Dissapointing
"Disclaimer, I have not yet taken this out on any high intensity outings (hiking/biking). While it is definitely ultra-light, it is not worth the cost. My initial use was on a walk under a rain shell on a 50 degree day and it didn't seem to do much. Even expecting it be a comfy layer to keep me warm when sitting at my desk seems to be a stretch. It does fit nicely beneath other layers, but so would a long sleeve shirt."
