I have now been using a Peak Custom drysuit for about 6 months on rivers and for playboating and I have been very pleased with it. Not only is the drysuit really good quality but the ability to have your own customised design incorporated really well into it makes for a winning combination.
Made with X3 material rather than Peak's new X4, the suit is lighter than their current model which I prefer as I found their other suit a little heavy. It's really water tight though as still keeps me warm enough while I'm on the water.
The U-zip bottom entry also means that it is really easy to get into and doesn't require a friend to zip it up once you are inside. This feature also makes up for the lack of a relief zip on the front.
And then there is the custom designs! All that you have to do with this is send in any design that yo want to Peak and they will put it onto the drysuit! Of course there are extra costs involved in this with the price going up per hour of work that is required on the design. Therefore it is best to get the design as close as possible to the templates provided on the Peak website.
Once that is all sorted though the design is printed onto the fabric really well. The material itself is coloured as per the design meaning that it won't peel off or fade away anytime soon. Also after a good few months of use, its still white!
