Alpinestars Megaton Drystar Jacket 4.6 5 13 13
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
Very Safe Feeling Jacket First cycle jacket ever. After hours and hours of research I decided on this due to a few reasons: 1. Needed a jacket that wasn't too hot or too cool in the WI weather I live. 2. Must be able to upgrade a chest and back protector. 3. Must be good protection for a dual sport bike wipeout in dirt or pavement. 4. Mustn't be too bulky or too light. --This jacket has the best of both worlds. Adjustable vents in the arms. Removable liners depending on the weather. I was warm in 80 degree weather but that's to be expected. Does well in 45 degrees but I wasn't going over 30mph so no idea if I'd freeze doing 60mph. It's snug enough to feel protected but not at all baggy or bulky. Most of all I feel safe when wearing it. It does fit a bit small especially with the chest/back protector upgrade although you do not want a loose jacket sliding all over the place if you wipe out. Once you have it on a few minutes it feels great. I really have no complaints about this jacket. Very happy. If it helps anybody, I'm 5"9' 165lbs, athletic build. I purchased a medium size.

Best All-In-One First and foremost, this is my very first Motorcycle Jacket and I wanted something that was durable and able to used in different types of weather. I'm in California and it doesn't rain much here, so the ability to remove the waterproof liner was a huge plus. The thermal liner is removable also. There are plenty of vents, and the style is very nice. The non race cut was big for me, because I'm not slim, and having a stylish jacket without being tight on you is great. Bugs also wipe off pretty easily. I love this jacket. October 5, 2015
Very nice jacket for the money I have had this jackit for weeks now and done a few hundred miles in it. Style, yeah its got it, I got the white/back version and I have gotten more complements on it then I have any other jacket in the past. Fit, yes it is a fuzz small I float between an L and an XL in alpinestars, got an XL fits perfect with both liners installed. it is a bit big with out liners but that is to be expected. not big enough to feel like it effects the protection factor. Comfort, I can't speak to its all day comfort, but on my 25 min ride to work I don't feel restricted in the arms or shoulders, initially I noticed the collar was a bit more bulky then my last jacket but I didn't notice it after getting on the road. Doing highway speeds it does not flap around on arms or sides, the I had the collar pined back and I have no trouble with it staying put. Venting, does a good job of keeping you cool, not as well as a mesh jacket, you can feel the air being sucked out along your back. I was out in mid 90's and I was as comfortable as you can be sitting on top of a motor with a jacket on in the heat. With the liners in its warm, I'm excited to try it in cooler weather this fall. Protection, arms and shoulders are what to be expected from stock CE rated armor, the back and chest that come in are complete garbage, toss them and get the upgrade, that being said the armor pockets for the chest and back are much improved over my last astars jacket, the pockets feel tighter, allowing less shift of the armor. Features, Love the bicep adjuster, Tighten it down as tight or loose as you want to, easy to adjust on the move too. forearm snap I would like to see a third snap. thumbs up for waterproof chest pocket.

