The dangerous tendency not to wear a PFD is most often a decision of comfort. These vests, which are USCG-approved Type-III PFDs, are cooler, more flexible and less restrictive than conventional vest designs. The wide-open arm holes allow unlimited freedom of movement, so they won't bind when you're facing a long day of fishing or other water-based activity. Chest sizes:S/M(36-42), L/XL(44-50), 2XL/3XL(50-56). Colors: Red, Forest, Taupe.
