ThermApparel’s environmental difference
ThermApparel’s environmental difference
ThermApparel uses a bio-based PCM which is non-toxic and bio-degradable. A great improvement over older technologies like toxic paraffin PCM and salt hydrate gels.
All plastics used to encapsulate cooling materials will eventually wear out. Unlike our competitors, ThermApparel offers a recycling program to easily and safely replace worn-out Cooling Packs.
Easy to use
Easy to use
No batteries, no hoses, no loud fans, and no need to “plump” like gels or leave in the freezer for hours to recharge.
Our cooling packs are designed to be easy and eliminate planning.
Recharge
put cooling packs in fridge, freezer, or ice water to recharge in 30-60 minutes.
Relax
insert charged cooling packs into the garments pockets and use for 1-4 hours depending on pack type.
Repeat
enjoy cooling relief thousands of times for up to 3 years.
because our recharge times are faster than melting times buying a second set of packs, means you will never run out of cooling!
