OXYVAN Chest Fishing Waders for Kids, Waterproof Lightweight Youth Waders with Boots, Nylon/PVC with Boot Hanger for Fishing & Hunting. I bought these not knowing much about sizing and they are too small for anyone in our family. I think they are good for tall and thin, we are all short and fluffy. The tag says 10/11. I also found a pic of the sizing chart. They are really nice and brand new. NEVER WORN
