Snow Peak pants made with TEIJIN Octa material. These bottoms are lightweight and provide excellent insulation. Perfect for everyday wear, as well as camping and hiking. I used them a few times a season for casual wear, but they became too tight and I haven't worn them since, storing them in my dresser. The size is M in Japanese sizing, but they would likely fit someone who usually wears a Japanese S size, or a woman who prefers a looser fit.
