Review on Kid'S Shorty Wetsuit - Hyperflex Access 2Mm Back-Zip Springsuit With 4-Way Stretch Neoprene, Adjustable Collar, And Flat Lock Construction - Provides Warmth And 50+ UV Protection by John Reese

I bought this for my son (just turned 8, 49”, 48 lbs) in a size 6. It is large, but he can still wear it. The photo is a size 6 hyperflex laying on top of an O’Neill size 10 (the shoulders are matched up). The O’Neill fit is good for a skinny kid. The Hyperflex is the same width in some spots, including the thighs and may be a better choice for a thicker kid. The Hyperflex material feels thinner than the 2mm O’Neill. For my thin child, I’d rather spend the same amount on a used size 6 O’Neill wetsuit for a better fit.
