I purchased this around 2015 at a Columbia directly-managed store for 24,000 yen. I bought it because Akihisa Hashitani, the representative of the mountain guide service Kifusha, whom I admire, reviewed it in a mountain magazine. At the time, it was a flagship model equipped with the latest Omni-Wick EVAP technology, a quick-drying function that prevented stuffiness inside the garment. I've only worn it a few times because the size didn't fit, but I remember being impressed that the inside of the clothes didn't get stuffy. I've forgotten the product name. Thank you.
