While not Gore-Tex, it has waterproof and breathable properties, so I think it will be comfortable in rain or snow. How about it for mountain climbing, sports, work, commuting to work or school, or snow removal in the rain or snow? Features: This raincoat uses a supple and lightweight original waterproof and breathable material, achieving excellent breathability and lightweight compactness. It features a simple hooded design and can be used not only as a raincoat but also as a coat in the chilly season. The condition of the product is considered to be without any noticeable scratches or stains. Please note that it will be shipped as compactly as possible. I have various other items for sale. I also have items from Uniqlo, Muji, The North Face, Patagonia, Montbell, Workman, and more.
