What Our Gearhead® Experts Are Saying: "On intense training days, the S/Lab Speed Tee is the one I trust. It’s insanely light, dries faster than anything else I own, and the 3D knit keeps air moving when the heat ramps up. It feels almost weightless, but still holds up through long, sweaty efforts. Perfect for runners who want true performance without distractions." We pull on the Salomon S/Lab Speed T-Shirt when our training demands maximum speed with minimum weight. Designed with input from top athletes, the S/Lab line is all about pushing limits, and this tee reflects that purpose from the first stride. Its featherlight profile and next-to-skin comfort let us settle into a fast rhythm without feeling held back. Knit_Flow technology elevates breathability with a 3D structure that moves air continuously, keeping thermoregulation dialed even in punishing heat or long intervals. Moisture is whisked away as quickly as it forms, letting us push harder, recover faster, and stay in that performance sweet spot longer.
