How to Fit a Hip Pack PFD
A hip pack PFD carrying an inflatable buoyancy aid should sit snugly around the waist. It must be easily accessible in case of emergency. It shouldn't be worn loosely, underneath a jacket or slung over a shoulder
How to Fit a Vest PFD
Traditional PFDs are fitted like a vest. Most will be zipped up at the front, whereas others go on over the head. However, all variations must have adjustable waist and shoulder straps to secure the PFD. Because there is nothing to deploy, they offer excellent protection. This comes with the compromise of being more restrictive than an inflatable hip pack style system.
Children's PFDs will also typically come with a strap that goes between the legs to stop the buoyancy aid riding up. It's important that this is done up and adjusted correctly as it prevents the life jacket from slipping off.
PFD Sizing
Most often, if you wear a size medium in a jacket, a medium size PFD would be correct. However, it is important to consider that PFD sizing also needs to take into account the weight of the user and any equipment they may be wearing. Before you make a purchase, ensure you check the appropriate size guide and select the size that fits both your weight and height bracket.
It is essential to ensure that PFDs are correctly sized with a secure yet comfortable fit around the torso. If your PFD is incorrectly fitted then there is a chance it may slip off in the water.
