Review: Great pants for motocross, not the best if you anticipate falling - Comfortable and fits well. This would be great for motocross/dirt riding where “armor“ is not needed. I did not find pockets for my CE rated “ armor” pads. As I hope to adventure ride, I anticipate falling quite a bit and really wanted something I could put a little padding into. So I’d give them a great review, but to be aware you cannot place armor in them.
Review: Alpinestar Top Notch Quality - It took almost a month to receive these pants, I purchased the matching top which came within a week but I had to return it because out of the package the stitching was already bad. However, these pants fit perfectly. Not true to size but it's always best to go a size up for these type of pants. I normally wear a 32 but got these in a 34. They still fit snug at the waist. I like the additional protection in the knee area. I also purchased the Alpinestar SMX boot in black. I have a few pair of Alpinestar boots and find all of them to be very comfortable. Great company, great products, great service. Very pleased with this purchase
