M-51 Over Pants. This is a YMCLKY original reproduction, faithfully recreating the distinctive silhouette and details. I purchased it new and only tried it on. Although it didn't come with product tags or price tags from the time of purchase, I bought it new from Rakuten Ichiba, so it is definitely new. Although the hot weather continues, I think these will be useful as they are authentic military pants that can be worn even in the warmer months. The size is M-Regular. The actual measurements, quoted from the shop website, are as follows: Waist: 94cm Rise: 38cm Inseam: 64cm Thigh Width: 38cm Leg Opening: 20cm
