All sleepers enjoy dry sheets. And they're a necessity for humid climates, 'hot flashes' or 'night sweats' associated with pregnancy or post-menopause. Under these conditions, cool sheets aren't adequate because cool sheets still get wet.
Why is relief for sweaty sleep so hard to find? Well, most sheets are made from cotton, a fiber that absorbs water and water vapor (perspiration). ("Easy Breezy", an ultra-lightweight cotton that can't hold much water, is the sole cotton sheet tested 'acceptable' for dryness.) Microfiber sheets are made from polyester, which is a poor conductor of moisture and therefore unsatisfactory.
A new trend is to re-purpose athletic fabrics for sheets. Most of these high-performance fabrics are either too heavy or too textured for sheets. Our rare "No Sweat!" sheets are rayon/nylon and triple-patented for superior smoothness and tested best for their ability to diffuse moisture. They're also ultra-hygienic, non-wrinkling and easy-care.
