Organic Cotton Dust Mite Barrier Pillow Protectors and Covers are free from any chemical finishes. These are just extremely tightly woven organic cotton to prevent dust mite eggs from penetrating the covers. These tend to be a little warm as they don't breathe all that well in my opinion. 
I take these wherever I travel. I have a pillow protector and a sleeping sac so that I am not exposed ot whatever may be lurking on the bed I am sleeping on. 
We make these with our tight tooth nylon zippers to keep the mites OUT!!!
Made with 100% Certified Global Organic Textile Standard (GOTS) fabric, organic cotton allergy proof mattress covers. The most natural product available for dust mite protection with 4.5, the tightest microns. 
100% organic means you and your family are not being exposed to any harsh chemicals or toxins. No Chemicals, dyes or any added treatments whatsoever have been used on the covers. Reat assured that dust mites and other allergens cannot pass through these covers to bother you or your family. 
What we do know is that some research shows that allergy-causing molds and fungus are sometimes found on pillows – especially those with synthetic fibers. These microorganisms, as well as dust mites, especially love damp environments
 
The barrier cloth is designed to block dust mite excretion, animal dander, and all sorts of household dust from passing between sleeper and mattress or pillow. It's the most tightly woven natural material we carry, completely prevents airflow, and can help with a lot of other airborne chemicals based on its very small pore size.
It's great to use anywhere you need to prevent dust and allergens from getting into the air; especially pillow protectors and mattress protectors, and also storage bags for bedding 
Laboratory tested to assure that the weave does not separate with use.
Uniquely sanforized to prevent shrinking and maintain the integrity of the pore size through multiple washings and years of use!
Made to Last - All covers are sewn with a double stitch and at least 12 stitches/inch
Heavy gauge nylon zippers
Sewn in the USA
1 year Manufacture Warranty
