Killer. Gorgeous. Tough.

Love my AStars Bionic Jacket! I wear a 42R jacket and all HnR had was XL but I got it anyway. It's a little loose in the shoulders, but with the wide kidney/rib protector strap it doesn't move around. The arms fit like a glove and the elbow pads don't move like some I've tried. Wish I could have gotten a large, but I'm pretty happy with this one.

I am 5'10" with a 44" chest and a 31" waist...

I am 5'10" with a 44" chest and a 31" waist and weigh 175lbs. Would the XL be too big. The Sizing Chart says 44" is for XL. But one of the reviews said a guy 6'5" 230lbs fit good. Xl & XXL are the only ones left.

I'm 5'10" and wear a 42R jacket. XL is slightly loose in the shoulders but fits really well overall.

Bionic Jacket

I'm a big guy (6'5 230) who is not very good at biking. This means I fall often and fall hard. After a broken collar bone suffered at a local resort, I decided it was worth the investment in body armor. The XL fit great and was surprisingly comfortable. It only took a few runs for it to pay for itself in a lack of trips to the ER as I softly bounced off the hard ground. The armor is a little more bulky then I'd like, and you have to wear it on the outside of clothing (unless you buy a shirt a couple sizes up but I think that might look even funnier) but you wont get this kind of protection without some bulk. Overall I'm very happy with my purchase. If you want great protection and you're okay with a little bulk, this is your jacket.

Very comfortable: top-notch materials and design

I'd highly recommend this piece of upper body armor. It's very comfortable and contours well with the body. Once it's on, you will sink right into the molded cups in the shoulders and elbows, it ain't going anywhere. The back plate is also very comfortable, you hardly notice you have it on. I also like the kidney belt, it velcros at the front and there are adjustments on the side as well, to really cinch yourself up. This is my first product from Alpinstars, but I'm very impressed with the quality, design, and materials.

Alpinestars MTB Bionic Jacket

Great Fit, High quality materials were used. Make sure to order a size smaller than you would normally wear for this is supposed to be snug and will mold to your body upon break in. H&R shipping was super fast and you cannot beat the price! Works well with the AStars BNS.

will this Jacket work with the alpinestars...

will this Jacket work with the alpinestars Bionic Neck Support SB or Carbon?

OK, so i guess i am going to answer my own question! This suit ROCKS! The Moto GP technology AStars put into this totally cut out all the bulk from the previous years Bionic Jacket. Fits like a fricken glove and looks sick to boot! i totally went for the sleaveles Jersey to show off the shoulder caps and sure enough wadded it up on Gypsy up at Northstar; looks even better when its dirty! So i must say this jacket in conjunction with the Bionic Neck Support are a winning combo, the neck brace matches up perfect. make sure you order the jacket to fit snug for it stretches upon break in.
