APF means All Person Fit – one jacket that does it all! Mothers, daughters, sisters, girl friends - this is one vest that you can share and everyone looks good! The universal sizing easily adjusts from a 30 in. to 56 in. chest - petite to plus size in a cinch. The slim front panel foam isn't bulky and over time contours to the shape of a women's bust. Adjustable neoprene shoulders, open sides, reflective tape, and hideaway strap pockets. Three simple front buckles. Great colors for a great time on the water!
