Alpinestars Megaton Drystar Jacket 4.3 5 19 19
Best jacket i ever had this really a complete 3 season jacket, i've ride till 8°C with all the liner and never feel a bit of cold, on hot days on summer, just remove everyting inside and you have a tons on airflow . great protection. the only downside for me is when all the liners are in, on position on the bike, the integrated backprotector pulls a bit on the back of my neck December 11, 2014
Great jacket for the money I ordered a size Large. It is a little roomy on the belly, but thats fine if I want to wear a sweater under it on winter. The jacket is comfortable, well made and good looking. My only complain after using a mesh jacket, is that the air flow is adequate on summer, but not the best. December 10, 2014
Perfect All Year Round! I purchased this jacket using the size chart (small) and it was a bit snug. But I guess that isnt a downer because its not supposed to be loose. The arms have 3 adjustable tightening straps with 1 at the biceps, 1 at the triceps, and 1 at the wrist. There is a layer of insulation and a layer of a thin rubber-like material that can be removed. There is also some soft padding that can be replaced with other individual armor pieces. The only downside is the same as many other reviews, if you wear the neck strap it presses into the bottom of your chin/top of your throat. All in all, this jacket is convenient, stylish, and pretty weatherproof! I would definitely buy another. December 5, 2014
Awesome All-Season Jacket This Jacket is fantastic. Hottest I've had it in was about 75-80 degrees with the liners out and the vents closed its not to hot and me at a comfortable temperature. The coldest I've had it was at about 35-40 degrees in rain with the liners inserted. I was warm and it kept me dry. The harder outer layer breaks the wind very well.and having the adjustable neck is great to keep rain from dripping in. Plus the jacket looks awesome. December 1, 2014
The Jacket is AWESOME!! I like it a lot. Thank you guys. so fit and stylish. Shoulders, arms areas are so fit and has no bulkiness that most of jackets do which makes it very comfortable to wear. November 23, 2014
Great first jacket As a first time rider, I chose this jacket because of its four weather versatility, simple design, clean look, and armor. Staying in California, you can encounter all kinds of weather. I've had this jacket since AUG2014. -LA summer 90F+, good airflow for the amount of vents provided. Works best at speed -Early morning commute between 60-70F, good insulation from wind chill at 60 mph. I closed all vents beforehand otherwise I would shiver. -No rain, will evaluate when the time comes. -Zipper, I haven't had a problem with it as to the other reviews. Operates easy enough with gloves. -Collar, I don't mind it when the jacket is zipped all the way up. It reminds me of the throat protectors I had to use with the IBA (USGI Body Armor). I dug a little bit around my throat but it "breaks in" after a week or so. September 25, 2014
Beware the zipper.. I bought this for my boyfriend last Christmas. He wears an extra large and it fits him spot on (he has a 42" chest I think). It keeps him warm and dry for his short commutes in the rain and looks super-fantastic as well. The issue is the outer zipper. It seems to be very small in comparison to other jackets and comes apart at the bottom on him. This has happened several times now while he is riding. Will likely have to get zipper replaced with something that holds in place. I wish I could recommend the jacket. This is disappointing and would be a great jacket if it wasn't for that issue. July 23, 2014
Good but not great Fits true to alpinestars sizing guide. The biggest issue I have is with the collar, it's uncomfortable and tends to dig into my neck while riding. I have to unzip the top and unbuckle the collar to ride with any comfort. July 2, 2014

A shopper asked: I know the question about water proof has been asked, but I want to clarify. It seems to imply that the liner is what makes this jacket water proof (or resistant). I want to know specifically if it can handle some rain without a liner in it. I would not expect it to handle an all day or very hard rain, but if I get caught out in a short duration light rainfall, will it keep the rain out without the liner?

Also, does it have a zipper for attaching it to the pants that mates with the Andes pants zipper that is nearly 360 degrees?

Philip S: This jacket will NOT keep the rain out without the liner. It's just like any other textile jacket without the liner.

I usually keep the liner in my backpack on days with a small chance of rain & if it does catch me while out on the road, I just pull under some shelter and zip the liner in. Putting the liner in took a little while to get used to since there are several zippers & I kept getting them mixed up and thought that there was something wrong with the jacket. I was just using the wrong zippers. On one side of the jacket, the rain liner zipper is on the rain liner, on the other side, the zipper is on the actual jacket. I don't understand why they made it that way, but whatever, it works & keeps me completely dry!

It DOES have a zipper in the back for pants.

