The humble base layer is a fundamental member of any cyclist’s wardrobe and we all wear them, but are we getting the most out of them?
There’s more to this commonplace garment than initially meets the eye, so here’s what you need to know.
Cycling Base layers: Fit
Like everything in road cycling, a performance base layer should sit close to the skin. Its tight fitting properties make it far more comfortable when your working hard and sweating lots. Should you have the misfortune of falling off, it plays a part in preventing road rash.
Cycling base layers tend to be technical, tight-fitting items of clothing
However, if you’re commuting or a more casual rider, you can probably get away with a looser fit.
A tight fit will also make the product more comfortable and less prone to rubbing or chafing as it should sit tight to the skin and not move.

Necklines are particular important, too. Some will have a low cut neck to avoid discomfort and rubbing. Some heavy-duty thermals will come a high neck, which will add warmth.
Looser fitting layers can be comfortable, though
Checking the length of both the arms and the torso is also important and a base layer should be generous in both areas. This should mean that your wrists are covered and there are no gaps between your base layer and your bib shorts.

Cycling base layers: Long sleeves, short sleeves… no sleeves?
This is a big question for base layer lovers and the answer is largely dictated by the season.
In the winter months, you’re definitely going to want to prioritise long sleeves, purely for the additional coverage that they offer.

If you like the added comfort offered by base layers then short sleeved, or even no sleeved options, are great for the warmer months. Plus they can be useful if the mornings are chilly.

Cycling base layers: Materials
This is one of the more important questions to ask when buying a base layer. The material will affect a products comfort, how much smells and, more importantly, how warm it will keep you.
Basically, there are two kinds of materials that a baselayer can be made off – either man made or natural.

If you’d rather go au natural then you’ll be looking to get a product made of Merino wool, primarily coming from New Zealand or Australia.
Merino’s fine weave can be stink free and very comfortable
Merino wool has heaps of great attributes, which makes it an awesome fabric for base layers. For starters, it’s largely stink-free, meaning you’ll get more rides out of it for each wash. This obviously has benefits if you’re riding lots, or more than once each day.
It’s also fast drying, which is great because unlike man made products, it doesn’t wick sweat away particularly well and can become very damp, very quickly. Happily, it’s a great insulator, though, even if it is wet.

Man-made materials are typically the opposite. They wick sweat away well, but tend to be smellier and need washing more.
Man-made synthetics are great but can get a little stinky
Both merino and man-made base layers have different grades of thickness so you can get the right one for you. If you tend to get very warm when riding then naturally makes sense to get a thinner layer and vice versa.
With so many options available, it makes sense have several layers than you can circulate, depending on the weather.
