Designed to keep you dry in cool weather, the Prosecco Tech Long Sleeve Base Layer features a body mapping construction that allows it to provide exceptional wicking and the perfect level of insulation, right where it's needed.

The main body is made from a rib knit fabric with Prosecco hydrophilic treatment. While the ribbing traps air against your skin, helping to regulate your temperature, the treatment fends off water both inside and outside the base layer, ensuring you'll always feel dry and comfortable, even when you're working hard.

As well, thinner PrimaLoft® panels are used over your waist and back, since these are the areas you're most likely to layer your outfit. This ensures the insulation across your upper body remains consistant, so that you won't overheat when you're all layered up in cool weather.

• Prosecco hydrophilic treatment for maximum wicking
