Assos never disappoints me, and these knickers (size small), were no different. I tried them out on 2 60+ mile rides in 49-68 degree temps. They were warm without roasting me, breathed well, and the wide soft waist band was perfect, no binding, no slipping down. The only slight drawback was the below the knee leg gripper. I found it a bit tight and I have really thin legs, so if you have muscular legs, this might be a tad uncomfortable. But for us pencil legs, it was just a minor annoyance. No chaffing behind the knee, or anywhere else for that matter.
