XSPAN 2.5MM SPORTS VEST
Product Description Now available in our exclusive XSPAN material!
Smart layering can significantly improve warmth while diving, and this front-zip vest wears easily under or over a full suit or skin. The sleeveless cut leaves arms free for complete mobility and makes the Sport Vest a natural cross over garment for paddle sports, skiing and watercraft use. Light and easy to pack, the Sport Vest is also durable, thanks to quality neoprene and flatlock seam construction.
