Alpinestars Megaton Drystar Jacket 4.6 5 20 20
Great Jacket. Great value. Great protection. Great Airflow I really like this jacket. I will say it gets a little warm even without the liners in it during the summer but its really not bad at all. I am 5'10" 32 inch waist, athletic build. 170 pounds and I bought a Large. I actually went to a motorcycle store in my area to try on a couple sizes and I would recommend you do the same. In the winder when I put the liners in, I also have enough room for a long sleeve shirt so I think I will be plenty warm especially with a scarf. Only wish I have is that it came with a better back and chest protector because it came with foam inserts and that is kind of a rip off. Especially considering the price of the aftermarket inserts.... May 24, 2016
Great Daily Riding Coat I wear this coat to and from work everyday. So far I like everything about it! It keeps the wind out on cold mornings, and I can unzip the vents for my ride home. I ride in Texas so this coat can be a bit overkill on a hot day. I usually ride without the thermal and rain coat layer due to hot temps (they are totally removable via zipper and clips in the arms). The shell is perfect on a chilly morning with a sweatshirt! Pros: Excellent elbow and shoulder pads Pretty waterproof Thick synthetic outer shell Flexible yet stiff enough to feel safe Comfortable Looks incredible! (doesn't scream "tool") Zips with alpinestars pants for rainy days Cons: If you have a large Adam's apple like I do, the top of the coat above the zipper is stiff and hurts (even though everything around it is really smooth) The chest/back padding could use a little improvement. They're removable so it can easily be swapped for better alpine star padding All around this coat is awesome! I won't buy any another coat unless I take a spill and need to replace my equiptment. Buy this coat if you want protection and flexible options (: For reference I'm 5' 11" - 135lbs - skinny as a twig and I am definitely a large March 30, 2016
Great Jacket Amazing jacket, great look and has many features along with a wide variety of uses. February 2, 2016
Stiff and Oddly Sized I have owned many Alpinestars jackets and have liked all of them (except this one). While there is ample room in the arms and chest, it is very tight around the abdomen (not so in my other jackets). The main zipper is rather weak (like all Alpinestars jackets), and unless you ensure the zipper is properly seated (with great effort), it will come apart. The material is very stiff and restricts movement. On a positive note, the jacket is rather warm. While I can use this jacket on my touring bike, there is no way I can use it on my sport bike.

Great jacket for the money Pretty solid jacket for the price. Looks amazing and fits well. May be a little on the small side but is still very functional. Love the jacket and would recommend to anyone looking for something in this range. January 25, 2016
Comfortable longer fitting jacket for every season. I have only worn it in the winter months no wind penetrates. It has 3 layers which I pealed away to try on the jacket with each layer and it fits comfortable with any combination. I'm 150lb 5'6 pretty fit and the large fits snug and safe. Can't beat the price for a 3 in 1 jacket. January 21, 2016
First Impression as a Winter Jacket I just bought this jacket specifically for winter riding and my 30-45 min commute to work. This morning it was 32 degrees and it kept me warm. No BS. Top speed was 90mph. Underneath I wore some cheap thermal long sleeve from Gap I think. Maybe felt a slight breeze on my forearms but I was wearing some oversized leather gauntlets by Harley Davidson. Couldn't really get them on tight enough. the Jacket fits like a GLOVE (Medium). I'm 5'5, 155 lbs. I don't have the broadest shoulders in the world but I'm athletic and have a thick chest. I was worried that it would be too snug through the shoulders but that's not the case. This is without any inserted KR1i back protection, etc. The sleeves hug my arms but don't squeeze. You could probably get away with wearing a few medium layers underneath or 1 big sweatshirt, etc. The raised protective neck collar is nice but doesn't keep out the wind/cold. You will need a quality balaclava or neck warmer to be fully protected. Also, the waterproof/thermal liner closes a bit tight around the neck. I'm leaving the velcro undone when I ride. The jacket's outer shell neck flap is good enough. As far as durability goes.. it seems to be made well. Designed in Italy but manufactured in Vietnam.. so we'll see how it holds up. I'm being gentle with the waterproof liner when I zip it up. I'm satisfied. Monster 695 Multistrada 620 January 12, 2016
Definitely recommended for 3/3.5 seasons. I bought the Alpinestars Megaton specifically for fall, winter, and spring, as I already own a mesh summer jacket. I paired it the Andes pants and Klim Inversion insulated gloves, also great products. The Megaton jacket is very well constructed (heavy) and feels like it offers good protection. It looks great too, but not over the top. So far I've ridden in the low 40's at highway speeds and the jacket offered good wind/cold protection (wearing a thin thermal long sleeve underneath). A little bit of wind/air makes it through the vents/zippers at speed and the neck collar, but not enough to make you chilly. I would say below 40 degrees you'll want to wear some heavier undergarments. I am 5'9" 170lbs, 32" waist, 41" chest and the large fits perfectly, if a tiny bit loose, good for wearing heavier thermals. Btw, not many stores carry the selection of gear revzilla has, so having these detailed video reviews was very helpful. Keep it up guys... November 25, 2015
