I wear this 3 season jacket virtually every day in New York; riding my bike, at the office, or heading out to dinner. I've even extended its usefulness into late fall by layering with a insulated vest. It's travelled halfway around the world with me; showing up for a meeting looking totally professional in 90 degree heat and humidity. I can't say enough good things about this jacket. I only wish NAU made an insulated version for winter riding. Fits true to size; the sleeves are long, but fit right when your arms are extended riding a bike. Buy one and you won't be sorry.
