This is a THE NORTH FACE Alpine Light Pant in size XXL. (Please refer to the 5th image for sizing.) I purchased it in June of this year, and have worn it less than 10 times. The original purchase price was 15,890 yen. (The following is quoted from the website where it was purchased) The THE NORTH FACE Alpine Light Pant is a favorite among industry professionals for everyday wear. It's comfortable with its [extreme stretch] that you won't want to take off once you put it on. The [moderate thickness] is neither too thick nor too thin, resulting in a perfect finish. These pants support activities in mountainous areas throughout the year. The blended fabric, which uses polyurethane and recycled nylon, has high stretchability and features knit-like elasticity and comfort. Despite the tapered silhouette, the three-dimensional pattern allows for smooth leg movement. The waist has a clean design without a buckle, anticipating the use of a harness. The front zipper has a double slider. With its simple design, it's a versatile piece for everything from climbing to hiking.
