This is a mont-bell Superior Down Vest. It's a standard and popular inner down vest from mont-bell. It's very lightweight. I bought it but ended up not using it, so I'm putting it up for sale. The retail price has been increasing, and it's currently 12,300 yen. mont-bell doesn't have sales, so you can generally only buy it at the regular price. If you're looking for one, how about this great deal? 【Condition】 Brand new, with tags 【Product】 mont-bell Superior Down Round Neck Vest Model Number: #1101505 Color: Black Size: M 【Sizing】 The following is just my personal opinion. ○ I'm 172cm tall and weigh 64kg, with an average build. The size is not too big or too small, it's the perfect fit. I bought it to wear over a dress shirt in the office, and I thought it was just right. I think it will fit people who prefer a looser or tighter fit, and those who are a bit bigger or smaller than me. ○ Although it's new, it has been handled by a person, so please refrain from purchasing if you are very particular about condition.
