Great leather pants that offer great protection with good air flow and fit. I'm 5'7" around 155 lbs and wear a 48 Euro/ M Japan, which gives me a race fit. I tried the M Wide Japan originally but they were a little bigger than a comfort fit. The leather is nice and soft which makes these feel broke-in right off the bat. Pair these with the Arrow jacket and you have a great 2 piece suit for the canyons or track. There are only two small complaints on these pants. One is having only a zipper in the fly area. Two is the adjustment straps a very close to the circumference zip which makes it a little more difficult to attach the jacket. Other than those two small issues these are great pants to use in a 2 piece suit. If you already have the Arrow jacket I highly recommend picking up these pants.
