I've used these a few times for mountain climbing, but haven't had the chance to use them much lately, so I've been storing them. Please check the photos for the condition, but there are no noticeable stains or marks. They're stretchy, so they allow for good leg movement when climbing, and they're quick-drying, so they can also be used for everyday wear. As for the size, they fit me perfectly at 168cm and 62kg. Please understand that these are used items before purchasing.
