Description
When it comes to staying warm in all conditions, the Assos Layering System (ALS) is of the highest possible calibre, and the Assos iJ haBu5 Jacket fits perfectly into this system. This windproof jacket has been insulated in key areas without increasing volume, weight or bulk to create a supreme performer.
The stratagonUltra airBlock fabric insulation on the front and upper arm panels prevent chilly air from entering but does not compromise flexibility or breathability and maintains that luxury feel you expect from Assos. Temperature regulation on the front is complimented by a full length zip, with reflective cover for added visibility.
Insulation is also added to the side and lower arms where the new, light and warm RXQ material has been used. This compliments the thermal properties of the stratagonLight material, but maintains breathability to allow you to achieve the optimal body temperature for performance. Finally, the new high collar adds the final touch, as it is a high performing, windproof material.
Although this is a stunning jacket, practicality has not been lost. The three rear pockets allow you to keep ride essentials near to hand. Most usefully, the two side pockets are zippered so that items can be held more securely.
Please note: 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.
