The Will 1.5 front zip top combines modern performance with retro styling. This long-sleeve top is made with the latest Eicoprene technology, a non-petroleum based synthetic foam derived from a mix of oyster shell powder, limestone, and recycled tires. To laminate the recycled polyester lining we use Aqua-A™, a solvent-free water-based glue with no harmful chemicals. The Will top is designed for spring and summer sessions. The Glideskin neckline means staying warmer longer, and its B-stitched chafe-free technology provides extraordinary comfort when riding big waves. It also features a boardshort attachment cord and fuse-cut finish to minimize water entry. We combined performance with a refined, tailored fit.
