The key feature of 37.5 insulation is its ability to make you comfortable, which ultimately helps you perform better. When you are cold, it warms you, when warm it cools you.

37.5 technology removes moisture before it turns into sweat, helping you maintain an ideal core temperature so that you can perform your best. Climate control clothing with 37.5 Technology has been proven to decrease the rate of core temperature buildup, increasing athletic performance by up to 26%. Whether you’re training, competing, or recovering, your performance depends on staying in your comfort zone as long as possible.
