The Assos iJ.bonkaCENTO Jacket highlights the commitment the Swiss apparel maker has to providing top notch racing apparel, even when the temperatures drop. It's similar to the bonkaMILLE in the evolution of the airJack, except the CENTO leaves room for much more than a tight base layer underneath. It uses Assos slimFit tailoring for the competition cycling body type. With a wind-proof front and sleeves and possessing a great close fit, this jacket is a windproof jacket where you need it to be and a jersey everywhere else. Assos stepped up their game again; they went back to the drawing board and came up with the iJ.bonkaCENTO Jacket, to stay one step ahead of competitors.
