I am an awkward size; too tall, arms too long for my torso, legs too long for anything, and too skinny to fill out most jackets. When placing the order, I gave my measurements and was contacted over the phone to make sure I was cool with the adjustments that were going to be made to fit me. This included longer pads, and longer arms/ legs, which now cover my knees and elbows very effectively. I have full range of motion on the bike, and like they say- the more I wear it, the better it gets. Aerostich keeps more than 60 sizes in stock, so even if your body is a little outside the normal fitment, they've got you covered. The suit is designed to fit over your casual clothes, but even then it doesn't really feel bulky like I was expecting.
