The NRS Crew Universal PFD is ideal for flatwater boating and close-to-shore safety. No frills or fancy stuff; this life jacket just offers safety and all-day wearing comfort. This PFD is approved under the new certification system for PFDs. It's dual certified, carrying both a US Coast Guard Approval through Underwriters Laboratories (UL), and a Transport Canada Approval through Underwriters Laboratories Canada (ULC). Universal Plus sizing adjusts from 33"-58" chest measurement (including apparel layers) and is intended for users weighing over 90 pounds. Four side adjustments and a waist adjustment make for a comfortable fit. Tough 200 denier nylon shell stands up to years of use. Improved shape of the shoulders and arm openings have been changed for better fit and mobility.
