The Prolimit Hydrogen Polar Boot is the warmest boot in the range, built for extreme winter sessions. With 6.5 mm neoprene and Zodiac plush lining, it delivers maximum thermal insulation. Fluid-taped seams and a dry-seal ankle cuff prevent water entry, while the X-Grip natural rubber sole gives barefoot-like traction. Reinforced heels and adjustable ankle straps provide a secure, comfortable fit.

Ultra-warm, protective, and performance-ready – the ultimate boot for cold-water explorers.
