BUYING BASE LAYERS
Base layers are as much about summer riding as they are autumn/winter…
The quick and easy route to more comfortable riding.
WHAT IS A BASE LAYER AND HOW DO I WEAR ONE?
Base layers are the foundation of a layering system and exist to keep you comfortably warm, cool and dry. They wick sweat away from skin which helps riders stay cooler and drier, and can act as a trap for a layer of air that’ll keep you warmer. Base layers are a gateway to a much more comfortable riding experience.
SUMMER V WINTER BASE LAYERS
The primary function of summer base layers is to keep you cool by wicking sweat away from the skin, and heat along with it. Winter base layers perform that same function to a lesser degree, but also retain a layer of air that acts as a very effective insulator.
‘Many manufacturers offer base layers nowadays, but… some are better than others’
MATERIALS AND THE BRANDS TO LOOK FOR
Synthetic fibres such as polyester and polypropylene formed into materials that incorporate tiny air gaps are prime base layer territory. Cotton, while a good insulator, can absorb a lot of moisture which means you’ll get cold and uncomfortable in double quick time. Coolmax is another material that’s effective at wicking. Outlast was originally designed for NASA and has phase-changing molecules which can store heat for release when it gets cold, or absorb excess heat when it is warm, for release later. Merino wool is a natural material that has the same effect as the winter-biased fibres, its fine fibrous makeup offering a high insulation-to-weight ratio, as well as anti-odour properties. It’s also good for those with sensitive skin.
WHAT ARE THE BEST LAYERS?
Many manufacturers offer base layers nowadays, but as it is with all other kinds of kit some are better than others. The best place to start your research is by considering the various material options (see above) and the kind of riding you do, ie are you a year round rider, or summer only?
WHAT DOES COMPRESSION FIT OFFER?
Traditionally worn by athletes, or passengers on long-haul flights, compression fit clothing offers a range of benefits. Most notably for bikers it improves circulation when you’re not moving too much, such as long motorway stints. It can also reduce the risk of any undesirable chafing.
GET THE RIGHT FIT
The best thing you can do is try potentials on, with the rest of your usual gear, and then sit on your bike for a few minutes. Technical base layers tend to feel much tighter than normal clothing, but there shouldn’t be any rubbing or uncomfortable pressure. At Bike Stop we have a bikeshaped frame in the shop, so you don’t have to keep running out to your bike. Otherwise we have an online store (bikestop. co.uk) and offer free returns if you find something doesn’t quite fit when you try it on.
MOTORCYCLE BASE LAYERS V THERMALS
For starters there are base layers that include armour, which is handy if you’re a motorcycle rider. Knox offer several alternatives here and some of these layers are actually okay to use without anything on top of them. Layers without armour have a fit that is designed to be okay for those who are sat still for a long time (like compression wear) but still need the insulation and wicking properties of a good piece of thermal underwear. Basic longjohns and thermals have a habit of going baggy in places that are tight when stood up, but loose when crouched over a bike.
