If you're riding in temps where knee warmers are adequate, but find the droop to be annoying, you may find full tights to be too warm for you. You may want to consider knickers, such as these. Shorter than full length tights, usually with a chamois, and generally not as warm as tights. Personally, I find them great for the 50-degree range, but different folks have different tolerances.
