Merino vs Cotton: What's the Difference?

It's one of the most common questions when people consider switching from cotton to merino wool: is it really worth the money? The answer depends on what you use your clothes for, and what you expect from them. Here's an honest comparison of the two materials, based on facts and our own experience working with both.

The short version

Merino wool outperforms cotton on almost every technical parameter: temperature regulation, odour resistance, moisture wicking and durability. Cotton wins on price and availability. If you want clothing that performs more and lasts longer, merino is the right choice. If budget is the primary factor, cotton is still fine for many situations.

Comparison: Merino wool vs Cotton

Property Merino wool Cotton
Temperature regulation Active — insulates in cold, cools in heat Passive — no thermoregulation
Odour resistance High — does not bind bacteria Low — smells quickly with sweat
Moisture wicking Absorbs up to 35% of its weight Absorbs moisture but retains it
Drying time Fast Slow
Durability High with proper care Moderate — loses shape over time
Sustainability Biodegradable, longer lifespan Biodegradable, but high water usage
Price Higher purchase price Lower purchase price

When is merino the right choice?

Merino wool makes the most sense in situations where clothing needs to perform:

  • Travel: A merino t-shirt can be worn for several days without washing, dries quickly and packs compactly. You can get through an entire weekend with one garment.
  • Sport and outdoor: Merino's moisture wicking and odour resistance make it superior for running, hiking, cycling and fitness. You stay dry and fresh, even during intense activity.
  • Everyday quality: If you prefer fewer, better things in your wardrobe, merino is the natural choice. One merino t-shirt can replace three cotton shirts in terms of function and durability.
  • Temperature changes: Merino adapts to your body and surroundings. Ideal for days when the weather changes, or when you move between indoors and outdoors.

When is cotton good enough?

Cotton is not a bad material. It's simply limited compared to merino. Cotton works fine in situations where:

  • You're mainly at home: For relaxing on the sofa or a quiet day at home, cotton is perfectly fine.
  • Minimal sweat production: If you don't sweat much in your daily life, you won't notice cotton's limitations as clearly.
  • Budget is decisive: Cotton t-shirts cost a fraction of merino. If price per piece matters more than price per wear, cotton is the obvious choice.

Our honest assessment

We make merino wool clothing, so we naturally have a bias. But we try to be honest: merino wins on performance, comfort and durability. Cotton wins on price. That's the simple truth.

Our mission at LOOW is to make merino more accessible. We design in Denmark, produce in Europe and sell directly, without costly intermediaries. That means you get merino quality at a price that's not far from premium cotton.

For most people, the best start is to replace one cotton shirt with a merino t-shirt and feel the difference yourself. Not because we say so, but because your body does.

Frequently asked questions

Is merino really better than cotton?

For most uses, yes. Merino regulates temperature, resists odour and wicks moisture better than cotton. The biggest practical advantage is that you wash far less often, saving time and reducing wear on the garment.

Can merino replace cotton entirely?

In principle, yes. Many of our customers have switched their entire t-shirt wardrobe to merino. It requires an upfront investment, but over time it's both cheaper and more practical.

Does merino itch like regular wool?

No. Modern merino wool uses ultra-fine fibres (under 17.5 micron) that are significantly softer than traditional wool. LOOW uses down to 15.5 micron fibres, that's softer than most cotton shirts.

What is the best merino t-shirt to start with?

We recommend our O-Neck 160 as the perfect starting point. It's versatile enough for everything from the office to the weekend and gives the best overview of merino's benefits. For summer, the O-Neck 135 is a great alternative.
