• Thicker Polar Fleece: By replacing the Micropolar from the classic BZ400 with a higher performance fleece Thermo Pile 100 for increased warmth and comfort, this new BZ420X features more resilience to excessive wear, increased range of motion and freedom of movement and a thermoactive fabric that is breathable.
• Reinforced Design: A contrast in the materials, Santi has added reinforcements on the upper chest and shoulders ensure durability in areas prone to wear, without sacrificing flexibility. The men’s version also features side pockets.
• Modernized Aesthetics: Santi is known for making not just some of the most functional equipment, but also the most aesthetically pleasing, so their undresuit design has been refreshed, swapping the diamond quilting for a more modern “brick” pattern, offering a sleek, updated look that complements its superior performance.
