I am selling the previous model of Patagonia's top-of-the-line waders, the Expedition Zip Front. (Size: SSS) Purchased new in May 2021. I have used them for stream and lake fishing. I work at an outdoor shop and a fishing tackle store, so I believe I have handled the use and care of waders almost perfectly. However, after using them for over four years, there is some damage, which I will detail below: * In the first half of 2025, there was a hole and leakage in the right shin area. I requested repair from Patagonia, and they treated it with a heat press method. → During a lake fishing trip in December 2025, my clothes were slightly damp. It wasn't a major leak, but I felt it was becoming a bit questionable. I did a self-repair with Aquaseal UV from the inside, but I haven't tested it. * In the winter of 2024, a hole opened in the right knee area, causing leakage. I performed a self-repair with Aquaseal UV from the inside. Currently, there is no leakage. * Although there was no leakage, the fabric on the hip area had become thin, so I did a self-repair with Aquaseal UV. * The YKK zipper shows a slight sign of deterioration. After fishing involving deep wading, the outerwear I was wearing inside was slightly damp. * No leakage from other areas. * There are fabric tears on the back and gravel guards. However, there is no leakage or impact on use. * The most concerning part, the booties, have not leaked at all for four years. Perhaps it's a good pair, or maybe it's because of how I used them... The size is SSS. Please refer to the manufacturer's website for detailed dimensions. My usual sneaker size is 26 cm. I am 163 cm tall and have a slightly stocky build. I go to the lake even in mid-winter, but there is plenty of room even with proper layering. I will include the box, zipper lubricant, and a fly patch as a bonus. I am open to price negotiations, but I will ignore excessive price reductions. If you have any other questions, please feel free to comment. Thank you very much.
