Have been wearing this jacket now almost daily for about two months, but it's increasingly spending more and more time in the closet. Overall quality is okay, but I can detect some fraying around the cuffs. It's not a piece I would expect to last a particularly long time. I bought in black/blue, and the zipper is neon blue, didn't quite realize that in the picture. The two different shades of blue don't work perfectly together.I've been using it for running and everyday use both by itself and as a base layer. I'm a little too tall for the jacket, really - I'm 6'8 - so I think that's influencing my opinion a little, but when running it doesn't really work as a windbreaker. Sure, the wind doesn't go right through it, but it's not the level of 'wind defense' I pictured.Otherwise I don't have issues. It does what I wanted it to, but it doesn't do it quite as well as I'd hoped. I paid $45 here on amazon, which is good value, but would avoid this at anywhere close to full retail.I bought this jacket for fall weather cycling in northern Minnesota. This jacket has impressed me. I'm 6'-1" tall and about 175lbs. I bought the large and it fits perfectly over a compression base layer. I rode this the other day in 40 degree (5 degrees celsius) misty weather into a 10-15 mph (16-25 kmh) wind and I got pretty wet during the 20 minute commute to work. The water was dripping from the visor on my helmet. Gives you an idea of how moist and windy and cool things were. The jacket has performed great. I was dry and I even had to unzip the front to "cool" down during the ride. I was fortunate to get this jacket at a great price of $45. That's about what I feel this jacket is worth. I think the $120 retail is a little over the top. If you can get it at a great price, you won't be disappointed with this jacket. The zippered chest pocket is a great addition. UPDATE: It's November and I've had a few months of riding with this jacket. For my commute to work I've used this jacket in 16F (-9C) temps with just a compression base layer underneath and it performed great. Great jacket.Liked the way the package came in, small but not stuffed. The jacket is awesome and as expected. Windproof and of good style. Fabric feels much thicker and like an actual technical fabric than like a rain jacket. I bought it so I can put it over my leather motorcycle jacket as a wind barrier. Yet to test it while riding the bike at highway speeds. I am 6'1'', 185lb and I got the XL to wear over my other jacket. Would probably be OK with L if I were to wear it just over a sports shirt. The fit is on the slimmer side so if you like loose fit then XL might serve you better.Got this jacket the other day to replace my older WindWall jacket and I love it. The colors are bright and it really blocks the wind. I am 6 ft tall and weigh 230 lbs and the XXL fits great.
