UnderCool 3.0 has a new spandex athletic wear binding that moves with you and your body.

Rounded corners, and gentle curves for better movement, and a new strap design that feels better against your skin.

It has built-in comfort that rivals your yoga pants, you'll forget you have it on. 

ROUNDED CORNERS:

Do you do a lot of bending or sitting? The rounded corners on the belt roll with the punches, all while being more comfortable. Now UnderCool 3.0 fits any activity, even just sitting on the porch.

ATHLETIC WEAR BINDING:

The athletic wear binding moves with you and your body. Now the UnderCool 3.0 fits in that Goldilocks place, not too tight, not too loose, just right. 

No more bulky vests that look like you are in the witness protection program wearing a bulletproof vest. The new incredibly thin, soft straps and athletic wear binding keep the vest against your skin and an invisible look under your clothes. 

STRAPS:

What’s the hold-up? Straps! “pun intended” The new straps are made with a different material and are incredibly thin, soft, and strong. They are also adjustable so you choose how loose or tight you need them. 

UnderCool 3.0 has more adjustability to make sure your vest fits like a glove because a better fit = more cooling power. With the upgrades, our sizing has changed. You will now wear a size similar to your t-shirt size. Check out the new sizing chart before ordering. 

MORE VELCRO:

Need it tighter for exercise? Need it looser after a big cookout? No problem; there are now 3 sections of hook & loop, not just 2.

UnderCool 3.0 will fit you like a glove and move with your body making it the perfect fit. Now you can adjust it to be YOUR UnderCool. 

Cooling Packs changes just got easier. The new easy-to-use Quick Change Pockets make UnderCool 3.0 the easiest vest to keep you going.

QUICK CHANGE POCKETS:

The opening for the pockets is now on the outside, not the inside. Like a race car pit stop, you can be in and out in mere seconds, ready to go for more fun.

The whole point of a cooling vest is cooling, right? It’s not sweat that cools the body. It’s the evaporation of sweat. That’s why we added more breathable mesh. Cooling your core gives you time and energy for better performance and faster recovery while fighting fatigue and cog fog. UnderCool 3.0 is made to enhance your body's cooling power by keeping your core cool with our lightweight, signature Cooling Packs while still having airflow with more breathable mesh. 

MORE BREATHABLE MESH:

More breathable mesh = more airflow. More airflow  = more cooling and unlike the other cooling vests on the market you don't have to wear UnderCool 3.0 over a shirt. Safely wear it right next to your skin for powerful cooling and airflow. 

ThermApparel SIGNATURE LIGHTWEIGHT COOLING PACKS:

Our Cooling Packs are designed to start melting and refreezing at 70˚F/21˚C. They won't burn your skin or get you wet like ice or gel packs. They keep you cool in humid and dry climates without being wet, bulky, or dangerous to your skin. Bonus–They refreeze in ice water in 30 min. ​​​​
