Why merino wool?

There's a reason wool has kept people warm for thousands of years, and a reason we keep using it in a number of our product ranges. Merino is one of those rare materials that does more than its job description, and once you've ridden in it, it's hard to go back.

Here's what makes it special, and a few answers to the questions people always ask before they try it.

It keeps you warm when it's cold, and cool when it's hot

This is the part that sounds too good to be true, so it's worth explaining.

Each merino fibre is naturally crimped, which means it traps tiny pockets of air close to your skin. That trapped air is what keeps you warm on a frosty morning. But the same fibre is also brilliant at moving moisture away as vapour, which is what keeps you cool when you're working hard and the sun's out.

Most fabrics are good at one or the other. Merino manages both, which is why it's the layer that can handle whatever the ride throws at it.

It manages sweat without the cold, clammy feeling

You know the feeling when you've pushed hard up a climb, you're soaked through, then you crest the top, start the descent, and suddenly you're freezing in a wet jersey.

Merino handles this differently. Rather than just sitting on the surface, it absorbs moisture into the fibre itself and releases it gradually as vapour. The result is that it feels dry against the skin even when it's working hard, so you don't get that sudden chill the moment you stop. For the start-stop rhythm of real riding, climbs, descents, traffic lights and coffee, that makes a genuine difference to comfort.

You can wear it for days

This is the one people really love. Merino is naturally odour resistant, because it resists the bacteria that cause smell in the first place. In practice that means you can wear it across several rides between washes and it still feels fresh.

If you commute, tour, bikepack, or travel light for a weekend away, this is the benefit that shines brightest. One jersey for multiple days.

"But isn't wool itchy?"

Fair question, but it depends entirely on the wool.

Itch comes down to how fine the fibres are, measured in microns. Coarse wool, the kind in an old jumper, sits at the scratchy end. Merino is far finer. Anything under around 19.5 micron is considered soft enough to wear next to the skin, and good cycling merino sits comfortably below that. At that fineness the fibres flex against your skin rather than prickling it, so there's no scratch, even on a bare-armed summer ride.

So if itchy wool put you off years ago, the merino in modern kit is a different thing entirely.

"Why blend it? Isn't pure wool better?"

You'd think so, but pure merino has real weaknesses on the bike. On its own it's slow to dry, it can stretch out of shape, and it wears through faster than you'd like for something you're paying good money for.

So blending isn't cutting corners, it's the opposite. Pairing merino with fibres like recycled polyester, lyocell or a touch of stretch gives you the best of both: the natural warmth, breathability and odour resistance of wool, plus faster drying, a better fit that holds its shape, lower weight and a garment that lasts season after season. You get the feel of merino against your skin and the performance of modern fabric everywhere it counts.

How to choose the right weight

Not all merino clothing is built for the same conditions, and weight is the thing to look at. As a rough guide:

• Lightweight open-knit and mesh fabrics are year-round and warm-weather must-haves, built for airflow on hot days and as a breathable base layer underneath everything else.
• Mid-weight knits hit the sweet spot for spring and autumn riding, where you want a bit of insulation without overheating.
• Heavier long-sleeve fabrics come into their own for cold starts and transitional seasons, holding warmth while still letting your body breathe.

Pick by the conditions you ride in most, and a single merino layer will cover a surprisingly wide range of weather.

A material that's kinder, and lasts longer

Two last things worth knowing.

First, the wool itself. The merino we use is non-mulesed, which matters if you care where your clothes come from and how the animals behind it are treated.

Second, because merino needs washing far less often than synthetics, it uses less water and less energy over its life, and a well-made merino garment will keep going for years. Add in the fact that it looks and feels good enough to wear off the bike, and you've got a layer that earns its keep well beyond the ride.

Give it one good ride and you'll understand why we keep coming back to it.
