Base Layer 4 Plus Long Sleeve Navy Blue
The first and most striking characteristic of the Q36.5Base Layer 4 is its extraordinary softness and elasticity that allow the garment to stretch perfectly to the contours of your body for that invisible, next-to-body feeling. Combining this with our signature advanced body mapping, which uses multiple integrated structures and densities to accommodate the different sweat zones of the body, and a 100% seamless construction with an unhemmed finish, gives you a garment that is both high performing and practically indestructible even after years of use.

Technical Features
For premium protection in deep winter riding, the Q36.5 Base Layer 4 offers the supreme combination of essential moisture management and body heat retention. Our warp knitting seamless technology enhances comfort levels while the inclusion of intelligent materials ensure that this Base Layer promotes proper thermoregulation in the most difficult climatic environments even on intense rides.
The Emana® yarn is an organic ceramic polyamide yarn, which enhances micro circulation and oxygenation during physical activity allowing for a better thermoregulation and moisture exchange rate. To increase thermal capabilities while maintaining a low volume we have introduced the Hollow Fiber which allows functional insulation and reduced water load thanks to the hollow core structure that traps warm air.
The Q36.5 Base Layer 4 has greater elasticity and lower resistance to movement in all directions due to the Karl Mayer Seamless knitting machine’s ability to eliminate seams from all parts of multiple tubes. The proprietary honeycomb pattern of the knit is used in various densities and is coupled with open-mesh sections mapping the thermal requirements and regional sweat rates of the body.

This is a really good base layer. Thick and warm, while still feeling light weight and comfortable. Not as comfortable as the lighter Base layer 2, but still good.

The Q36.5 Dottore Pro Bib Shorts are the world’s leading high performance woven bib shorts, using technologies pioneered by Q36.5, continuously refined over the last ten years. From the very first pedal stroke, riders will appreciate a feeling of superior muscular support, comfort, and on-the-bike stability. This unique feeling is achieved through the use of four different proprietary woven fabrics as well as our patented Q LAB Air Chamois, which provides total comfort and superior moisture management. The use of a high-density woven material with gradual compression along the leg panels in particular ensures a superior alignment of muscle fibers during the repetitive action of lengthening and contracting the legs, creating an important performance advantage over long distances.

Advanced Body Mapping
The Base Layer features different levels of breathability and varying densities resulting in an ultra-low volume garment for maximum performance and comfort. The back is thinner than front resulting in advanced moisture wicking according to sweat zones.
Creaseless Fit
Thanks to a true seamless tubular construction the Q36.5 base layer has an extraordinary elasticity and low resistance to movement, becoming an intelligent second skin, covering the full surface area of your body, greatly increasing its functionality in regulating your core body temperature. Seamless, unhemmed, construction also makes this base layer pratically indestructible even after years of use.
Temperature Management
The intelligent multi structure of the material actively keeps you warm by stimulating blood circulation of the upper skin layer while the hollow yarn retains generated body heat to keep you warm. Push-pull moisture management eliminates sweat build-up.
