Determining Hexoskin Shirt size

In the Hexoskin Shirt, cardiac and respiratory sensors are embedded at the chest and belly button level. The Shirt was designed to be snug fit as the sensors need to be close to the body to measure and collect good data quality. It is thus important to take the measurements at those specific locations in order to pick the proper Shirt size. 

Hexoskin Shirts come in different sizes for Men, Women, and Juniors:

Men: 2XS, XS, S, M, L, XL, 2XL, 3XL, 4XL

Women: 2XS, XS, S, M, L, XL, 2XL, 3XL*, 4XL*

Juniors: 2XS, XS, S, M, L, XL

* These sizes are only available for the Hexoskin ProShirt.


To take your measurements properly, proceed as follows:

Stand up straight, preferably in front of a full-length mirror, and take all measurements by applying the measuring tape directly against your body. Make sure the tape is parallel to the ground and keep your arms along your body as much as possible.

  1. Position a measuring tape around your rib cage, under your pectoral muscles
  2. Breathe out and note your Thorax measurement
  3. Repeat steps 1-2 at the level of your Navel**
  4. To determine your size please, refer to our sizing guide.

** For women, an additional measurement can be taken at chest level (i.e. fullest part of the chest)
