What fabrics are best for regulating body temperature?

The best fabric for temperature regulation can vary by environment and usage. 37.5 Technology is not only embedded in a wide variety of fabric constructions, but also insulations, foams, and laminates to provide tailored thermoregulation in apparel, footwear, bedding and more.

Does 37.5 Technology wash out?

No. 37.5 active particles are permanently embedded at the fiber level, work for the life of the product, and will not wash out during laundering.
