REAL Review


The HyperFreak F.U.Z.E. (Chest Zip) is constructed with super light TechnoButter 3 and TechnoButter 3X neoprene. We added 0.5mm thicker material as a set-up from the Hyperfreak Comp. The minimal seam design, lightweight, quality construction, and attention to detail make this another team inspired favorite.

This wetsuit is amazing. Super warm in cold water (below 60) it’s thick but still very flexible. I was impressed by the fit and flexibility. Had also held up quite well. Heading into my 2nd winter season with the same suit.

Jason Forrest
The BEST winter suit.

I do lots of reviews on here and this is truly the ONLY product I've given 5 stars. I tend to give 4 stars 'cause I think there is always room for improvement on most products but this suit gets 5 stars.

I'm VERY opinionated on winter suits and while most brands have a good winter 5/4 you'll notice in the lineup on big, cold days that the experienced surfers, that buy their own suits are wearing very few models and brands. For us, here on the Outer Banks where it's cold AND windy on the good days, it's only O'Neill psycho techs and Xcel drylocks. There is a reason why there are the premier suits offered by REAL.

This suit is the ultimate winter suit in both performance, longevity and flexibility. It's warm, light and flexible and if you take care of it can certainly get two, MAYBE three seasons out of this suit.

My full suit quiver consist of a very light and flexible 3/2 from another brand. 3/2's can leak, tear and can be worn for years with blown seams. My 4/3 is a hyperfreak. This suit is ideal 'cause it's warm and flexible but doesn't last more that one or two seasons and the most... The hyperfreak is too flexible for big cold days. It's too flexible and flushes through the wrist, ankle or even neck on big wipeouts. The Pscyhotech is flexible but the cuffs stay in place and the neck doesn't flush.

It's winter. It's cold and it's pumping. Don't mess around with inferior suits. This is THE winter suit.
