Assos iJ.Bonka.6 Cento Profblack Jacket (Limited Edition)


Free UK Delivery on orders over £100

Nowhere is the Assos "Sponsor Yourself" philosophy more prominent than in their ProfBlack range. Stylish, understated, timeless cycle clothing that's designed to perform.

This latest version of their brilliant Bonka jacket was a natural addition to the range.

It's their top of the range winter jacket, designed to cope with the coldest of conditions, but in true Assos fashion they've achieved a remarkable amount of insulation without adding bulk.

The Bonka is a core part of their range that has evolved over a number of years to attain iconic status, and when you wear one you'll soon see why. Like any ultimate product it doesn't come cheap, but we've yet to find a more effective winter warmer for cycling use.

Like all Assos garments it's designed with a cycling fit, and is tailored to feel most natural when in a 'cycling crouch'. When on the bike their attention to detail becomes apparent in how it simply "gets out of the way" - this is a far cry from bulky and restrictive winter jackets of the past, you'll only know it's there from the protection it provides.

Size Guide:

Assos clothing is cut anatomically to fit perfectly without restricting movement when in the riding position. Bibs might pull when standing upright - this is normal.

Assos tend to be a particularly slim fit - most people find they need to go up a size from their equivalent in other brands.

Measure around the widest part of your chest, just under the arms.
