Not All Cooling Garments Are Created Equal

ThermApparel is the only cooling brand utilizing 4-way stretch material across all products to ensure cooling packs conform to your body with the most possible contact. Allowing for faster, more efficient heat transfer.

Thoughtful design and precise USA manufacturing gives you the best fit, most comfort and durability for your needs.

Cooling for Any Activity in Any Climate

Our non-toxic, biobased pcm pulls heat away from your body no matter the humidity or temperature, unlike evaporative products which lose efficiency in humidity.

Our lightweight and flexible design allows you to perform most activies without being encumbered.

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

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!
