Great jacket apart from ONE thing

Nice fabric, good fit, stylish

The front zips up all the way to your nose

This jacket was exactly what I was looking for, unfortunately there is a very invasive feature that ensured I had to take it back. The front zips up extremely high, leaving only your eyes/nose showing, obviously to give you great protection during a windstorm. The unfortunate thing is for 90% of use (when you aren't standing in a hurricane) you have these enormous lapel flaps that just get in the way and look terrible. I mean If you work in a wind-tunnel then this jacket is for you.

used for 2 to 8 weeks Great softshell. Not been a fan of this type of outdoor wear. Refused to pay over inflated prices charged by popular brands. These are equally as good and at the price I gave it a go. Not disappointed. Water resistant to a high degree. Windproof and has the benefit of a hood. Love it so much bought another. Can't fault it. Quality at a good price. Used in anger on several occasions on the Mountains of North Wales.

I am from the US, I bought this Jacket while working in France. This is hands down the best jacket I have owned. It has stood up to the rough life of a roadie on tour and years later it is still my Go to jacket as soon as the weather is right. It is also the only jacket I wear as a base layer while riding my motorcycle. Best value for the money I have ever found.
