dust mites getting through, the fabric has to be very tight, about 5 microns. A normal cotton weave has gaps of around 200 microns, which is how dust mites get in and out.
Tighter fabric means a little less airflow, so there’s always a trade-off between keeping dust mites out and sleeping cool. Ours is lab tested for pore size to get that balance right. If you run hot, a lighter duvet on top helps.
