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 favourite. Features: F.U.Z.E.
