what size life jacket do i need

To determine the size of a life jacket you need, it is important to consider the manufacturers size and weight ratings. Life jackets are typically sized based on weight range, and the size chart is based on chest size. It is recommended that a life jacket should fit snugly and feel comfortable, allowing for free movement without chafing. To test the fit of a new life jacket, you should check the manufacturers ratings for your size and weight, make sure the life jacket is properly zipped and/or buckled, and raise your arms above your head while wearing the life jacket to check for fit. If it slides up, the jacket is too large. It is also important to practice moving around with the vest on to ensure that you have the right range of motion necessary for your specific water activity.
