Creighton GTwrote a review of Giro Ambient Jacket - Men's on December 30, 2018
Familiarity: I've used it once or twice and have initial impressions
As a Northern Colorado Front Range rider, I really like this jacket. I save it for rides in the 40's and below.
If it's in the 40's and sunny, I prefer a light base layer underneath. When it's colder, I play around with thermal layers and vests.
At 6'4" and 200lbs. the large size lets me layer and keep out the draft (there's no waist draw cord). If you don't mind starting your spin on the cool/cold side, this may be your jacket. Given that it is windproof, one needs to consider the heat he or she will generate.
My one concern would be the zippers: they're really fine like the zippers on some jerseys. I haven't had any issues, but I see myself using them a little more carefully then I do with other jackets, etc.
