Yamamoto Betty Jane

The Betty Jane is a modern women’s wetsuit, crafted for style, performance, and freedom in the water. Made from premium Japanese eco limestone-based material, it offers buttery softness, lightweight warmth, and exceptional stretch. Ideal for water temperatures ranging from 65–75°F (18–23°C). The sleeveless, full-length silhouette is built for balance: long legs provide sun protection and core insulation, while open shoulders allow full range of motion and breathability in warm conditions. Each seam is hand glued and blind-stitched for strength, warmth, and a watertight seal. Unlike flatlock seams that let water through, this construction stays sealed and lasts longer—reinforced with bonded nylon thread for durability in salt, sun, and surf. Marked with the ‘J’, subtle and iconic.
