I am selling some mountaineering gear as I reorganize my equipment. I purchased these about two years ago and wore them about seven times. There is a general feeling of use and some damage. I'm unsure about the waterproofness, but they kept snow out, and I didn't feel any particular inconvenience when using them in snowy conditions. I understand that the overall condition is poor, so please check the photos carefully before purchasing. Thank you for your consideration. The following is quoted from the Montbell official website: Product Information These pants combine strength and lightness, suitable for winter mountain traverses exceeding 3,000m in altitude, and for professional use by mountain guides. They feature GORE-TEX Pro, which offers amazing breathability and durability. The sleek silhouette doesn't flap, making movement easy, and they are also useful for ice climbing and snowshoeing.
