These overalls are part of the US military's extreme cold weather clothing system, designed for layering. I purchased these deadstock (new, unused) overalls from an online Rakuten shop and wore them a few times as overpants indoors for one season. They use Polartec Classic 200, a highly insulating fleece material. The full-length double zippers on the sides and the adjustable elastic suspenders are functional features that also serve as design elements. Size: M-REGULAR Color: Black Waist: 96cm Inseam: 59cm Leg Opening: 22cm Please note that these measurements are approximate due to being taken by hand. I will fold them as compactly as possible for shipping. I am sorry, but I am not accepting price negotiations. I will not be able to respond to comments regarding price reductions, so I appreciate your understanding. Thank you. *Returns and refunds are not accepted.
