I really like Endura as a brand: their products are well made, last a long time, and are designed to accomplish their purpose. This jersey is no different.  It works well for me riding in Western Canada’s cool-ish fall season.  At 7° Celsius and with a mild wind, this jersey, in combination with a long sleeve base layer, kept me quite warm.  The front and sleeves have a kind of “rubberized” material that cuts the wind.  The inside has a very thin but effective fleece in the front.  Size-wise: I am 5’11” and weigh 180 lbs. Athletic build with somewhat long arms. The large size in this jersey leaves room for the aforementioned base layer, but still is not too tight. Fits perfectly.  I think this jersey carries on the Endura tradition of providing quality, durability, and function.
