    Introducing the TRI-FIT SiTech Singlet – your ideal companion for staying cool and free in warmer weather, whether you're running or training.

    Crafted from lightweight and stretchy fabric, this singlet offers maximum breathability with minimal weight, making it perfect for purposeful training or running in the heat. The tailored fit with wider shoulders ensures comfort during high-motion activities, and innovative construction moves all seams away from areas prone to rubbing.

    The rounded neckline enhances on-body comfort specifically for running, and laser-cut ventilation promotes heat release. Thermo-bonded seams and hems keep weight down, while reflective elements at the front, side, and rear ensure visibility during low-light conditions.

    The TRI-FIT SiTech Singlet is designed to be your go-to lightweight training top for all your warm weather running sessions. Stay cool, comfortable, and visible with this versatile singlet.

    About TRI-FIT

    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.

      Great socks for HIM + Long Rides

      Wore these during some long rides and for a HIM. Good compression and breathable enough for the run. No need to change socks in T2 - these held up great! Silicon takes a sec to get used to but doesn't cause any issues. I do think it helps keep grip for the run. Hell, I even use them as my house socks.
