This is a PROX chest-high wader. It's a size LL, designed for people with feet in the 27-27.5 cm range. I usually wear shoes between 26.5-27 cm, and it fit perfectly. The body has adjustable belts, so it shouldn't be too big or too small. I bought it for firefly squid scooping in Toyama. I've used it about 5 times. I'm selling this one because I bought a new one. I checked for leaks by submerging it in a river up to my knees for about 10 minutes, and there were no leaks. There is one spot where the fabric is peeling, as shown in the photo. It didn't leak during use, so it doesn't seem to be a problem, but you could reinforce it with glue if you're concerned. This is based on my amateur assessment, so please refrain from purchasing if you have any concerns. Thank you for your consideration.
