I'd always worn a lightweight fleece when climbing or hiking in cool or windy conditions. Since buying the Transition Featherweight Zip Tee, I've climbed and hiked four days with temperatures ranging between 37 and 50 degrees and light to moderate breezes. It performed well alone but when the temperature was lower, I added a midweight insulated top. It's an absolutely great product.
