Let me ad a little more about the Triumph one piecer i have.
It is very easy to get on/off, even on the side of the road. After a few times it becomes second nature.
It is 100% waterproof. I rode to Georgia last year for 3 days straight in pouring rain and stayed dry and warm. To take a leak you have to take the whole thing off though. That is a minor pita. It's all or nothing with this suit.
