Is merino wool breathable
12 August 2024
Merino wool is famously breathable, lightweight and helps air to circulate, to keep you warm in the winter and cool in the summer. As well as being breathable, merino is soft and resilient, providing temperature regulation and effective moisture management. It's also naturally odour-resistant, making it ideal for wearing all year round.
Breathable fabrics have a certain structure which encourages airflow, as well as managing and absorbing moisture, to help regulate temperature whilst keeping you dry. As a natural fabric, merino wool offers excellent breathability, unlike many synthetic materials. Cotton and bamboo can also offer breathability, but merino has some additional benefits for high performance activewear, base layer and summer or winter clothing which we’ll look at below. In this article we’ll also answer key questions such as: is merino wool breathable, is merino wool breathable in hot weather, and is cotton or merino wool more breathable?
How does merino wool stay breathable
The naturally porous structure of merino wool is what makes it highly breathable, as the delicate fibres trap air inside the layers to help regulate temperature by insulating you against cold and heat - known as thermoregulation. Merino wool fabric is also highly absorbent, and can manage moisture by absorbing sweat and releasing it into the air to keep you comfortable. Merino wool also stays warm when wet, so it won’t make you feel cold like cotton and other fabrics can, even if you sweat a large amount or get caught in the rain. An added benefit of merino is that it’s naturally odour resistant too, and offers next-to-skin softness for all seasons.

Is cotton or merino wool more breathable
Are you wondering: is merino wool breathable in relation to cotton? They're both natural, resilient and breathable fabrics, and both have unique abilities which can offer different pros and cons when it comes to climates and conditions. In general, merino wool is considered the most versatile, as it can adapt to varying climates. It’s still lightweight and soft against skin but can be worn in both summer or winter, keeping you warm or cool depending on the weather. It’s also highly adaptable if the conditions change, and dries much faster than cotton, plus it’s considered stronger and more resilient.
When it comes to merino wool vs cotton, cotton is frequently the fabric of choice for very hot and dry conditions, and can also feel soft against your skin, but without the same moisture management capabilities it takes a lot longer to dry when it gets wet. It can also make you feel cold when wet. If the conditions turn cooler, cotton does not offer the same warmth as merino wool, as it doesn’t have the same insulating abilities, making its use more limited as a clothing material.
Why merino wool stays fresh
Merino wool’s natural odour resistance helps you stay fresh, even during intensive physical activity, which adds to its breathability skills. Rather than trap sweat, like some synthetic fabrics can, merino wool works hard to absorb these and release them, so you feel dry and comfortable. This also helps to reduce the growth of bacteria, which is what causes odours as you exercise.
Some people are surprised to hear that merino wool is an ideal fabric for summer. It’s very different to traditional wool, offering superior softness and a lightweight structure, without the scratchy feeling that other wool can have. Being comfortable to wear and offering exceptional performance, breathability is just one of many merino wool benefits.
How merino wool supports multi-day wear
When it comes to odour resistance and breathability, merino wool is a great choice for a range of indoor and outdoor activities. From underwear to outer layers, merino is resilient and adaptable enough to be worn all year round - whether you’re skiing, hiking, camping or simply relaxing. Try merino wool for outdoor activities, as well as gym clothing, socks and accessories, fleeces and jumpers or even super-soft and machine washable children’s wear for every day.
When it comes to wool, the source is important when looking at breathability and versatility. You may wonder: is wool breathable when it comes from traditional sheep? The answer is that traditional wool is still breathable, but merino wool has the edge thanks to its fine fibres and lightweight structure. Synthetic fabrics often trap odours and heat, reducing breathability.
Conclusion
Merino wool’s key benefits include its breathability, moisture management abilities and thermoregulating properties. It’s also naturally odour resistant, to keep you feeling fresh and dry, no matter what the conditions. So, is merino wool breathable enough to wear in the summer as well as winter? Absolutely! From freezing winters to warm climates, high performance merino wool is perfect for everyday wear as well as all sorts of outdoor activities.
