THE FABRIC
Why merino wool
Merino wool moves sweat away from your skin as vapour and lets it evaporate from the fabric, so you stay dry and comfortable whether you are hiking, commuting or skiing.
Merino fibres naturally resist the bacteria that cause odour, so you can wear a base layer for several days, on the trail or while travelling, and it still smells fresh.
Wool can absorb up to 30% of its weight in moisture without feeling wet. In damp British weather it keeps insulating where cotton and polyester leave you cold.
Merino absorbs UV radiation: our lightweight layers offer UPF 25 and the midweight and heavyweight options UPF 50+, handy on long days in the hills.
Merino wool is naturally hard to ignite and self-extinguishes without melting onto the skin, unlike synthetic base layers.
Merino is a natural, renewable and biodegradable fibre. Sheep grow a new fleece every year, and a worn-out merino garment breaks down instead of shedding plastic microfibres.
FAQ
Merino socks, beanies & accessories: FAQ
What is this walking & hiking socks best for?
It is made for walking boots, hillwalking and everyday wear. Like all our merino, it stays warm when damp and resists odour, so you can wear it for longer between washes.
Are merino wool socks good for walking boots?
Yes. Merino hiking socks cushion your feet, wick sweat and keep insulating when damp, which helps reduce the moisture that leads to blisters on long days in boots.
Do merino socks keep feet warm in winter?
Yes. Merino traps warm air even when your feet sweat, so it keeps toes warmer than cotton socks in cold, wet conditions.
What size merino socks should I buy?
Choose your size from the size guide. If you are between two sizes, pick the larger size for boots and the smaller one for trainers.
What is a merino neck gaiter used for?
A neck gaiter (snood) can be worn as a neck warmer, face cover, headband or beanie, so it replaces several accessories for cycling, skiing, running and walking the dog on cold mornings.
How do I wash merino socks, beanies and boxers?
Turn them inside out and machine wash at 30°C on a wool or delicate cycle, then air-dry. Avoid tumble drying and fabric softener to keep them soft and in shape.
