PFDs for children run the gamut from simple models to extravagant ones. The most important factor is to make sure you pick one for your kids that has been approved by the U.S. Coast Guard. If it is not Coast Guard-approved, it’s not going to provide your children the level of protection you want them to have. Sizing for youth is weight dependent, not age. Infant PFDs are made for children from eight to 30 pounds, child PFDs for children from 30 to 50 pounds, and youth PFDs from those 50 to 90 pounds. Like adult PFDs, kids’ life preservers should fit snugly. Consequently, plenty of adjustment is not only needed for a perfect fit but is also handy to ensure the PFD can grow with your child until he or she needs to move up to a larger size.
