These quilted pants, which are sold out online, are filled with warm insulation. They are incredibly warm, and I've been wearing them all winter. They are water-repellent and washable, making them easy to use. The snow guards at the cuffs are also very useful in snowy regions. They are a very good product. The color is versatile and beautiful. How about them for saving on heating costs, for disaster preparedness, or for sports? Thank you. ----------- Montbell, Millet, Drynamic Mesh The North Face, Karrimor, Mizuno, Alps Arc'teryx, Salomon, Haglofs Outdoor, Ski, Wear, Snowboard, Layering Trail running, Trekking, Mountaineering, Camping Size: M
