on the day i wore them it was  warm during the daylight hours (about 70 degrees) then the temperature dropped to about 40 degrees in the evening. they transitioned beautifully. i wore them all day with a loose tank-tunic then when it got chilli, i threw on a pair of tall boots and a long duster. they literally felt like i was wearing nothing, but kept me just warm and cool enough. i am definitely buying more of these.
