Introducing the TRI-FIT SiTech Running T-Shirt – your essential running and training companion, designed for optimal comfort and performance.

Tailored for a perfect fit, this tee features thermo-welded seams and hems, ensuring a premium construction that enhances durability. Reflective strips at the front, side, and rear provide visibility during low-light conditions, while laser-cut ventilation adds a breathable element to keep you cool during intense running sessions.

Crafted from a premium lightweight fabric that wicks away sweat, the SiTech Tee prioritizes breathability, comfort, and fit – essential elements for both running and training. Bonded seams contribute to its soft feel against the skin, allowing heat to escape when you're pushing your limits. The tailored finish, technical construction, and elastane for added stretch ensure ease of movement.

Make the TRI-FIT SiTech Running T-Shirt the foundation of your running and training kit. Featherweight and incredibly breathable, you'll feel as comfortable on the last mile as you did on the first. Elevate your running and training experience with this essential tee.


TRI-FIT offer premium quality tri suits, cycle clothing, running gear and athleticwear. Developed by triathletes, made with you in mind.

TRI-FIT was created after founder Dan Evans raced at IRONMAN Dubai 70.3 in 2017. Disappointed with the leading tri suit he wore for the race, he was determined to create something better. Starting with just a pencil and paper, the initial design for the original TRI-FIT EVO tri suit was soon developed into an award-winning tri suit after being put through its paces with extensive testing - covering 1,000km. The EVO soon became a favourite with triathlon experts, earning itself the 220 Triathlon 'Best on Test' award for three consecutive years.

Now based in the UK, TRI-FIT has expanded its product ranges offering next-level kit for triathletes, runners and cyclists alike. The EVO tri suit is now joined by a range of cutting edge suits such as the GEO and the GEO LIGHTNING, offering the balance of aerodynamics, comfort and practicality you need to maximise your performance on race day. Training sessions can be ticked off in style with a range of cyclewear, swimwear and running gear/athleticwear.

Garnering global awards and praise, TRI-FIT is set on becoming the world's premier triathlon clothing brand, fuelled by innovation and a commitment to excellence in the evolving multi-sport landscape. Gear up for your next personal best, with TRI-FIT.
