Assos IJ Bonka 6 Winter Jacket (Cento Fit)
Assos IJ bonka 6 Winter Jacket (Cento fit)
Eight years it has taken for Assos to replace their winter jacket, but this Assos IJ bonka 6 Winter Jacket (Cento fit) has been well worth the wait. This windproof and water resistant jacket has been insulated in key areas without increasing volume, weight or bulk to create a supreme performer.
Key areas for protecting have been the chest and upper arms. Here Assos have incorporated their latest technology - TwinDeckFoiling. This combines layers of strataGonUltra airBlock fabric for the outer layer and RXQ material inside for the ultimate insulation, flexibility and breathability. These materials also add to the luxury feel you would expect from Assos. Temperature control at the front is regulated by a full length zipper.
Additional protection has been incorporated into the chest and elbows to seal up those vulnerable areas. Alternatively, the collar makes use of an ergonomically shaped inner layer turtleneck design.
A rear constructed in RX fabric means no warmth is lost, but maintains breathability to allow you to achieve the optimal body temperature for performance. Finally, the integration of an Assos rear stabiliser panel design means the bonka fits perfectly when cycling.
Quality comes at a price, but with Assos you know it will more than pay off in the short and long term.
- Assos have designed this to work in the cycling position. Therefore, they state that it should feel "all wrong" when worn standing, but perfectly snug when cycling.
- This is the Cento fit version - tailored for a slim competition fit. See Mille for a more relaxed fit.
