Find Clothing from Precision for running and triathlon

Discover the pinnacle of athletic engineering with PRECISION, the brand dedicated to empowering runners and triathletes to push their limits and achieve new personal bests. At Runnerinn, we understand that success is built from the ground up, which is why we are proud to feature the exceptional range of PRECISION base layers—the fundamental core of any high-performance apparel system.

At the heart of the PRECISION collection lies a meticulously engineered range of base layers, the critical first step in your performance layering system. These are not just undershirts; they are your second skin, designed with a singular focus on optimising your body´s microclimate so you can concentrate solely on your performance. Whether you´re tackling a frosty morning run, a sun-drenched marathon, or the gruelling multi-stage demands of a triathlon, a PRECISION base layer is your first line of defence and your greatest comfort.

Experience intelligent thermoregulation that adapts to your effort and the environment. During intense winter runs, a PRECISION long-sleeve base layer traps a thin layer of warm air to insulate you from the cold, while its superior breathability prevents overheating and the subsequent chill from built-up sweat. In warmer conditions, our lightweight, short-sleeve, and sleeveless options work to enhance evaporative cooling, featuring advanced moisture-wicking technology that rapidly pulls perspiration away from your skin. This ensures you remain dry, light, and comfortable, preventing that cold, clammy feeling that can drain your energy and focus.

Every seam, panel, and fibre is chosen with purpose. The result is an ergonomic fit that moves with your body, not against it. Utilising four-way stretch fabrics, PRECISION base layers offer complete freedom of movement, whether you´re powering up a hill, maintaining your aero position on the bike, or transitioning to the run. The seamless or flatlock-seam construction minimises friction points, delivering a chafe-free experience that is absolutely essential for marathon training and long-course triathlons. Forget about distracting discomfort and focus on your rhythm and pace.

The PRECISION philosophy extends beyond a single garment. These base layers are designed to integrate flawlessly with mid-layers and outer shells, creating a cohesive system that protects you from the elements without adding unnecessary bulk. For dedicated runners and triathletes, this versatility is key. Wear a PRECISION base layer on its own during a temperate training session or as the foundational piece for your cold-weather running kit. Equip yourself with the technical advantage of PRECISION apparel and build the ultimate foundation for every run, every race, and every victory. Explore the collection at Runnerinn and feel the difference that true precision makes
