Robert B.wrote a review of Louis Garneau Spire Convertible Cycling Jacket - Men's on June 1, 2018
Familiarity: I've used it once or twice and have initial impressions
Fit: Runs small
This is another high quality product from LG. It has a snug fit but the material is very stretchy so you have plenty of freedom of movement. The sleeves are long (intentionally) to keep you hands warm if you want to pull them past your wrists. Also, there are bits of reflective material hidden everywhere plus a hole for your headphone cable in the center pocket. Nice touches.
Be aware that, when the sleeves zip off, this is NOT a vest but a short sleeve jacket. There are fleece-lined elbow-length sleeves that do not zip off, so it is still going to be fairly warm with the sleeves unzipped.
