The Warwick tee is cut from a single piece of cloth giving a pro-performance fit and eliminating excess fabric whilst optimising freedom of movement. Due to the close cut of the garment if you prefer a more relaxed fit we recommend sizing up one size.

Created for athletes who demand an advantage over the competition, the Warwick tee is engineered to revolutionize your training. The ultra-light, four way stretch Italian fabric is infused with silver chloride which provides complete odour resistance for the lifetime of the garment, ensuring you are stench free no matter how hard you work. Bonded construction throughout minimises friction and reduces excess fabric weight, acting as a second skin against the body and providing exceptional durability. Strategically located laser cut holes map body sweat zones to provide enhanced moisture transfer making this the perfect tee for both indoor and outdoor training. The tailored sleeves with four way stretch capability provide perfect range of movement. Designed to allow you to push the boundaries of performance.

Product details

After months of development and testing, the Warwick long sleeved tee is treated with an advanced Polygiene treatment which guarantees anti-microbial protection for the lifetime of the garment. Polygiene utilises recycled silver to tackle odour producing bacteria at source to keep you stench free. Polygiene does not interfere with the bodies natural bacteria equibirium. Allowing you to pack light and train harder.

Laser cut holes placed in strategically body mapped sweat zones provide impeccable moisture transfer and enhanced drying time allowing you to train longer and harder. Complimented by the unique honeycomb structure of our warp knit fabric which evaporates moisture before it turns to sweat.

The tridimensional structure of our fabric allows for a slim, athletic cut providing an enhanced range of motion in all environments. The Warwick tee has been tailored to an athletes profile, eliminating excess fabric to act as a second skin and providing the aerodynamic benefits of a streamlined cut. We have also incorporated a curved dropped hem and raglan sleeves allowing for the ultimate athletic fit.

  • Love it

    Frederick P - August 29, 2016

    Really comfortable, soft and amazing fit. Love the little hidden pocket for my running gels to slip into and reflective details on back. I worn it for interval train on the first day and it was a second skin and removed sweat in seconds. Always been a wearer of long sleeve tees but will definitely be giving the S/S tee a go too. The white also washes really well!

  • Still smell free!

    Thomas Welder - March 10, 2017

    Bought this top after reading about the brand in the telegraph. Was slightly sceptical at first due to the high price point but was intrigued by the anti-odour treatment. Have had the garment nearly 4 months now and it is completely smell free. Since been back for me.

  • Doesn't smell after 8 weeks

    Frank - March 25, 2017

    Odour technology that actually works! Had for 8 weeks and wear 3 times a week for hard training sessions. It still doesn't smell!

  • Fit's like a glove

    Graham F - April 21, 2017

    I'm 6ft 5 and 18 stone and didn't expect the XL to fit me however it fits like a dream. Normally a XL hangs off me or is too small. Absorbs sweat in seconds and doesn't smell despite sitting in my works locker 5 days at a time!
