Important considerations winter cycling base layer choice:

Long vs. short sleeves

Long-sleeve base layers are generally preferred in winter since they are warmer and provide more coverage, while short-sleeve versions are better for summer or spring months. However, if the winter is relatively mild, you can get away with some short-sleeve base layers.


The two most popular base layer fabrics are merino wool and synthetic. Merino wool is a natural fabric that is very warm, comfortable, feels pleasant against the skin, and has natural antibacterial properties (it does not need to be washed after every ride, which can be crucial on a multi-day adventure). The synthetic fabric is usually cheaper, more durable, lighter, and dries faster than merino wool. Generally, the higher the price, the better fabric quality you get (both merino wool & synthetic). We also discuss the differences between these fabrics in the frequently asked questions section in case you need help choosing the right fabric for your needs.


The best base layers are pretty close-fitting but should not cause any discomfort. Ideally, look for a pleasant, second-skin fit and feel.

Additional considerations

Some base layers offer neck warmers that can be used as a face covering. Also, it’s better to find a base layer with minimum seams & zippers. Last, but not least, think about your riding conditions (mostly temperature) when shopping for winter cycling base layers.

Frequently asked questions:
1. What is the difference between merino wool fabric and synthetic?

Merino wool fabric is a natural material that is super soft against the skin and has the amazing ability to generate a tiny bit of heat when wet. This is why it is such a warm fabric and a preferred choice by many people. It also does not smell after repeated usage (natural antibacterial properties) and prevents rashes. The fabric works by absorbing a bit of water inside microscopic tubes, and then the rest is wicked away. However, merino wool takes longer to dry than synthetic fabrics, making it less suitable for high-intensity rides when you are likely to sweat a lot.


Synthetic fibers generally don’t absorb water and work purely on evaporation compared to merino wool. This is why base layers made of synthetic have fantastic wicking properties and dry so fast. Synthetic is generally lighter and tighter fitting making it a preferred fabric choice for athletics and higher-intensity cycling workouts.

2. Should I get merino wool or a synthetic base layer?

This depends on the conditions you plan to use the base layer in. For example, synthetics are generally better for athletics and high-intensity sports. So if you go out to train and exercise, go with synthetic fabrics. It is also lighter and fits closer to the skin.


However, if you are commuting (not sweating a lot) and need to stay dry and get straight to work without smelling bad, then merino wool is your best friend. Also, you are backpacking or going for a multi-day adventure without the possibility of jumping into a shower; then, again, merino wool is your choice.

3. What is the best base layer for winter?

Again, this depends on the weather conditions and what you plan to use it for. A thicker long sleeve thermal base layer is generally better in freezing temperatures to keep you warmer. 


A long sleeve synthetic base layer is preferred by athletes who cycle for sport and exercise. This type of fabric is also great at wicking away sweat and is very light. 


For commuting and recreational cycling, merino wool is better as you don’t need to wash it after each use as this type of fabric has natural antibacterial properties. 


So, to sum up, the best base layer for winter really depends on the conditions you are cycling in, intensity level, and how long you want to use the base layer before washing. Our list of best winter base layers in this article includes impressive options to choose from, so we are confident you can find something that suits your needs.

4. Are base layers good for cycling?

Base layers are definitely a must for cycling. If you are cycling in cold weather, then a winter base layer helps to keep your body warm even when it is wet (sweating). This is achieved by wicking the sweat away from the skin and keeping it dry and thus warm. In winter, base layers work best if combined with a good outer shell, for example, a windproof or waterproof jacket or a jersey.


In summer, base layers are also super helpful as they help keep you comfortable and cool by wicking sweat away from your skin and preventing chafing from bib straps or cycling jerseys. Most cyclists have several base layers in their wardrobes for various weather conditions and seasons.

5. Is a merino wool base layer good?

It depends on the brand and overall fabric quality, but in general, yes, merino wool is a very good base layer fabric. It absorbs the sweat from your body and keeps you warm even when the fabric is getting wet. It is also very comfortable, feels great against the skin, prevents itching, and does not need to be washed after every use. 


However, some cheaper brands might not be as comfortable, and the fabric might even irritate your skin. So if you are looking to buy a merino wool base layer, make sure to do your research and be wary of the cheap price tag.

6. How tight should a base layer be?

It depends on the type of cycling you do. For example, if you are doing high-intensity training, you would want a base layer that is tighter fitting as it will be better at wicking the body sweat. However, a looser fit is more comfortable for commuting or leisure cycling. So, it really comes down to your needs and the type of cyclist you are.


However, generally speaking, the fit should be tight but comfortable at the same time. So, it is best to try on a few different base layers before purchasing to see which fits you the best. If you are ordering online, get a few options, try them on, and send back the ones you dislike.

7. Do you wear anything under a base layer?

No. A base layer is meant to be worn directly against the skin. Typically, you will wear a jersey or a jacket on top. Layering is key to dressing for the weather.

8. What is a wicking base layer?

A wicking base layer is the one that helps to move sweat away from your skin and keeps you dry. Today, most base layers used for sports have some wicking properties. As a result, such base layers prevent you from getting cold in winter and overheating in summer.
