MAVIC COLD RIDE MEN LS TEE Base Layer Men's XS/S Mavic Cold Ride LS Base Layer This is a base layer (underwear) for autumn and winter, suitable for temperatures between 0-15°C! It's a mid-weight long-sleeved base layer with excellent moisture management and insulation. It has both insulation and quick-drying properties, and is comfortable to wear thanks to its seamless construction! It keeps your body temperature at 37.5°C, the ideal temperature during exercise, allowing for comfortable temperature regulation and dryness even on cold rides. Mesh material is placed on the back of the neck and both sides to prevent discomfort. It's designed to fit the cycling posture, with a slightly longer back to prevent the back and abdomen from getting cold, and set-in sleeves that don't restrict arm movement, allowing for natural movement even during intense dancing. There's a difference compared to Uniqlo's Heattech when you sweat. Heattech is for everyday wear and isn't designed for heavy sweating. The way your body cools down after sweating is different. That's the difference between it and cycling underwear! It's an essential item for comfortable autumn and winter rides. ■Size: XS-S (equivalent to Japanese size) ■Color: White Type...Base Layer Gender...Men Sleeve...Long Sleeve
