This bundle pairs two running essentials where lightweight warmth meets locked-in stability. The base layer fits like a second skin: warm, featherlight, and completely chafe-free. The shorts stay anchored without squeezing, powering a fluid stride from start to finish. Base Layer • Chafe-Free Seamless Knit: Engineered seamless construction for lasting, irritation-free comfort. • Warmth Without the Weight: Spun from a finer, more supple yarn that delivers the same thermal warmth with less bulk. • Second-Skin Fit: Optimized thermal insulation with complete, unrestricted range of motion. • Targeted Cold Protection: Double-layered mock neck and raglan sleeves shield against biting wind and chill. • Cold-Weather Utility: Integrated watch window lets you track your splits without letting freezing air in. Shorts • On-the-Run Stability: Firm, supportive waistband engineered to stay locked in place without slipping or rolling. • Supportive, Never Restrictive: Contouring hold that hugs your body without pinching or squeezing. • Essentials Within Reach: Low-profile drop-in side pocket keeps your phone and keys secure and bounce-free. Now €135 (down from €168): gear up with the ultimate combination of comfort and race-ready performance.
