I have a very hard time finding gear that fits - I've got long arms and legs. I have found that Olympia makes their pants with an "easy hem" for shorter legged ladies to easily have them altered. Kinda like Chaps. They have a side zipper that goes almost the full length of the outseam and velco for the remaining 6 or 7 inches to the ankle. Looking at the pants from a seamstress perspective, it wouldn't take much time to shorten them at all.
What I like is they are an acceptable length from the git go - they could be another inch longer, but I'm not complaining. At least when I'm in the riding position, there isn't a gap between my boots and my pants now! ; )
I've got their Mustang Jacket & Pants as well as their Air Glide II Jacket & Pants. I've been "divesting" myself of my other riding gear as a result. I've been using the Air Glide set more, as they have a cool weather liner for the pants and jacket. When it's really cold (under 40* - remember I'm in Texas) I wear a pair of jeans under the pants and a good fleece sweatshirt under the jacket and I'm pretty toasty.
I haven't done it yet, but I'm sure I could wear my rain suit over the whole thing and have another layer. However, until I get my heated grips installed and find a way to keep my feet warm, that won't be necessary. My hands and feet are the first thing to go numb and that will stop me in a hurry.
