Find Clothing from Loeffler for running and triathlon

Discover Loeffler, the pinnacle of Austrian engineering in high-performance apparel, meticulously designed for the dedicated runner and triathlete. For decades, Loeffler has been synonymous with innovation, quality, and an unwavering commitment to helping athletes achieve their peak potential. At the very core of this performance ecosystem lies the most critical piece of your gear: the base layer. Loeffler has perfected this essential first layer, transforming it from a simple undergarment into a sophisticated climate-control system for your body.

The foundation of your comfort and performance on any run or during any leg of a triathlon starts with what’s next to your skin. Loeffler’s collection of running and triathlon base layers is engineered to provide an unparalleled second-skin feel, managing moisture and temperature with scientific precision. The secret to this superior performance is Loeffler’s groundbreaking and exclusive Transtex® technology. This unique, two-layer knit system is a masterclass in moisture management. The inner layer, crafted from polypropylene, works tirelessly to pull sweat away from your skin, ensuring you never feel clammy or chilled. This moisture is then rapidly transferred to the outer layer, a functional blend of natural and synthetic fibers, where it spreads out and evaporates with incredible speed. The result is a perfectly dry and comfortable microclimate, allowing you to focus completely on your pace, form, and effort.

Whether you´re facing a frosty morning run, a grueling marathon, or the intense transitions of a triathlon, there is a Loeffler base layer built for the challenge. The Transtex® Light series is your go-to for high-intensity workouts in mild to warm conditions, offering maximum breathability and a barely-there feel in sleeveless, short-sleeve, and long-sleeve options. When the temperature plummets, the Transtex® Warm collection becomes your essential thermal shield. This line provides exceptional insulation without adding bulk, trapping body heat while continuing to expertly wick away moisture, preventing the dangerous chill that can set in from sweat. For the hottest race days, Transtex® Superlite offers featherlight construction and active cooling properties.

Every Loeffler base layer is designed with an ergonomic, athletic fit that moves with your body, offering complete freedom of movement without restriction. Advanced seamless construction and flatlock seams eliminate chafing and pressure points, a crucial detail for long-distance runners and triathletes. This meticulous attention to detail ensures that your first layer works in perfect harmony with your body and your outer layers, from running tights and shorts to windproof jackets and trisuits.

Choosing Loeffler is an investment in your performance, comfort, and endurance. Experience the tangible difference that superior materials, innovative technology, and meticulous Austrian craftsmanship can make to your training and racing.
