Introducing the TRI-FIT SiTech Women's Running Tee – a high-performance and technically sophisticated T-shirt delivering the light, airy feeling of a singlet.

Designed for running, this tee features a four-way stretch mesh fabric on the arms and shoulders, ensuring you stay cool and dry during the toughest training sessions. It strikes the perfect balance between providing coverage and the stylish look of a tee. The body is constructed from an ultra-soft, sweat-wicking, lightweight fabric with thermo-welded seams, delivering a comfortable feel against the skin.

The tailored finish, technical construction, and stretch of the TRI-FIT SiTech Women's Running T-Shirt guarantee ease of movement, making it an ideal choice for running. Reflective panels at the front, side, and rear enhance visibility in low-light conditions.

This tee is not just a running shirt; it's the perfect foundation for your training kit, designed to complement the entire SiTech range. Featherweight and incredibly breathable, you'll feel just as comfortable on the last mile as you did on the first. Elevate your running experience with the TRI-FIT SiTech Women's Running 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.
