While the Skins top isn’t solely a base layer, but it does a great job of wicking sweat away from the skin, and also works to keep the body at a constant temperature. This means it’s great whatever the weather, keeping you comfortable when you’re exercising hard.
It's also a compression garment, designed to help ease muscle fatigue. It does this by compressing the muscles with a tight fit that's claimed to help reduce lactic acid build-up while increasing the low of oxygen and circulation.
Of all the compression clothing we have tested, Skins stands out, and we feel it works very well as a base layer, too.
