Good Protection, Great Fit
I have both these and the soft foam padded shorts from Alpinestars. The MTB Bionic give a significant amount of protection and feel like they will protect me well the next time I take a digger. The mesh is super breathable so getting swamp butt while riding is probably not a concern. The only grip I have about the shorts is the tail bone protection. Its a little to hard and sometimes is noticeable while in the saddle pedaling. Other then that one gripe, the shorts are great and are an example of the quality products Alpinestars produces.
