Ultra cooling vests from TST Sweden AB are available with either 17 or 21 TEMPTECH elements that absorb heat. They are made of a fast-drying polypropylene fabric that can transfer up to 40 times more moisture than standard polyester. High elasticity provides comfort and a snug fit against the body, increasing moisture wicking. Adjustable elastics at the sides help create a tight, excellent fit, while side extensions make the vest further adaptable to various body types. Permanent TermoFresh antibacterial treatment keeps them odor-free. They are recommended for use tight to the body, with a functional T-shirt between and a covering garment on top. They suit both men and women. www.tst-sweden.com.
