Alpinestars Tech Jacket Spoiler 4.4 5 7 7
Many Problems Finally getting around to writing this. Purchased in November 2014. Another riding friend of mine has a spoiler from a previous year and it fits his Atem very nicely so I decided to get one too. Definitely helps keep you warmer during winter riding and I have removed it for the summer. My issues with the spoiler is that when attached to my T-GP Plus R Air or my Celer, it hangs down farther than it should and looks a bit sloppy. The closest I can compare it to is the coat tails on the old-timey tuxedos. It nearly covers my entire butt. Essentially its a couple inches longer than it really needs to be. Turns out, this issue is more with the zipper attachment within the jackets than the actual design of the spoiler. The zipper receiver within my two jackets is attached via elastic strip. I believe this is so that the jacket has some give to it should you decide to zip it to some pants for a 2-piece suit. As a result this elastic strip causes the spoiler to hang too low. Another side effect of the low hanging spoiler is that the ends can poke out from underneath my jacket and the wind will actually cause the spoiler to flip up and render it useless. As mentioned by another reviewer, the zipper lengths do not line up. July 21, 2015
Finally My gift to society is ordering one of these and covering the hairy mushroom top that is my midsection. I ordered the M, L, and XL to try and fit into my Large 2014 Alpinestars Gunner jacket and the Large ended being perfect. All three are identical except for the zipper length. I took some measurements with a cloth tape measure from the middle of zipper handle (the part you pull) to the end of the little metal tang on the end. Medium - 27 Inches Large - 28 Inches XL - Nearly 29 Inches November 6, 2014
Great if your A* jacket is short. I bought this jacket spoiler because my torso is long and my jacket is always above my belt. The "spoiler" zips in easily and helps keep the jacket in place. Even with a backpack on, the material of the spoiler makes it kind of grip you and not ride up. Looks pretty normal when installed on the jacket. I got an XL spoiler and it fits well in a 58 Euro AlpineStars GP-R jacket. April 26, 2014
Good accesory Perfect accessory for the jacket to cover the lower back and also for person who can see your butt crack. recommended that if using medium jacket buy a size large. October 7, 2013
Good cosmetic add on. Great idea to lengthen the back of a riding jacket. However, the sizing is off. I wear a size medium jacket so you would think a size medium spoiler will fit perfectly. Not so, package label on the medium says it fits size small jackets. Zipper was an inch too short for my jacket. Strange that Alpinestars would do that on the sizing. Luckily my mom is a seamstress. She fixed it so now the zipper lines up perfectly. March 22, 2013
Alpinestar Jacket Spoiler Great addition, prevents air from flowing where it shouldn't be in the cold and adds "style" if you could say to any jacket... Very comportable doesn't get in the way on or off the bike, easily attached and removed. November 22, 2012
Should have gotten sooner! Had no idea these existed. Wished for one as long as I've ridden my CBR...if you don't mind showing your butt crack when you ride or you don't ride when its colder, this isn't for you...BUT if you don't like showing your regrettable lower back tattoo to the world when you ride or ride when it is colder...or just want to look plain cool...get this. When not riding..sitting or walking around, you cannot tell you have it on as it doesn't interfere at all. I switch it back and forth between my Astars leather and textile jackets. Friggn AWESOME!!!

Taylor B: Go with the same size as your jacket. I have a large a stars viper and a large spoiler. The zipper is a tad long on the jacket but it all works out. Large is what a stars suggested when I called them to ask. Mar 20, 2014

Ulf R: I have a US size 12 (European size 48) Alpinestars leather jacket and bought a spoiler size large. It works but is actually 1/2-1" too large so a size medium would probably have been better. Mar 21, 2014

Philip S: Order 1 size larger than your jacket. If you have a Small jacket, order a Medium spoiler. Don't know why they don't make the medium fit the medium, but that's the way it works. Mar 20, 2014

Ulf R: After reading the advice I chose size large for my medium size EUR 48 jacket. That was wrong. The zipper on the spoiler is an inch too long. It works OK but is obviously not perfect. I would choose a large spoiler for a large jcket a medium spoiler for a medium jacket etc Nov 17, 2014

Taylor B: Large. It won't fill up the entire zipper. You'll have about an inch left on the jacket but it's ok it fits well Nov 16, 2014
