The Swiss Army OD Overpants we've just received are an awesome value we picked up in Europe. These overpants appear to have been worn very little if at all and are sized to fit most of our customers. Made from a 50% polyester / 50% cotton blend, you'll be pleased at how tough these overpants are when you wear them out in the field or in your workshop.
I wear a 34 waist and a 29 inseam. The fit is fine. These are unused. Gave them a wash and will keep them in the truck to use for over-pants if I need to change a tire.
I agree with others that these are too snug for overpants IF you believe them to be 38-40. If you wear 34 or so, they'd work as overpants. They are nice construction and great to throw in your car (like I did) for those emergencies - I wear 36 and these are TIGHT overpants but are better than trashing street clothes if you have a flat, etc. If you wear 30-34, you'd have a great pair of overpants.
I agree with the other reviewer that these are too snug for overpants. I've purchased these year ago and used them for that purpose and they were great. If you are under 6' they might work as over pants, but not if you are taller. Still good pants at a very low price.
Too snug for overpants (resulted in slight crotch seam blowout) for a 6'2" dude. But good as standalone work pants, or ski pants (with wax). Typical Swiss quality. Seems to have been previously used by a mechanic.
