Fit
iJ.bonKa is the first Assos insulator Jacket available in two specific pattern designs:

• mod. Cento - tailored to fit the Slim Pro-cyclist build
• mod. Mille - tailored to suit the more robust, performance regularFit athletic body type

Assos Layering System (ALS) Tips
ASSOS offers 7 climaRange specific interactive body insulators. Preferably, use the iJ.bonKa with mod.interactive.6. However, the ALS is a guideline. Using a lighter or heavier next-to-skin interactive body insulator, you can perfectly calibrate to your needs and extend climaRange use. When riding conditions are below 0°C (32°F), try wearing two layers: interactive fall.4 combined with interactive winter.6 and the bonKa over it. It works! The iJ.bonKa has been designed to function perfectly within the system: Combine it with the ASSOS LL.716 tights for maximum performance.

Technological Engineering
The iJ.bonKa represents Assos core competence at their finest: custom, exclusive boutique fabrics combined with legendary pre-shaped, riding position specific pattern design know-how. It is engineered using the ASSOS science of body-mapping pattern design. Meaning, performance specific textiles are applied on various parts of the body to ensure perfect temperature control in cold, winter riding conditions. iJ.bonKa protects and insulates your body it doesn't suffocate it!

Construction

• The iJ.bonKa features 32 Pattern pieces, 6 different textiles and 13 components.
• The chest and upper arm sections are a labour-intensive double-layer construction, a combination of stratagonUltra airBlock textile outside and RXQ fabric inside. This produces a more effective insulation and a better contouring fit.
• The chest and elbow areas feature an additional, in-between wind protection layer.
• Inside the collar area, the iJ.bonKa features an additional, ergonomically shaped inner layer turtleneck construction that contours to your chest and collar perfectly. This enables you to work with the front main zipper as an additional ventilation device up hills, without decreasing chest and collar insulation.
• The rear panel features ASSOS RX textile for enhanced ventilation, allowing the iJ.bonKa to transport vapour effectively.
• An integrated rear stabilizer panel design enables the iJ.bonKa to click onto your body, reduce vertical stretch and keep loaded pockets in position with no sagging.
• The side panels and lower arms are made out of the new ASSOS airBlock membrane textile, stratagonMedium

Fabric Technology
The iJ.bonKa uses Stratagon Ultra, a new textile developed by Assos which is able to respond intelligently to changes in climatic conditions and body temperature.

The innovation lies in the garment engineering. Instead of applying a traditional membrane sandwich (textiles glued together), ASSOS opted for a newly developed “TwinDeckFoiling” technology solution. StratagonUltra is used as the outer layer and functions as a super light, super elastic shield, ensuring thermal response action, windproofing and water resistance. Underneath is a free moving RXQ inner layer insulator fabric. Its duty is to maintain a stable temperature by insulating and taking care of moisture management.

ASSOS technology “TwinDeckFoiling” is used on the front and upper arm panels, providing increased contouring, four-way stretch fit and accelerated moisture transfer properties. Although a more expensive assembly process, the advantages justify the cost.

Stratagon ultra is an ultrathin 3 layer laminated fabric construction. It features the latest in membrane technology: "flexible barrier function". When the temperature is low, the membrane reduces permeability, meaning the membrane "closes", which helps retain body heat.

As your temperature increases, the membrane opens to enhance the evaporation process, ensuring stabilization of your body temperature. The result is effective body temperature management. The advantage of the new Assos Stratagon generation of laminated fabrics is that they get the job done FASTER and feature lower volume to weight ratio than any other membrane textiles currently used in cycling apparel. Stratagon Ultra also has extreme elastic properties resulting in a garment that fits, insulates and follows your body better.
