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 Women: 2XS, XS, S, M, L, XL, 2XL **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. ![](https://support.hexoskin.com/hs-fs/hubfs/Taking%20measurements-png.png?width=488&height=309&name=Taking%20measurements-png.png) 1.
