"Superlight jacket to take the chill off."
I have used this when mountain biking now that it is warming up a little. After a big climb and you are covered in sweat on a night ride it is very nice to pull this very light and compact jacket out and cover up before the decent. The mesh venting on the sides lets it breath very well yet block the frontal wind. Sleeve length is good. I did find the body of the jacket just a little short but then I am 6'5" and have trouble in this area with most clothing.
Great lightweight jacket for being active. I've found Arc's Celeris and Accelero (former version, about to be superceded by a better-fitting one) to be too baggy, despite the claims of "Trim" fit. The Incendo delivers on its promise. It's trim without being skin tight. It wards off weather. It breathes well because of ample mesh panels. The stash pocket is nice except that my hand will rub on the zipper during my arm swing. Not sure the hem cinch is necessary. It, too, can be a slight irritant. But, all in all, it's great. Collar is just high enough to keep out weather and is contoured to the neck. Elastic cuffs are just right. Sleeves are long enough without being extra roomy.
