Yes, they are more of an 'American' fit than an 'Italian' . If you do decide on Klim and you're going to use it in winter months you will need a down jacket or something underneath. I use my Rukka in winter as it is warmer.
I’ve had three Klim jackets @Pedro
Ive still got my Overland and I have a Carlsbad as well now as well as overland and Dakar trousers.
In my experience the fit is on the big size especially compared to Dainese.
Our sizes are done in S M L XL etc but I can measure my jacket if you like
