A thermal undershirt is a great way to continue using your favorite cycling jacket even on colder days. Undershirts help the body get rid of excess fluid / sweat, they are directed to the surface of the material, where it spreads over a larger area and dries faster. Undershirts are the first layer of clothing closer to the body, so its choice is very important. They will also provide extra comfort, as you will feel less seams from other clothes, shirts, shorts. It is important to choose the right size of the undershirt, it can not be too small,  it will be too tight, but can not be too large either, then wrinkles may form and it will not fit snugly and will not be so effective in relieving sweat from the body. The knowledgeable sellers in our store will definitely help you choose the right type and size of underwear for your planned activities!