Order a size up!!!1! Listen to the other reviewers and order this a size larger than normal. I'm 5'10" and 200lbs. Mostly hover between L and XL. Got this thing in XL to be safe and It's REALLY small. I can't even wear the thing with the thermal liner. I refused to believe I needed a XXL when ordering, but probably should have. If anything else, I guess this gives me an excuse to lose a couple pounds. Weight reduction bro. May 29, 2015
Mostly great I first have to say I love this jacket. I enjoy wearing it, and it fits me great on my bike and off my bike. When I first got it, it was really snug. I had ordered the bionic air back protector, but hadn't put it in yet. I was really concerned it was going to be too tight. I'm 6'1", 220lbs, and have a 46" chest. My jacket is a 2XL. Weird thing is it seems that while the jacket doesn't "stretch" per se, it does seem like it relaxed a bit because I now wear it very comfortably with the bionic air back protector, as well as the bionic chest protector. The jacket flows more air than I would have thought. It's incredibly hot and humid lately where I am - 80's to 90's, and humidity is about 90% - and with just a tshirt on underneath, I'm very comfortable with liners removed. I haven't worn it yet with the quilted liner, but the rain liner works great - just keeps in the humidity too much. should be just fine in dryer climates. My only gripe with this jacket, and why it didn't get five stars from me is because the velcro around the neck is pretty weak. the neck flap is practically useless, and I think it's held to the jacket merely by the wind pressure when I ride. The velcro inside that holds the chest armor in place is very weak as well. the chest armor falls out of place regularly, which is a little irritating. Also, I own the blue/grey/red version, and it's definitely red. From the pictures it looks a little like orange, but it is not orange at all. And the blue is a bit more rich than the photo too. But all in all, I like my jacket. I also wear it with the Valpariso pants by A*s, and you'd think they were made to match. Interfaces nicely with the waist zip on the pants. May 19, 2015
Great Jacket! Only had this jackets for a few weeks, but so far I like it. It's a little bulky off the bike, but on the bike it feels great! I rode without either liner and it was chilly, so I hope it rides nice and cool for the summer! Haven't had a good rain ride but will update after I do. April 6, 2015
Great Jacket My daily commute to work takes me on the highway for about 15 miles each way and I ride in everything but ice and snow. I am 5'6" and 140 pounds and bought the jacket in a size Medium. The coldest weather I've worn the jacket in was about the mid 30's at highway speeds and was reasonably warm. I was able to fit a hoodie underneath it for one ride but it was a little snug around the neck and probably wouldn't try it for anything longer than the commute to work. Since I got it over the winter and haven't had a chance to ride in the heat, I can't talk about how well it vents. April 4, 2015

RevZilla Store asked: Why did you choose this?
Jeffrey D: I ordered this jacket one size larger. (L - XL) I had ordered originally as a Large but found that if was a bit small. I'm a 42R (American size) and the large is targeted a little smaller than that size. Nov 10, 2015
Nathaniel N: It's a 4 season waterproof jacket that looks amazing in black/white/red. Touring features with sport looks are exactly what I wanted. Oct 9, 2015
M D: Direct body venting coupled with waterproof baked in and a little longer length. Summers don't get too hot here in Washington, so this should hopefully stretch deep into summer for me. Jan 17, 2015
George S asked: How does the sizing compare to the Gunner WP? I bought a 2XL gunner which fit without the liner but left no room for layering with the liner on. If I switch to this jacket should I go up to a 3XL? Will removing 1 or more of the liners provide sufficient room in 2XL?

I am 6ft 4in, 240lbs for reference.

Grant G: I would definitely recommend going up from the 2xl. I don't have the gunner, but I do have the Megaton in a 2xl. It is snug on me now with all the armor - chest and back - but not too snug. I'd say it's a perfect fit for me. I'm 6'1", 230. I haven't measured my chest in a while, but normally I wear a 46 L in sport/suit coats. It sound like you might be a bit bigger than me, and I feel like if I wa any larger it would start to feel uncomfortable with all the lining, etc... Apr 27, 2015

Rich S: I am 6ft 4inches and 245 pounds. I wear 2xl in just about every shirt I own. I started with a 2xl and it wasn't even close. I exchanged it for a 3xl and still wasn't close. I now have a 4xl and it is good. Still a little snug with both liners in, but not uncomfortably so. Revzilla was great in exchanging them twice. Very happy with them! Apr 29, 2015

Jacob R: I'm 5'11 weight is around a 170 pounds. I went with a large with all both liners in thermal long sleeve T-shirt and sweet-shirt its a little snug. I was excepting that length is jest right on me. heads up on me the waterproof liner as no fabric on the collar so it not the most comfortable on the neck.

hope this is helpful Jacob

A shopper asked: How many grams of insulation are in the thermal liner?

Trying to decide between this and the a* bogota... Opinions?
Jul 6, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
Rich S: I have no idea how many grams there are, but I can tell you with the liner in it is really warm. Have worn it with only a polo shirt on several mornings with temps in the 40's and have been comfortable. With the liners out I have worn it when it is 80 with the vents open and am also comfortable. It's a great jacket. Jul 6, 2015

A shopper asked: I noticed the zipper for the pants is located on the rain liner? Can you confirm this? I would rather it be sewn on the jacket itself. Is this a good replacement for the DS Space jacket? I've had mine of six years and now it doesn't stop the rain anymore.

Chandler S: Looks like there's a zipper on both the liner, and the jacket itself. I haven't been in any serious rain wearing it yet but it has held up great in hot, cold, and some light drizzle. Oct 26, 2014
