Base Layer 4 Plus Long Sleeve Poppy Orange

Average rating of 4.9 out of 5 stars

(55)

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.

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.

The body of the pedal is made from forged 7057 aluminium and 54mm Q-factor with a total weight of 254 g (Shimano Dura Ace 252 g).The Unique Pro 4.0 shoe is the first and only shoe in the world to offer compatibility with SRM’s revolutionary new X-Power Direct road pedal system.SETUP GUIDE: When installing this pedal on your bike, please adjust the saddle height by lowering it 6mm compared to the height used with Shimano or Look pedals.

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.
