Hi John, a friend has a pair, has had them for ages and abuses them.
Comes off the river, chucks them in the boot and leaves them there till the following week.

He hasn't had one problem with them.
They look well made to me, I have had the Bison boots and they were also good for the price.
I would think a medium will do for you, your collar size isn't really an issue here.
