Lightweight Warmth
"Perfect either as single layer or used as a base under shell. Used for 37F run and kept body temp perfect. The neck is perfect size when zipped up. Just snug enough to keep some warmth and unzip if you need to vent."

Light fabric that breathes and will keep you warm
"This shirt breathes well and well not get sweaty. This alone keeps me warm to just above freezing, but anything below that requires a vest too. If it’s in the 40F’s, this is my go-to shirt. The zipper can be undone if you start to get hot."
Solid base layer
"Typical rabbit super lightweight comfortable shirt. Fleece provides some extra warmth but not likely to be great in sub zero temps. Serves my purpose in the PNW perfectly though. I'm 5'11 180lbs and size medium."
Nice top for winter mornings
"Top is comfortable for a cool fall or winter morning. Love the color too"
Tall Collar
"Love everything about it, except the collar is too tall."
