    This review is for Alpinestars Track Leather Pants
    Track pants - Derek   Recommended by Reviewer: Yes
    Pros: Protection is great tested haha
    Cons: Tight fit, severe con

    I wear a size 34 jeanspants, so I ordered a 36. They are way too tight, I have to suck my stomach in to get them to sit. They are tight in the thigh areas as well, youll need a size bigger than the size chart says.Crashed in these on a track day around 80mph and nothing rippednothing even shows the inner layer of leather so i continue to use them


    This review is for Alpinestars Express Drystar Waterproof Over Pants
    Waterproof Not so much. - Nick   Recommended by Reviewer: No
    Pros: Comfortable, zip into most Alpinestars jackets to make complete suit.
    Cons: Drystar is not Goretex, and these are not waterproof.

    What Drystar will do is keep you mostly dry in light rain conditions, but if you're a touring rider and you're going to be passing through some actual real rain, then you'll still need a rainsuit with this kit. It isn't waterproof despite what the advertising claims. What ends up happening is water saturates the fabric and eventually has no real trouble getting through the membrane, leaving your clothing underneat soaked.What I do like is that they fit well and the are comfortable for minor inclement weather, on hotter days I usually wear shorts underneath.Overall, I own these because I got them for a steal, I would never buy them again, and now that I'm doing a lot more serious long distance riding I'm going to invest in better gear.
