Ok the code zero is the drysuit I personally use, the breathable fabric is so good that I can wear it all year and just alter my layering underneath to the temperature outside. I primarily use it for dinghy sailing , however I use it for kayaking as well as a neoprene deck fits snugly around the waist as the zip is not in the way. I love neoprene seals for comfort, I can do the zip up on my own and if I get caught short I have a pee zip . I will say it is a tailored suit, designed for fit olympic sailors, this is not me ,so where I would normally take a medium in Gul Dartmouth , I wear a large or a medium broad in the code zero. after all a drysuit should be a loose garment to allow for layers. The manufacturers blurb is as follows- The Code Zero Stretch U-Zip Drysuit, combines durability and comfort along with the essentials; being waterproof and windproof designed using GCX4 EVO WITH 2/2 mechanical stretch. Its contoured body panels reduce snagging, bulk and reduce windage. The glide skin neck and seal cuffs make it quick and easy to pop your head and hands in to while staying comfortable and sealed. Featuring a tough YKK Aquaseal Horseshoe easy on zip system, for ease of donning.
