Graded Sizing: Stohlquist's Graded Sizing offers the best fit, and lowest footprint possible, for the widest range of body types. Each individual size has been fine tuned, and sculpted. The foam footprint and foam thicknesses provide a better fit and more comfortable PFD for people of all sizes. This allows a better fit for younger, smaller framed paddlers up to larger adults in the same style vest, while offering the same amount of mobility and a low-profile fit across the entire size range.
