The O'neill Women's Law USCGA Life Vest has an exclusive segmented-foam core that allows the vest to compress, twist and expand like a second skin. Anatomical flex points, minimal bulk design, and stratgeic armhole size ensure a great fitting U.S. Coast Guard Approved Life Vest. The Law also has wind resistant glideskin, a lightweight fluid-foam neoprene shell, integrated dual belt, overlock stiched super-strong seams, zipper safety tab, and mesh for drainage.
