  • dhb Aeron Merino SS Base Layer (M_37.5)

    Take the natural insulation and softness of merino wool and pair it with 37.5™ Technology to maintain the ideal body temperature and you have the incredible dhb Aeron Merino SS Base Layer (M_37.5).

    The key to cycling comfort is to achieve a stable body temperature - if you're too warm you sweat too much which then leads to feeling a chill when you reduce the intensity - not enough insulation and you'll instantly feel below par and motivation wanes. The Aeron Merino SS Base Layer (M_37.5) is a base layer to get you in that sweet spot of perfect body temperature, not too hot and not too cold. 

     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.

    Marvellous Merino

    So what does Merino wool bring to this base layer party? Well, Merino Wool is incredibly soft against the skin for one, creating a base layer you'll love to slip on. It's also a natural insulator, even when wet and it lets your skin breathe too. Lastly, it has resistance to bacteria build-up which lessens odours, meaning you can wear day after day and still feel fresh, plus extend the time between washes.
