Base layers are the base of any layering system - they are designed to sit next to the skin and wick moisture away from your body; they do this by absorbing moisture (sweat) from the surface of your skin, then allowing it to evaporate away.


By wicking sweat away from the body, a base layer keeps you dry, comfortable, and chill free. Thermal base layers can also help to keep you warm by trapping an insulating layer of warm air around the skin.

Base layers can be made of several materials: namely synthetics (Polyester or Polypropelene) or Merino wool.

Cycling base layers also come in a huge variety of styles. From long-sleeved, with high collars for the cooler weather, to mesh sleeveless garments for the hot days.

In this Wiggle guide, we look at what you should consider when you are buying a base layer, including the fit, the materials, and the season that you are buying for.


Cold-weather cycling base layers

Important factors to consider when buying a base layer for winter use:

  1. Material: you want a fabric that will provide warmth and insulation.
  2. Fit: just like a summer base layer, a winter layer also needs to be close fitting; to ensure you're trapping a layer of insulating air between body and fabric.
  3. Cut: base layers for cold weather can be short sleeve or long sleeve - personal preference comes in here, but also how adaptable you require your base layer to be.

Base layer materials for cold weather

Base layers are often made from synthetic materials that have been engineered to keep you warm and dry quickly.

Another great material for winter base layers is merino wool. Merino sheep have adapted to extreme conditions in their native country Australia. Thanks to their highly specialised wool, they thrive in the hot summers and harsh winters. The same properties that help keep merino sheep happy make merino wool perfect for sportswear. Durable, soft, thermal and moisture-wicking, it's an increasingly popular choice for base layers.


Cold weather base layer fit

Like summer base layers, it is vital that cold weather base layers fit close to your body. Luckily, both synthetic materials and Merino wool have great stretch properties.

Check the unique size guide on all base layer product pages, for a tailored fit.


Cold weather base layer cut

You may want to wear your base layer underneath a protective short-sleeved jersey, with arm warmers; in this case, you'll need a short sleeve winter base layer.

However, if you're wearing your winter base layer with a jacket or long sleeve jersey, then we highly recommend a long sleeve base layer.

Longer sleeves keep warmer blood flowing to your forearms, and then onto your hands; helping to keep this vital extremity warm and protected from the chill.

Summer cycling base layers

The most important factors to consider for your summer cycling base layers are:

  1. Material: you want a fabric that will wick moisture away from your skin, leaving you cool and dry.
  2. Fit: you want a summer base layer to be close fitting, so it doesn't clump underneath tight summer riding kit, and so it sits close to your skin.
  3. Cut: summer base layers come in short-sleeved and sleeveless options. What will be best for you, depends on the riding conditions and your other riding kit.

Summer base layer materials

Summer base layers are normally made of synthetic materials because of their excellent stretch properties. Along with providing a good fit, they are resistant to shrinking with continued use and highly effective at wicking away moisture.

Look out for fast dry fabrics such as CoolMax, CoolMesh, ThermoCool and DriFit; these will ensure sweat is quickly moved away from the body, keeping you cool and comfortable.

Many modern polyester fabrics also use odour reducing technology such as Microban and Polygiene. These anti-microbial finishes stop odour building up in the base layer, even with heavy perspiration, making them more pleasant when in use for long days in the saddle.


Summer base layer fit

The great stretch properties of modern synthetic materials mean base layers can fit like a second skin. Indeed it's important they do to provide the best moisture management.

Use our detailed size guides on each base layer product page, to ensure you get the best fit.

Sleeveless or short-sleeved? Summer base layers could be either.

Which one you choose depends largely on personal preference. A vest-style base layer will typically be cooler.

Wiggle tip: 

To make the most of your technical cycle clothing, you really need a base layer for each season. This will maximise warmth in the winter months and excess manage moisture in the summer. Having a good base layer can significantly improve your riding comfort and enjoyment in all seasons.

The fabric you opt for will depend on your budget and what you intend to use the product for. Merino wool is normally more expensive than polyester due to the expense of sourcing the material. However, it is worth spending more if you use the layer frequently or for longer rides.

Ensure you get a base layer that fits you well. Base layers are designed to be a second skin, so close-fitting profiles are vital. Sizes vary between manufacturers so check the size guide on individual products.
