This is a standardised guide to give you an idea of what size you will need, however some brands may vary from these conversions.


Many athletes and cyclists struggle with over-heating and sweating whilst training, which can sometimes prevent them from reaching their full potential. Under Armour CoolSwitch garments target this problem with their Moisture Transport System technology, which wicks away sweat efficiently and allows your body and skin to breathe.

Wear the garment in the gym or out on the bike on a warm summer’s day and you’ll find that you can perform for longer and push your limits further. With a flexible fabric woven into the garment, you will see an improvement in mobility in any direction, so when you’re lifting the squat bar to your shoulders, or working up a sweat on the rowing machine in the gym, you have freedom in your movements.

Looks great and is supremely comfortable

Total :


In size Large, I find this to be a body-hugging T-shirt that provides minimal compression, significantly less than say Under Armour's basic (non-CoolSwitch) HeatGear and ArmourVent compression shirts. However, it looks great and is so comfortable I could wear this all day and night in summer. I now have four of these in different colours/patterns. This particular colour is quite striking, and works great as a casual shirt. I got so many compliments from wearing it!
