Size up if you have broad shoulders
Negative: Size up if you have broad shoulders - because the length is short and fitted. Absolutely keep the Technobutter away from Velcro. Belly Button Zipper system is weak and will easily tear smooth skin if not careful
Positives: Ultra flexible
Very easy slide you arms in.
Very warm and easy to paddle with esecially if its windy.
Technobutter 3 is like a very good interior lining without the Neoprene sandwich on top.
For the price and performance you get its unbeatable.
Took some heavy wipeouts and the jacket did not get flusheshed or did the zippees pop open like my 3x expensive Matuse Jacket
