The advantages of muscle compression are no secret. We know how our bodies feel after a few hours in compression wear compared to the dark ages of old wives' remedies. So when it comes to staying warm and keeping your muscles comfortable during fall and winter rides, slip on the 2XU Long Sleeve Thermal Compression Top under your jersey to help prevent early muscle fatigue and stay warm. Compression tops are made to hold close to the body like a second skin, but certain parts of the body need more compressing than others, which is why 2XU uses a graduated compression fit for the Thermal compression Top. A graduated fit puts compressive pressure throughout the base layer, focusing a higher amount of pressure at the extremities, gradually decreasing towards the heart. This style of fit increases circulation and reduces soreness, while also reducing vibrations. Since muscle support is why you are wearing the Thermal Top, the highly compressive fabric adds support throughout your chest and arms, pinpointing support to your forearms, triceps, biceps, pectorals, and deltoids. The raglan sleeves eliminating seams over your shoulders, so your movements aren't constricted while you ride or nordic ski. 2XU uses soft, brushed, PWR FLEX fabric throughout the baselayer for optimal warmth. Moisture wicking elements throughout the material keep your skin dry while the PWR fabric regulates your core body temperature. So you can end your ride smelling fresh, the fabric has an antimicrobial treatment to stave off bacterial growth that causes odors. The 2XU Long Sleeve Thermal Compression Top comes in Black and is available in four sizes, Small through X Large.
