Also, I don't mean to say that this item is the most cost-effective, but I actually own five pieces made from this material, which come in different colors and lengths. For this particular item, I remove the liner and wear it until about mid-April, after the cherry blossoms have finished blooming in spring. From around the chilly days of October, like today, until the end of April, I can keep removing and reattaching the liner, which means I can wear this item for about two-thirds of the year. That's one of the features of this item.
Additionally, this is made of polyester and nylon, but it moves just like natural fibers, so in that sense, I can wear it for a relatively long period by removing the liner. Of course, since the density is high, it keeps the wind out and is warm, and it breathes properly when it gets humid, making it a great product.
