MTB-specific shorts seem to be currently made in the following guises:
- Shorts from special rip-resistant fabrics and strategically placed pockets, with no padding. Rider can size up and wear padded liners (or road shorts, or road bibs or liner bibs), underneath if they like.
- Shorts as above (#1), but sold bundled with padded liners similar to road shorts, but the liners are made from a fabric so thin they resemble undergarments more than road shorts.
- Shorts with padding built into the seating area, but that are not to be worn "commando". Athletic or some kind of undergarment go underneath.
- (For men) Shorts with padding built into the seating area (as #3 above), but with a sewn inside mesh akin to that found in swimming trunks. At least one maker seems to have devised a mechanism (velcro? snaps?) to make the liner detachable, perhaps in the interest of washing one part more often than the other, or replacing it.
Are these categories, especially #3 and #4, accurate? Did I miss any?
This is a sequel to an earlier question.
