I bought this jacket as a lightweight carry-on for a trans-Italian cycling trip. It's perfect for the unexpected rainstorm, though I would hesitate to use it as full rain day gear. Without a liner, moisture build up makes it a little close to the skin. Good product, well made, and at an excellent price.
It's bright, it packs down to the size of a water bottle, and it's pretty breathable. When it was cooler, I used it as a shell in the mornings to block wind and it did fine. In moderate temps, my torso managed to stay fairly dry, but my arms were still all sweaty. I'd say this jacket breathes better than most, but it still tends to hold some heat and moisture. I haven't ridden it in hot weather, but it would definitely be a sauna inside I'm sure. It's more of a cool weather jacket, or out shell for very cold weather. If you need rain gear for summer for anything more than an occasional rain, you'd better invest in a lighter membrane layer.
Still, good construction. Great fit. Decent, maybe just above average breathability.
I had been getting by with a low cost department store raincoat for several years, but decided to get a better one specifically for biking in wet weather. I liked the look of this one so I put in my order and got one. I was surprised at how light weight it is. It stuffs into an included stuff sack, and takes up little room.
I've worn other rain jackets that didn't have anywhere near the features this one has.The fabric is very lightweight, yet is also very durable. I vey much like the back vents that allow the jacket to breathe while still maintaining the rainproof quality I was looking for.I can see that I'll be wearing thhis jacket for a long time to come. And the high visibility yellow is awesome. I definitely got my money's worth!
