Amfib Cycling Tights For 40f - 60f Weather?

Cycling tights for 40f - 60f weather? - amfib

Looking for a good pair of long duration, probably w / a chamois. I like Pearl Izumi tights Amfibi but seems more suited to a much colder climate (20 years - 40 years). So if anyone has any suggestions or Amfibi you think you are fine for the 40 - 60, let me know.

Thanks to you all!
