Material: TechnoButter 3X Style: full Water Temp: 52°-58°F Thickness: 4mm, 3mm Hood: none The HyperFreak F.U.Z.E. (Chest Zip) is constructed with super light TechnoButter 3 and TB3X neoprene. We added 0.5mm thicker material as a step-up from the HyperFreak Comp. The minimal seam design, lightweight, quality construction, and attention to detail make this another team inspired favorite.
