I used this for dirty work in the winter. I haven't used it this winter. The size is 3L. There are zippers at the toes of both legs, but they are stuck and don't move. It's hard to see in the photos, but there's a lot of oil and paint stains that won't come off even after washing. I don't think there's any severe odor, but it's a matter of personal sensitivity, so I can't guarantee it. The hood is detachable with buttons. There may be other problems, but please prioritize the actual item. No claims, returns, or refunds, please. Shipping will be in a cardboard box with simple packaging. Thank you.
