I purchased a long john and a top from the official Patagonia online store at the same time. Size: S Height: 160 cm. Weight: 60 kg, slender build. I was able to use them without any problems. For detailed information on the size and materials, please check the Patagonia online store. I used them for two seasons, but I have another set, so I mainly used that one. Therefore, these are used items, but they are still in good condition. The top is in very good condition. I hardly used it. The top is also size S. These are sold as a set.