John H: Yes, it is water-resistant without the liner. I've ridden through some moderate rain without the liner, and it's done a fair job. And yes it does have a waist zipper -- I've connected it to the Astars Switch pants with no issues, and I assume it'd work just as easily for other Astars pants. Really love this jacket. It even works well in warmer temps with the vents open. May 26, 2014

Nate B: In my experience Not really. The outter shell is like a canvas material and is great for spring riding but it in rainy riding conditions soaks up water enough that you will feel damp if not wet with out the water proof liner. Good thing though is if its a light passing shower your riding through with out the liner, the jacket dries up pretty quick. Hope this help. May 28, 2014

Jim S: Thanks for those quick responses. I am getting ready to exchange the Andes pants as the sizing was not right, even after consulting with the guys at Revzilla. Fortunately, they are great to deal with - I won't mail order riding gear from anyone else on line! Looks like I'll be ordering a new Jacket soon too. May 26, 2014

Nicolas V: The jacket is quite thick with 2 liners. If you leave the rain one out, it will still take a significant amount of rain to soak you. I rode in pouring rain for about 10 min and was still dry.

I can't tell about the pant fitting, I do not own these pants

A shopper asked: I'm a fairly tall guy about 6'3" 6'4". I'm just wondering if the jacket will come down my back far enough to keep me warm and dry. instead of riding up like some jackets do? Jun 11, 2014

Jon R: I'm 6-feet and wear the XL; as Michael A said, it hits about mid-zipper on jeans. It's definitely not a sport cut jacket. I'd say it is in between sport cut and touring. Unlike touring jackets I've tried, this one doesn't bunch up in the front when sitting, and unlike sportier jackets, it doesn't ride up in the back. I think it is a very good length. Note also that if you have appropriate pants, there is a zipper in the bottom rear so you can zip the jacket and pants together to eliminate any worries about the jacket riding up. Jun 13, 2014

Philip S: You can buy a spoiler for this jacket that comes down about 6-8 inches more in the back. Sizing on the spoilers are weird though. I believe I had to buy a Large spoiler to match my Medium jacket. That doesn't work with all sizes though but you can always return for a different size and only have to pay return shipping for the original item. Jul 1, 2014

Michael A: I'm 5'8, the jacket comes down way farther then some other jackets I've owned, for me it comes down to about mid zipper on my regular jeans. For someone who is 6'3, depending on how long your torso is, it's probably gonna be right on the belt line of your jeans.

Hope this helps.

Andrew H asked: I noticed this is listed as an all weather jacket. Would it be comfortable when it gets up to 75-80F? I would love to be able to where it all year. It's fairly mild where I'd be wearing it, I'd say from mid 30s in winter to 85F in summer. Dec 9, 2013

Jon R: I live in Texas and have been riding in 80+ F degree weather for a few months now; lately we've seen temps in the low- to mid-90s. I've found the jacket to be acceptable in the 80s and not too bad in the 90s but then my commute is only around 20 minutes.

Unlike say a mesh jacket, this jacket doesn't breath well (but then you're also better protected), so it is all about the vents -- they're located in good positions and they do work, but they're heavily depending on you moving and flowing air through them; if you sit still in this jacket too much (as I have to in traffic sometimes) you do start to get uncomfortable. I'm actually looking at summer mesh jackets right now as the temps around here are only going to get higher and I can see this jacket not really working well once we're regularly in the 100s.

However, I will say this jacket is very good in cooler weather. I wore it down into the 30s and 40s on numerous occasions this winter and was not uncomfortable; in fact, I was very impressed. I recommend using the winter liner that comes with it; anytime I tried using some kind of pullover or other garment in its place (even multiple layers) they simply didn't compare to the default liner's ability to keep out the cold.

Justin B: Yes, I bought this jacket when it was in the 80s and 90s, and was so comfortable with the ventilation system opened up. Airflow design works really well. And now I am wearing it in the 30s and 40s and it keeps me very warm. Would recommend to anyone. Great jacket! Dec 21, 2013

A shopper asked: Does this jacket have the snaps for the Alpinestars race back protector? The race back protector is the one that snaps to the jacket instead of being inserted in the pocket. Oct 5, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
George M: No snaps here guy. Just the standard pocket design. Also, this isn't really a race/track styled jacket. I'm confident that the back protector you've mentioned would fit in the pocket provided on this jacket.

I hope this helped you.

Ride safe.......

A shopper asked: Is the chest armor upgradable too? The description only mentions "CE certified Bio Armor back protector insert available as accessory". Alpine Stars offers some nicer chest pads and I'd want to know if they will fit in the compartments on the "Megaton" before buying. Sep 17, 2013
