For this winter, I decided to give the O'neill Mutant (4/3) a try. In previous years, I have owned Xcels, an O'neill Psycho 2, numerous Rip Curls, and a Matuse.
I loved Xcels fit and warmth initially, but was unhappy with their durability, as I would only be able to get 1 or 1 1/2 seasons with them before they started falling apart. I was really hesitant to spend $420 for a drylock that might only last one season.
I found the Psycho 2 to be a little stiff, as the double fluid seam weld felt a little too restrictive. I would find myself getting tired a lot faster. The material also felt like it got stiff over time and the suit lost its warmth rather quickly.
I used to buy Rip Curls all the time. I loved them when they first came out with the draw string suit quite a few years ago, but I felt like their quality went downhill really quickly since then. I gave last years F-Bomb a shot, and it was by far the worst suit I've ever owned.
I thought the Matuse would be this years winter suit (4/3/2), but I quickly found out that it wasn't going to be warm enough to get me through winter. This suit feels really nice, it's flexible, and light, but just doesn't quite have the warmth that my Xcel 4/3's had. It's a great 3/2, but not a 4/3 for me.
As for the Mutant, I've only owned it for a month now, but I really like it. It's very warm, much more flexible than the Psycho 2 that I owned previously, and does not show signs of wear yet (my Xcels chest zips would have ripped along the neck entry area by now). It's also really nice to be able to unzip the standard neck on the Mutant and zip a hood on it. The only downside to the suit that I have noticed is that It can take a little more than a day to dry at times, where my Matuse will dry overnight.
