Love it!
I am adding clothes for my new hobby of bicycling as I go through each season now. It was time for something to block the wind. I wouldn't say it was that cold yet (late September), but the cold wind was becoming a problem in the morning. This jacket is great. I have PI shorts that have been good to me so I tried this jacket. I am tall and thin (6'3", 180lbs), with a 34-35" sleeve length. I would normally wear a L, but was able to try on the XL in a store and it was perfect. Not a spandex fit, but not baggy either. It fit my body and I still have room for a layer or two underneath (like a long sleeved underlayer or a 100 weight fleece ...or both). And the sleeve and back length are very good. The garment seems to be just as nice as any other Pearl Izumi products I have or have seen. This jacket was cheaper and seemingly a better finish than some of the competition I looked at that were made out of ripstop nylon (the same thing my parachute is made out of). And the beauty of a shell like this is you can take it off and stuff it just about anywhere you have a pocket if the weather warms up. It is thin and light but perfect for the task at hand. I didn't buy it for (and haven't tried it in) the rain though. The color makes me feel more secure on the roads too. I live and ride in Manhattan and I want as much impact deterent as I can get. The blue looked nice too but In the end I chose the day-glo for visibility. I've only had the jacket for a few weeks, but I love it. I will be looking at other PI products like softshells as the next season gets a little closer. Thumbs up!!

bought it for a cycling trip in northern new hampshire
It was a particularly a wet and cool season this summer in northern New Hampshire. I strongly recommend this jacket to anyone who is looking for a jacket for the cooler days.

Can't Beat the Men's Zephrr Jacket for the Price!
Comfortable outer wear for October cycling in New England. Comfortable fit in good weather and keeps you dry in light rain. Can't beat the Zephrr Jacket for the price!

Good windbreaker for the price
Fit: Medium is perfect at shoulder, slightly tight around torso even for a slim male; length is perfect for cycling. (Note: I have other Pearl Izumis and they're all a bit tight around torso -- for men & women alike.) Comfort: Lightweight, comfortable material, feels good wearing on off-road single tracks. Appearance: Understated yet technical and stylish. Performance: Breaks the wind chill, can't complain. Price: Okay price for a basic cycling windbreaker jacket.
