Choose this jacket for riding in cold but not freezing temperatures, or for high intensity riding, or if you sweat a lot. This jacket excels in a wide range of conditions, as long as it's not bitterly cold or raining.It's the combination of the right fabrics and construction that make it work so well. The biggest cold blast is on the upper chest and arms, so we use our three-layer GORE-TEX INFINIUM™ WINDSTOPPER® X-Fast fabric with a luxurious fleece inside for extra warmth. The lower part of the front is GORE-TEX INFINIUM™ WINDSTOPPER® fabric with a softly brushed interior. Both of these fabrics provide 100% wind protection, excellent splash protection and best-in-class breathability. The reverse side is our brushed 100% polyester fleece, but it is not windproof, so it lets a lot of moisture through to the outside. You'll stay dry and therefore warm and comfortable.The jacket has a neutral fit. It's not too tight, so there's room underneath for an extra layer, but you definitely won't be shivering in the wind.
