Merino wool is a natural fibre that offers many benefits for outdoor enthusiasts. It is soft, breathable, moisture-wicking, temperature-regulating, odour-resistant and durable. Merino wool base layers are the foundation of a good layering system, which helps you stay comfortable and perform well in different weather conditions and activities.
In this blog post, we will explain how to layer your merino wool base layers for optimal comfort and performance, whether you are hiking, skiing, cycling or just enjoying the outdoors.
What is a layering system?
A layering system is a way of dressing in multiple layers of clothing that work together to keep you warm, dry and comfortable. The basic principle of a layering system is to add or remove layers depending on the temperature, weather and activity level.
A typical layering system consists of three main layers:
- Base layer: The layer that is in direct contact with your skin. It should be lightweight and breathable, and wick away sweat from your body. This layer helps you regulate your body temperature and prevent overheating or chilling.
- Mid layer: The layer that provides insulation and warmth. It should be thicker and warmer than the base layer, but still breathable and moisture-wicking. This layer traps air and creates a buffer between your body and the cold environment.
- Outer layer: The layer that protects you from wind, rain and snow. It should be waterproof, windproof and durable, but still allow some ventilation. This layer shields you from the elements and prevents heat loss.
Why choose merino wool base layers?
Merino wool base layers are ideal for any outdoor activity because they offer many advantages over synthetic or cotton base layers. Some of the benefits of merino wool base layers are:
- Softness: Merino wool is very fine and soft, unlike traditional wool that can be coarse and itchy. Merino wool feels smooth and comfortable against your skin, and does not cause any irritation or chafing.
- Breathability: Merino wool is highly breathable, meaning it allows air to circulate through the fabric and regulate your body temperature. Merino wool also absorbs moisture vapour from your skin and releases it into the air, keeping you dry and fresh.
- Moisture-wicking: Merino wool is excellent at wicking away sweat from your body, preventing it from accumulating on your skin or clothing. This helps you avoid feeling clammy or sticky, and reduces the risk of bacterial growth and odour.
- Temperature-regulation: Merino wool is a natural thermoregulator, meaning it adapts to your body temperature and the environment. Merino wool can keep you warm when it is cold, and cool when it is hot, by creating a microclimate around your body.
- Odour-resistance: Merino wool has natural antibacterial properties that inhibit the growth of odour-causing bacteria on the fabric. This means you can wear merino wool base layers for longer without washing them, saving water and energy.
- Durability: Merino wool is strong and resilient, and can withstand repeated wear and washes without losing its shape or quality. Merino wool also resists pilling, fading and shrinking, making it a long-lasting investment.
How to choose merino wool base layers?
When choosing merino wool base layers, there are some factors to consider such as weight, fit, style and care.
-
Weight: Merino wool base layers come in different weights or thicknesses, depending on how warm or cool you want them to be. The weight is usually measured in grams per square metre (gsm) or microns (µm). The lower the number, the lighter and thinner the fabric. For example:
- Lightweight: 150-200 gsm or 17-18.5 µm. Ideal for warm or mild weather, or high-intensity activities such as running or cycling.
- Midweight: 200-260 gsm or 18.5-20 µm. Ideal for cool or cold weather, or moderate-intensity activities such as hiking or skiing.
- Heavyweight: 260-320 gsm or 20-24 µm. Ideal for very cold weather, or low-intensity activities such as camping or lounging.
-
Fit: Merino wool base layers should fit snugly but not too tightly on your body, allowing some room for movement and air circulation. They should also cover your torso and limbs adequately, without being too long or short. A good fit will ensure optimal comfort and performance of your base layers.
-
Style: Merino wool base layers come in various styles such as tops, bottoms, underwear, socks, hats, gloves and more. You can choose the style that suits your preference and activity. For example:
- Tops: You can choose from short-sleeved, long-sleeved, crew-neck, v-neck, zip-neck or hoodie styles. Zip-neck or hoodie styles are good for adjusting your ventilation and warmth, while crew-neck or v-neck styles are good for layering under other garments.
- Bottoms: You can choose from leggings, tights, shorts or pants styles. Leggings or tights are good for fitting under other pants or trousers, while shorts or pants are good for wearing alone or over other base layers.
- Underwear: You can choose from briefs, boxers, thongs, bras or camisoles styles. Underwear should be comfortable and supportive, and match your top and bottom base layers.
- Socks: You can choose from ankle, crew, knee-high or over-the-calf styles. Socks should be cushioned and seamless, and fit well with your shoes or boots.
- Hats: You can choose from beanies, caps, balaclavas or headbands styles. Hats should cover your ears and forehead, and fit snugly on your head.
- Gloves: You can choose from fingerless, full-fingered, mittens or liners styles. Gloves should protect your fingers and palms, and fit well with your outer layer gloves.
-
Care: Merino wool base layers are easy to care for and maintain. They do not need to be washed as often as synthetic or cotton base layers, as they are naturally odour-resistant and stain-resistant. However, when you do wash them, you should follow these tips:
- Wash them in cold or lukewarm water, either by hand or in a gentle machine cycle.
- Use a mild detergent that is suitable for wool or delicate fabrics. Do not use bleach or fabric softener.
- Dry them flat or on a line in the shade. Do not tumble dry or iron them.
- Store them in a cool and dry place, away from direct sunlight or heat sources. Fold them neatly or roll them up to avoid creases.
