✔ TechnoButter 3X (arms/shoulders)
Featherlight and super stretchy, this premium neoprene enhances freedom of movement while staying soft and durable.

✔ TechnoButter 3 (legs/lower body)
20% lighter and 30% less water absorbent than traditional neoprene – keeps you warmer and drier, longer.

✔ Firewall Smoothskin
Thermal wind-blocking barrier to retain heat in critical areas.

✔ Fluid Seam Weld construction
Non-irritating urethane seals over GBS seams provide maximum waterproofing with unrestricted flex.

✔ F.U.Z.E. Chest Zip + built-in hood
