Kryo’s Backpack Ice Zip-up Cooling Vest is flame-resistant, and with its smooth front zipper, is easy to put on and take off.

Made from a single layer of comfortable, flame-resistant, hi-tech blend of 70% Modacrylic, 23% Tencel, and 7% Lycra knit, the fabric is breathable, moisture-wicking, and anti-microbial.  You will wear the vest with the  smooth, comfortable fabric next to your skin, or over a shirt, with the tubing on the outside.
