The last couple of months i've been testing this Nineplus stylist wetsuit and so far i'm very impressed. The latest generation of suits seem a real step up in quality from the last nineplus suit i had a couple of years ago. Mostly single lined 3mm Yamamoto neoprene, it's soft, fits like a glove and is supple and flexible too. Seams are glued blindstitched and spot taped on stress points. The "shorts" area in particular feels very flexible, you aren't aware of the seams in this area at all.
Closure is with a back zip and a generously sized "batwing" collar underneath to keep it watertight. It's a warm suit and i'm looking forward to getting my full leg version soon which i'm sure will be even warmer!
The big problem with the Nineplus suits i've owned in the past has been durability but so far it doesn't look like an issue thats going to affect this suit. All in all, stylish, warm, flexible and good value for money.
