Vintage 1970's Arctic Cat snowmobile suit

Vintage 1970’s Arctic Cat Snowmobile suit. This appears to a unisex size Small or Medium, as there is no size listed on the suit. The inseam measures 22” inches. The measurement from the armpit to the to the bottom of the leg of the suit is 40” inches. All buttons and zippers work perfectly. The belt is in excellent condition. There is some paint wear on the buttons. There is also some minor wear on the inside left armpit. The collar has a 1” stain that won’t come out. I just washed this, and used Shout pre-treat stain remover on this, and it won't come out. Please see the photos. This is clean. Freshly laundered. Does not smell, and comes from a smoke free, pet free home.
