I have used the Alpinestars Sight mostly for bike park rides. The pant is a little tight in the crouch. Doesn't bother me much since I do not use padded underwear. Otherwise the overall fit is good. There is a lot of stretchy material on strategic parts. As well as durable ripstop where it counts. The pant is comfy and you can fit kneepads under without feeling restricted in the movement, at least not for downhill. A small front pocket for keys. A bit to small for a smart phone.
