UnderCool FAQs
Unisex Sizing Guide:

- 1 set of cooling packs
What is UnderCool?
UnderCool is a lightweight garment designed to keep you cool and comfortable in any situation. The unisex design can be worn under virtually anything. Unlike other cooling garments, you can wear UnderCool directly on your skin. With UnderCool you can stay cool and look it too!
How Does UnderCool Work?
UnderCool uses multiple layers to maximize cooling effect and duration. The garment is made of comfortable wicking fabric to keep you cool and dry and features mesh panels for maximum breathability. The lightweight and flexible phase change material packs are reusable cooling materials for the garment. UnderCool features velcro for easy on and off application and adjustable straps for the best fit.
What is Phase Change Material (PCM)?
Phase change material (PCM) is a category used to describe a wide variety of materials capable of storing and releasing large amounts of energy during the melting/freezing process.
How Do PCMs Work?
PCMs are substances that absorb and release thermal energy during the process of melting and freezing. In the case of UnderCool, the PCM slowly absorbs your heat over time to keep you cool and comfortable, even in humid environments!
Are PCMs Safe?
Not all PCMs are created equal. ThermApparel uses a PCM which is USDA certified bio-based. That means no dangerous oils or hard to clean paraffin waxes.
What Does USDA Certified Bio-Based Mean?
Back in 2002, the United States Department of Agriculture (USDA) initiated the USDA BioPreferred® program as part of the Farm Bill. The Program is an accreditation for products with demonstrated biobased content – meaning the ingredients come from renewable biological sources.
The USDA Certified Biobased product label actually lists the percentage of biobased content in each product. The move was made to help consumers identify biobased products and increase the demand for renewable commodities.
So why buy biobased? There are a lot of good reasons why the USDA is promoting biobased products: Biobased products replace the need for many petroleum-based products, reducing our dependence on fossil fuels. By reducing the need for mining and burning of fossil carbon, we can avoid the release of new carbon into the atmosphere and help control climate change.
How Long Does it Take to Recharge the Cooling Packs?
The cooling packs will freeze in any environment under 70˚F / 21˚C.
- Using water with ice(bottom of a cooler): 20 minutes
- Freezer: 45 minutes in the Freezer (with or without vest)
- Refrigerator: 60 minutes
- If left on a cold surface in a cold room under 70˚F / 21˚C: 10-12 hours
Please note all recharging times are approximate.
Can I take UnderCool On a Plane?
Possibly. By being prepared with the correct TSA guidelines ahead of time. Read the tips and guidelines we have put together for you.

Jenna –
This is life changing. First, it doesn’t make me cold, it cools me down. It helps me not get nauseous and overheated while outside and even inside (no a/c at home). Noone even noticed I was wearing it when I went to a BBQ. It fits tight on my body, but very comfortable and stretchy material. I was worried about my insurance not paying for it. But, I followed the steps in the FAQ section and got all the paperwork from my doctor and proof of it being a DME from lupus health shop and it got approved. Thank you so much!
Jamilla –
This is perfect! I never write reviews. Even if my insurance didn’t cover it, I’d still invest in this. Finally something that fits comfortable and helps keep my body from overheating. All I do is put the icepacks in a small cooler and let it freeze up so I can use this all day. It doesnt burn your skin, it feels like yoga pant material and is very breathable, not adding to the hot day. Kept me cool and comfortable at a concert. No one noticed I was wearin it!
