Why Your Short Sleeve Is Secretly Slowing You Down in the Sun The plot twist your race-day wardrobe has been waiting for...When the sun comes out, most of us do the same thing: strip down. Short sleeves, no sleeves, or shirt off entirely. The logic seems airtight: less fabric, less heat, more speed.Plot twist: in direct sun, the research says the opposite. A long-sleeve shirt made from truly high-performance fabric, with elite moisture-wicking and maximum breathability, doesn't slow you down. It protects your performance.Here's the science, and why it might change how you dress for training and race day. The 50% Problem In a landmark study in the European Journal of Applied Physiology, researchers put trained athletes on bikes at 70% VO₂max in a controlled 30°C/86°F room. Then they played with the sun: 800 W/m² (full sun), 500, 250, and 0 (shade). Temperature, humidity and effort stayed identical. Full sun...

SKILD PRO: Graphene Does the Cooling SKILD PRO is our shirt for taking your training and races to the next level. It uses graphene-integrated, thermo-regulating fabric first developed for the Tokyo 2020 Olympic Games. It lets heat move between the warmer and cooler parts of your body and the world around you. Graphene is the material behind the 2010 Nobel Prize in Physics, awarded to A. Geim and K. Novoselov.Graphene Grid Flow Technology. A seamless graphene pattern is printed on the inside of the shirt. Graphene is extremely conductive, so it spreads your body heat over a big area and takes the heat stress off you. It pulls heat away and dissipates it faster, so your body burns less energy just keeping its temperature in check.Your Fabric, Your Call. Got specific pain points? We can work with almost any fabric that fits what you need: Temperature regulation tuned for warm...

Built to Keep Your Cool: SKILD Temperature-Regulating Performance Wear SKILD shirts run on what we call our "breathing fibre" technology. It's a lightweight mesh fabric woven with bamboo charcoal, and it does three things really well: it lets air and moisture pass through, it soaks up sweat fast, and it feels soft on your skin.The bamboo charcoal also has a natural, long-lasting antibacterial effect, so your shirt doesn't turn into a science experiment after a few sessions.What's in the Shirt We packed all the important stuff of a high-performance fabric into one shirt: Made for endurance, outdoors and indoors. Made for normal to hot and humid conditions. Super lightweight mesh for airflow, moisture wicking and quick drying. Bamboo charcoal fibres for a super smooth feel on your skin and no funky odour. 4-way stretch so it moves with you and feels good all session. Non-compression fit, so more air flows...
