I have only worn this once so far. I love the colour and look of the product. The double layering is effective on the chest area but the arms require a second layer underneath as the material is quite cold against bare skin, which feels unusual. Climbing a hill is quite warm, but the descent was cool minus arms underneath.
Sizing is not quite right. I went for a medium, as per my other winter cyclogy jersey. It is a lot roomier across the chest but tight on arms, which are quite stiff. The high neck is fantastic.
I really need to wear it a few more times and perhaps wash it to soften it up?
