37.5™ Technology - Active Particle Performance
So why exactly 37.5? Well simply put 37.5°C is your ideal core body temperature while 37.5% is the optimum relative humidity in your micro-climate. 37.5™ technology actively works to maintain this optimum balance, so you perform better and in greater comfort no matter how high or low the intensity of your riding.
When you are in this ideal 37.5 zone, you'll be in your ideal performance zone. So how does it achieve this perfect balance? A layer of 37.5™ active particles have been added to this merino wool fabric, working hard to increase moisture transfer. The harder you work, the harder this fabric works to keep you in your perfect equilibrium.

Merino provides outstanding thermal regulation, odor resistance and breathability. Comfy next to the skin, this is the idea base layer for all day rides in changeable conditions.
