Base Layer 4 Plus Long Sleeve Black
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.

adding some winter gear and started with the base layer. q never lets me down; collar sits up higher than most, love it. seamlessness makes it that much more comfortable. looking forward to the colder days to put it to the test but i have no doubt it will perform at the highest level as all t q products do.

Q36.5 is for me synonym for quality! The Base Layer 4 Long Sleeve is a must to have in cold winterday ridings. The Base adapt immediately on the shape of your body. Its warm and smooth. Give it a try!

L’évacuation de la transpiration est très réussie. Cet article est adapté à une activité dynamique soutenue. Il est très extensible et reste donc très près du corps.

Love it. Nice and snug for cold weather riding. I tend to wear it at 5°c and lower. With the BL3 from 5-10°C in winter conditions.

This base layer does exactly what it says in the description. Combined with the winter adventure jacket you get a temperature management system that really works. I rode in 35 degree weather the other day and was warm with no heat build up. Rode with the same set up in 45 degree rain with the same results. Excellent product. I have written maybe one or two reviews in my life, which should tell you something.
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.
