This is the Mammut "Masao SO Jacket." It has a slim style and a beautifully standing collar, making it very cool. It also has stretch and is extremely comfortable to wear. [Product Information] ○ Item No.: 1011-00460 ○ Size: S (Asian M) ○ Color: Black ○ Original Price: ¥30,240 [Condition] ○ Only worn a few times for commuting after purchase, and I think the condition is almost like new. ○ I think the neck, chin, and wrist areas, which tend to get dirty in used items, are also clean as shown in the photos. [Size Feeling] The following is just my personal opinion. ○ I am 172cm tall and weigh 64kg, with an average build, and the size is neither too big nor too small, but just right. It looks good even just worn over a T-shirt, and you can also layer a sweater underneath. Because it has stretch and a double zipper, I feel like the size range is wide. I think people who prefer a loose or tight fit, or those with body types slightly larger or smaller than mine, can wear it without any problems. ○ Athletic Fit ○ It has a slightly slim and stylish design. ○ According to the manufacturer's specifications, it is for people 167-173cm tall. [Other] ○ It is stored in a closet, hung on a thick hanger. ○ Non-pet, non-smoking environment. ○ Please refrain from purchasing if you are sensitive to used items.
