I rated them excellent because they are excellent protection. Last ride without Bionic shorts: crashed hard, very large deep bruise on left thigh. First ride with Bionic shorts: Crashed on left thigh (still healing), never felt a thing. No new bruising. A wider waist band would be nice- some rolling of the waist band. Wider leg bands would be more comfortable. The lower left leg has some chafing (from stitching? ) I have not checked it out yet. It is the only product I have found with the required protection.
Great protection on the thighs and tail bone but I wIsh the hip protection would be thicker/larger/better. Very comfortable and breathable. The little tailbone piece actually makes long rides more comfortable. It is a great product but the reason for only 3 stars is that for a hundred dollar bill you should have the best underpants out there and these still require separate hip protection.
