This is a set of Teton Bros TB jacket & pants. The jacket is made of the new Täsmä material, and the pants are the previous Polartec version. I'm selling them because I haven't been able to ski much due to family business. Regarding the pants, the hem has been simply repaired, and a part of it has been repaired with a Patagonia repair seal. Here's an excerpt from the product description: This is a flagship model specialized for backcountry skiing. Since its debut, it has been a flagship model that has matured through annual detail updates without changing its basic concept for 14 seasons. The waterproof and breathable material "Täsmä," which uses high-strength nylon for the base fabric, combines complete waterproofness and breathability, and has sufficient stretch despite being a nylon material. The angled ventilation that opens diagonally from the chest to the abdomen is easy to open and close, allowing for effective ventilation during activity. In addition, the convenient inner mesh pocket has been upsized, making it easier to take things in and out while wearing gloves. The unique cutting that ensures a wide range of motion allows for stress-free climbing and skiing.
