Bring these back !!

The best. I am slightly on heavier side. These are excellent for someone with a some fat around tummy. Covers nicely. And longer too. . It’s a pity they are not available anymore. These are the best. Breathable best fit. Bring them back.

Great shirt for running

Lightweight and airy, have worn it a couple of times and no chafing so it is a winner for me!

Scratchy tickets

Main ticket stitched on by piece of fabric , but another ticket on the side sewn directly into seam and really scratches ..... go careful trying to cut it off

Additional Product Information


Main fabric: 90.0% Polyethylene Terephtalate, 10.0% Spandex

Why choose a specific t-shirt for running?

Perspiration is a natural reaction that occurs when it is hot and when you are making a physical effort.Do not wear cotton T-shirts because, rather than transferring moisture outward and drying quickly, cotton absorbs body moisture and rapidly cools down the skin. Choosing the right T-shirt will make you more comfortable during your workout, regardless of the duration.

Perspiration wicking

The front panel is made of a fabric that reduces dampness by absorbing and wicking away moisture generated by the body during exercise.The back piece is in mesh for better air flow during the run.


Its rather ample cut and its fluid component let you feel at ease. This T-shirt was adopted by all the testers for its soft and fluid fabric! Try it for yourself!
