Introducing the TRI-FIT SiTech Dual Running Shorts – your ultimate companion for all activities, whether it's a long run session where comfort is crucial or a gym workout where extra support is needed.

Designed for versatility, these shorts received a stellar 90% rating from 220 Triathlon, hailed as "near-perfect run shorts." The double-layer construction incorporates highly technical fabrics and manufacturing techniques, ensuring optimal performance in every move.

The exterior boasts a loose-fitting and super lightweight shell fabric with reinforced thermo-welded seams, providing durability for all your activities. Inside, a mildly-compressive woven fabric with flat-lock stitching offers a close, comfortable fit and added support for your quads – perfect for enduring running sessions.

Featuring a technical and unique breathable mesh waistband with an integrated elasticated drawstring for maximum comfort and fit, the flat-lock seams inside eliminate chafing even during your longest runs. Reflective strips on each thigh illuminate your outline in low light, while two essential pockets provide storage for emergency gels, phone, bank card, or money.

Carefully chosen fabrics with 20% elastane offer just the right amount of stretch, aiding moisture-wicking and breathability for comfort during vigorous activities. The TRI-FIT SiTech Dual Running Shorts are a versatile and essential addition to your year-round athletic wear wardrobe, ensuring you stay comfortable and supported in every run.


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.
