Nice, inexpensive rain jacket with dropped tail to protect the rear-end. This is NOT a Tyvek jacket as described by some reviewers; I've worn tyvek biohaz suits as an evidence tech at crime scenes, and believe me, they are not breathable. My experience thus far is that this jacket breaths only slightly less than my whisper-weight nylon windbreaker. Unlike the windbreaker, I hope it will keep the gritty-filthy road film from soaking through three layers all the way to my skin so I'm not a skunk with a black stripe up my back on my good clothes when I get to work. Have worn twice on a rainy day where I managed to be just ahead or behind the rain the entire rides, so am unable to rate its "waterproofness" yet. But pluses so far - light; bright!; reasonably breathable when completely zipped (and I adjust cooling via the zipper, which might not work so well when pedaling into a driving rain); hood fits over helmet (don't understand a biking rain jacket without a hood - don't like wet street dirt/grit/mud/oil on my neck or in my hair, anymore than I like it on my clothing or skin); plenty sturdier than described by some other reviewers (not going to rip it riding on city streets or putting on, taking off); nice bag of same material to store it for protection when tossed in pannier; and cheap, cheap, cheap! I cannot see paying hundreds of dollars for jackets that are gonna get covered in grime. . . 01-25-15 Update on above - Have now worn the jacket in a brisk drizzle and a light rain; (just missed the heavy rain). The jacket performed fine, no rain got through, and let me keep a comfortable temp, neither too hot nor too cold. Once at work, I put the jacket on for a few seconds while in the shower to wash off the road grime, and the water did not get through to the inside even while in the shower. I'm seeing some people complain about the jacket not being warm enough. I classify this as a rain jacket, period, with the advantage of being breathable. To get and keep correct body temp while biking, I wear the correct weight and number of layers of clothing beneath the jacket, same as I do with my windbreaker. So, if you're too cold or too hot, you simply need to adjust what you have on underneath the jacket. Still VERY satisfied and still just waiting for a good honest rain-rain to give it the five stars. Right now, I put it at 4.5 stars. 06-20-15 - After an unusually wet May (record setting) in Phoenix, I've now been in a full-fledged, soak-your-clothes, flood-the-roads rain in this jacket - and it performed GREAT. No rain got through; the jacket continued to breath; the road-dirt skunk stripe stayed on the jacket, not on me; and a quick rinse of the jacket in the shower cleaned it off completely. I've worn it into the high 80s and just moved the zipper down lower for more cooling and I still stayed dry. Now, the temps here are currently 115 degrees in the day - once the monsoon hits and the temps remain over 100, the jacket is probably going to be too warm for me to wear in the rain. I've have to go back to wearing a throw-away shirt and showering afterward to get the mud off me. But the jacket is holding up great and has been tumbling 'round in the bottom of my bike bag with other stuff bouncing on top of it for seven months, so it's a five-star inexpensive KEEPER. 12-28-2017 - two more years, and jacket still going strong! Quite possibly the best 30 bucks I've ever spent. 04-04-2019 - I have got to buy another of these as a backup before they are no longer available. Still using, still in same shape as the day I got it, after five years of tumbling around inside its little bag at the bottom on my pannier. I think it is basically indestructible, so long as you don't try to run scissors through it. 12-30-2020 - still wearing it, in same shape as day I got it, bag is getting a little worn. Most recently, worn biking in a driving rain where my leather shoes soaked through and ran over, my socks ringing wet, my bike pants wringing wet . . . . but I was bone dry under the rain jacket!! 12-12-2022 - Bag is looking really ratty now, but still the rain jacket is going strong! I got about as much rainy riding in two years as the previous one (pandemic), but still loving the jacket and the price. When the bag gives up the ghost, I will be buying another one of these as backup for when the jacket also finally gives up the ghost.
