Not just Gil most of the coastal stuff leaks after a year.
We use these for when it's cold and wet really impressed. Still like new 18 months on. Bit of work to get on and off but very waterproof and warm. Have to be careful not to sweat in them though.
I've seen those and have been eyeing them up. Price is better than just a jacket for the top name brands, and the drysuit aspect has to be a bonus when its wet and shitty out.
