We didn't mean to exclude you guys
Fortunately for you the industry has been a bit more kind about your long legged predicament. While a 40" inseam is not common it is not impossibly long.
Two questions for you first - have you ever tried to buy "Long" or "Tall" snowboard pants? If so what brand and how did they fit. Second - when you go to buy regular pants do you buy 38W/40L or is 40" your measured inseam?
Remember, just like with the girls - there is a pant out there for you and we will find it! Don't get discouraged and DON'T settle!
