“Surprisingly warm”

“I was skeptical about this jacket at first, because it is so lightweight. But I have warn it (over thermal layers) on bike rides when temperatures were in the 40s, days when it started to rain, and on a hike to the top of a mountain where the windchill was in the teens, and it has always kept me warm. The sleeves unzip so you can vent the body heat without losing the warmth on the arms. even the thin hood that tucks into the collar is warm. And the Descente cycling under-helmet hat matches it perfectly.”
