New with tags. Size 10 The HyperFreak F.U.Z.E. (Chest Zip) is constructed with our exclusive super light Recycled TechnoButter 3 and TB3x neoprene containing 90% or more recycled fibers in the liner fabrics. We added 0.5mm thicker material as a step-up in warmth from the HyperFreak Comp. The minimal seam design, lightweight, quality construction, and attention to detail make this another team inspired favorite.
