Currently UnderCool comes in 7 sizes XXS - XXL to fit a wide variety of body shapes and sizes, because “one size fits all” really isn’t true. UnderCool needs to fit your body like a glove to give you the best cooling support. Watch Julia explain how to get the best measurement and figure out the right size. 

 

Sizing Tips:

Sizing for your ThermApparel UnderCool Cooling Vest is really important because it's based on your natural waist. It’s very simple to find your natural waist and you can do it one of two ways.

  • Sizing is based on your natural waist, not your hips or pant size. 
  • Measure against your skin.
  • Avoid using anything that has stretch to it to measure with.
  • Take your measurements in front of a mirror.
  • Make sure your tape measure is level on both sides. 
  • UnderCool needs to fit your body like a glove to give you the best cooling support.
  • If you are in between 2 sizes, order the smaller size.
  • You will wear a size smaller than you think. 

     
  • Stand or sit up nice and tall and bend to the side, where your body naturally creases is your natural waist. Think of the “I'm a Little Teapot” song …”tip me over and pour me out”…right where you crease is where you want to measure.
  • You can find your natural waist in the area below your rib cage but above your belly button. Right in the center part of your abdomen, in the narrower part where your body naturally narrows.

Womens Sizing Guide:

  • Sizing is dependent on natural waist size not bust size.
  • You will wear a smaller size than you think. 

1. Stand or sit up
straight and tall.

2. Bend at both sides.
Where you naturally
bend in your natural
waist.

3. Measure where you bend.
If you don't bend measure below rib cage but above belly button.


Men's Sizing Guide:

  • We recommend ordering a size smaller than your usual T-shirt size.
  • (If you wear a large T-shirt, a medium UnderCool will fit best.)
  • Sizing is dependent on your natural waist size, not hip or belt size
  • You will wear a smaller size than you think. 

1. Stand or sit up
straight and tall.

2. Bend at both sides.
Where you naturally
bend in your natural
waist.

3. Measure where you bend.
If you don't bend measure below rib cage but above belly button.

Don’t Have a Fabric Measuring Tape?

You can measure your waist the same way with a straight ruler and:
String / Yarn
Dental Floss
Shoelace
Charging cord from your phone

When you get your vest try it on with the packs frozen. Ask yourself these questions.

  • Can I feel all 4 cooling packs on my back?
  • If I had one more row of velcro would it fit better?
  • Is there any space between my back and the cooling packs?
  • Are the cooling packs too low?

Should you go a size smaller?

  • If you are going to be using the cooling vest  to run, play tennis or use it for any athletic activity where you are bouncing up and down then yes, order a size smaller
  • If you are between 2 sizes, order the smaller size.
