## Description

Dust Water Proof Hypoallergenic

Review: Snug fit and material is strong - These mattress protectors fit my 9” twin mattresses snuggly, which is what I was looking for. The zipper is durable and material is more cloth like than others, so it doesn’t sound like plastic. Will buy again if that time comes!
Review: Great - Does exactly what you want. I’d reccomend.
