Ver-Tex 6.1 Mattress Protector now has a cool feeling when touched, deflecting heat and wicking moisture away two and a half times faster, than the original Ver-Tex 6.0. The fabric construction is contoured and channeled, and it provides ambient air ventilation, during the night for improved sleep. A dynamically reacting surface, to sleeper motion, the protector is flexible, for the utmost, comfort level. Additionally, it keeps sleeper's dry, with an invisible and waterproof barrier back. No need to fear interruption of the comfort level of the mattress, as it enhances those conforming aspects, while it reduces any problems regarding heat. The Ver-Tex 6.1 circumference has a Powerband® which enables a fit for the mattress that is secure, and grips well, so it is foolproof, for adjustable bases. Fitting mattress profiles up to 18", this mattress protector does not bunch up underneath the sheets, due to its high-stretch skirting, is odor resistant, and may be machine washed in high-efficiency machines.
