Safer, More Efficient than Ice Packs
What is PCM technology? Simply the safest, most efficient personal cooling system yet developed. Unlike water- and gel-based systems, PCM maintains a body-cooling temperature of 65°F—cool enough to keep you comfortable yet not so cold as to cause frostbite. PCM bladder inserts require no freezing, work well in humid conditions, can be worn next to your skin— no layering!—last for hours and completely recharge in about 20 minutes (just place in ice water). Made in the USA.
