  1. Premium level Gym shirt

    Lee (verified owner)

    What size did you buy? XL

    Ok so bought a Seamless active black gym shirt to see what all the hype was about, got to say I love it. Few reasons, the material feels quality but so light on, I am a 44″ chest so bought the XL and it fits like a glove. It is slightly longer than most which is brilliant as it doesn’t ride up in the gym when doing shoulders or bench press. Quickly my favourite gym shirt so bought a Red one too.
    Can’t wait for new season release as like the products a lot and doing good for the planet. A+

    Really good material, you can tell it’s quality. No chaffing, I like that it’s slightly longer in the body.

  4. Thumbs up from me

    Damien Goddard

    What size did you buy? L

    Great fit, probably the best work out t shirt I currently own. The material used is quality, you can see that no corners have been cut when making this. The no smell quality to this t shirt is also good, worn for a week and so far no body odour on it
    I bought the blue in large.
    Highly recommended 🙌🏼

  7. Great t shirt for running

    Robin Hastings

    What size did you buy? M

    I run in my up t shirt at least 3 times a week and I have to say it’s the most comfy chaff free t shirt ive worn. Nice colours, I bought the blue and really like it. The anti odour part too strangely is true, despite sweating in this t shirt it never has any odour to it, always smells fresh so I’ve been able to wash this less.

  10. Best Gym T shirt 10/10

    J.Ellington

    What size did you buy? M

    This is an amazing t shirt for the gym, the sizing is great, fits nice… it’s a little longer in length than my other t shirts, and I love the sleeves being a little short too, clearly been thought out and designed that way.
    The material is quality, soft and moves with you.the anti odour tech works as I can wear this top weekly without having to wash it so much. It washes nice and keeps its shape.
    This is a very good t shirt for the gym, I imagine for running also as there are no seams that can cause rubbing.

    What size did you buy? L

    I’ve just into playing Padel Tennis and wanted some gear… this t shirt is perfect! Allows full movement, great length, and the anti-odour tech allows me to play in it all week because it doesn’t smell of sweat, crazy! Less washing, play more Padel 👍🏽

  14. Great T shirt for running and gym workouts

    Manny.

    What size did you buy? M

    Quality t shirt, managed to wear it for a week and didn’t have to wash it until the end of the week as it didn’t smell.
    I worn tops like this before but they ended up smelling of metal, this doesn’t though
    Definitely recommended

  15. Nice T

    Pete Travkosky

    What size did you buy? M

    A friend recommended I try this brands gear so I bought this t shirt. This top is amazing, I’m going to buy another, there is nothing like this around. Everything seems to be cheap and made in China, I want quality made gear for the gym that lasts instead of cheap rubbish that falls apart and doesn’t fit properly. This brands ethos I love and it’s certainly the way forward. Yes the t shirt is a bit pricey but it’ll last me so actually it’s a bargain.

    I have the dark blue as it’s unusual, I bought the Medium which is my normal size, a happy customer who will buy from you again for sure. 🙌🏼

  16. Best sports t-shirt

    Tom (verified owner)

    What size did you buy? L

    These are now the only sports T-shirts I wear, both for long distance running and the gym. They are comfortable and durable. As a testament to their quality, my original one has lasted the past year+ better than any of my other sports tops, so I’ve bought more..
