Had 1 and my old Man has 2. As Crawford says they are thick, bit like a drysuit for diving. On the plus side they are toasty warm and ideal for cutting out the worst wind.
I didn't find the thickness restrictive at all when swinging. Being bonded the water slid off like a well polished car. Only bad thing I would say is I got too hot and ended up slinging it in the bag.
Great functional jacket but not the nicest if your fashion concious.
