Factors To Look For When Buying The Best Merino Wool Base Layer

As a customer, you should know exactly what to look for when shopping for Merino wool base layers. After all, it is essential to understand the very purpose of buying the base layer and what you expect from it.

1. Quality Of The Material

The first and foremost aspect to keep in mind when shopping for the best Merino wool base layers is the quality of the material.

As Merino wool fabrics can differ based on the diameter, density, and porosity of fibres, you can get different qualities in Merino base layers. The smaller the diameter of the Merino wool fibre is, the softer will be the fabric.

Base layers are usually made of Merino wool fibres with a diameter between 17 and 24 microns, and the density may range between 130g/m2 and 250 g/m2. Often, Merino wool fabrics carry blends of synthetic fibres to increase the lifespan.

2. Durability

Keep in mind that any garment made of pure Merino wool will not be as durable as synthetic materials. This is why many manufacturers prefer to use blends of Merino wool with synthetic materials.

While the higher content of synthetic fibres may increase the lifespan, they tend to overpower the natural properties of the Merino wool. So, look for the right balance of high performance and durability when shopping for Merino garments.

3. Warmth And Comfort

You are, of course, looking for the best Merino wool base layers for that warmth and comfort. Generally, the weight of Merino garments is measured in GSM or grams per square meter to give you an idea. 150 GSM ratings are considered optimal for warmer temperatures, while 250 GSM is ideal for the colder climates.

Merino base layers feel very comfortable, as they are made of ultra-fine soft and light fibres that have high breathability. Thus, when you wear these base layers, you feel light and enjoy all the freedom to move your body without any discomfort.

Moreover, Merino carries the property to absorb the moisture and keep your body odour-free and sweat free.

So, check out the quality and GSM ratings of the Merino base layers before buying them.

4. Kind Of Seams

Expert manufacturers use flatlock seams to avoid any rubbing or chafing that cause possible discomfort.

So, check out the seams of the base layer, and if they can be the cause of any discomfort. This is particularly important if you are used to wearing tight-fitting base layers. The best ones carry flatlock seams.

5. Right Fit

The base layer you pick should offer just the right fit and should not be loose or tight. The fit for the base layer influences the performance, and a lot relies on the kind of weather conditions around you.

For example, people living in warmer climates prefer slightly loose fit for better ventilation, while those in cold conditions prefer to buy slightly tight-fitting base layers for a snug and warm fit.

6. Price

The cost factor is often the key deciding factor when buying the best Merino wool base layers. Merino wool and material can be expensive, and it is not uncommon to see highly-priced Merino garments in the market. Some of those Merino shirts can easily cost more than $100, while Merino socks can cost about $20 to $30.

When you start shopping for Merino wool base layers, you will come across a wide range based on brand and quality.

As a general rule, the higher the purity and quality of Merino wool fibres, the more expensive the garment would be. 100% Merino base layers would cost more than synthetic blends of Merino.

3. How To Take Care Of Garments Made From Merino Wool?
