The Terry Bella knickers were my favorite for many years. Sadly, they are no longer available, and the Bella Prima, while good in some respects, simply does not work on my short legs. The chamois is my all time favorite Flex Air, and the fabric is quite nice. However, the leg band hits my legs far below the wide part of the calf, and is so loose it flaps in the wind while riding. I have to roll the entire leg band up at the seam where it joins the leg fabric to prevent the flapping, and then there's really nothing to prevent the leg from riding up and bunching slightly behind the knee.
Lightweight tights when you want a bit more coverage.
