Introducing the TRI-FIT SiTech Women's Athletic Bra – a versatile standout that excels in running, cycling, triathlon, yoga, and athletic training. Awarded Best In Test 2022 for Women's Running, this bra is designed not just to go under your athletic wear but also to stand alone as the perfect training top.

Premium soft-touch fabrics, chosen for durability and performance, make this bra ideal for the demands of running, cycling, racing, and more. The raw-cut, wider straps with reinforced, taped seams and a double layer of chest fabric provide maximum support during the toughest training sessions or races.

Experience complete freedom of movement with the Y back design and 20% elastane, offering an elasticated feel without compromising on support or comfort. Thermo-welded seams across the chest reduce skin friction, while laser-cut ventilation adds to the bra's aesthetics and technical specifications.

Front and rear visibility are ensured with subtle reflective elements, and for women seeking extra support, there's an option to insert bra cups. Two years of design, development, and testing have resulted in the perfect all-around Athletic Bra, suitable for all sports. Elevate your performance with the TRI-FIT SiTech Women's Athletic Bra.


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.

    Supportive, soft and stylish

    Really high quality, supportive, and buttery soft sports bra that is just as effective for both low and high impact sports. No rubbing, chafing or discomfort. Highly recommend.
