Glacier Tek’s Concealable RPCM Cooling Vest surprised us in our original 2011 testing with strong numbers across the board. Since then, other manufacturers have been gaining ground and we've tested far more vests, and while the RPCM vest still gets accolades for all around performance, its comfort with some body types is questionable. Its poncho design with two large velcro bands is easy to handle—even with bumbly MS fingers—and is quick to cinch tight to the chest. Since the packs are phase change, they recharge quickly in ice water, great if you are on the go, and stay blissfully dry in all levels of humidity. Expect a reliable 4+ hours of cooling in optimal conditions (room temperatures), among the longest lasting cooling power of vests tested.
Although the Glacier Tek is called a “concealable” vest, it’s really not unless you only frequent darkened movie theaters, dimly lit nightclubs, and conventions for the seeing impaired. We've also learned from feedback that women with larger busts do not find the vest pleasant to wear. Additionally, these types of larger phase change vests (like the 500g Polar58) don’t feel terribly comfortable on your back when you are reclined, seated, or doing those darn hamstring bridge exercises. Even so, this vest remains an ActiveMSers favorite for MS heat relief, with reliable, long-lasting cooling that's not too cold.
