Huck yourself with reckless abandon. Don't worry, the Alpinestars MTB Bionic Jacket has your back. It also has your forearms, elbows, shoulders, and chest. Tough polyurethane and impact foam protects your vitals while all-over stretch mesh construction keeps you from burning up. The Bionic is also compatible with neck protectors, so the only traction that will be on your mind is what you're getting from your tires.
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.
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.
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.
