Fabric weight guide
Which merino weight is right for you?
GSM is grams per square metre — how much fabric there is, not a warmth rating. Every weight is the same soft 17.5-micron Australian merino: it wicks sweat before it turns cold, insulates when it is cold and ventilates when it is warm. Lighter fabric breathes and dries faster; heavier fabric holds more heat when you stop moving. Choose by season and by how hard you will be working.
Warm & hot weather · 60°F+ / 15°C+ — and high effort in any season
Best for: summer hiking, running, cycling, hot-climate travel, everyday tees and office wear; the next-to-skin layer under a 250 when you work hard in winter
Pick this if: you want a shirt that stays fresh for days, dries in an hour and keeps you cooler than cotton in the heat — or you simply run hot
Think twice if: you will mostly be standing still in the cold; on its own a lightweight layer has little insulation to offer
Shop 165 GSM →Cool to mild · 40–65°F / 5–18°C
Best for: spring and autumn as a standalone top, summer evenings, cool-morning hikes and commutes; winter as a base under a mid-layer
Pick this if: you want one merino layer that covers most of the year, or you are unsure between light and mid — this is where most people should start
Think twice if: you run cold and your winter is genuinely cold: go straight to 250
Shop 190 GSM →Cold · 20–45°F / −7–7°C — the classic winter base layer
Best for: skiing and snowboarding, winter hiking, cold-weather work, frosty autumn mornings; top-and-bottom sets so your legs are not the weak link
Pick this if: you run cold in fall, want the classic winter base layer, or spend active days below freezing under a shell
Think twice if: you overheat easily on hard uphill efforts — a 165 or 190 underneath, 250 over it, is the better system
Shop 250 GSM →Deep cold · below 25°F / −4°C — especially when you stop moving
Best for: ice fishing, hunting stands, camp at altitude, winter mornings spent waiting rather than walking, a house that never quite gets warm
Pick this if: warmth matters more than breathability, you are chronically cold, or your winter involves long spells standing still outdoors
Think twice if: you will be working hard — it is too warm for a sweaty climb, which is exactly the point
Shop 320 GSM →A base layer works by sitting close to the skin, where it can move moisture — loose is not more comfortable, just slower. Between sizes? Size down for a next-to-skin layer under a shell, size up to wear it on its own or over another layer. Merino stretches with wear and springs back after a wash. Heavier weight is not itchier: itch comes from coarse fibre, and every weight here is the same superfine merino.

Description
Men's Merino Wool Polo
Designed for men who demand comfort and refinement, this Burgundy Merino Wool Polo combines cutting-edge textile performance with timeless style. The secret lies in Merino wool’s natural thermoregulation, which adapts to your body temperature — keeping you cozy in winter and cool in summer.
The fabric’s breathability and moisture management ensure lasting dryness, while odor-resistant fibres keep you feeling fresh no matter how busy your day gets. Soft to the touch, lightweight, and naturally elastic, it fits effortlessly while retaining its shape.
Enhanced with UV protection and antistatic stability, this polo transitions seamlessly from the office to the outdoors. And because it’s made from renewable fibres, it’s as gentle on the planet as it is on your skin.
Care
Turn inside out. Machine wash cold on a gentle cycle with a wool-safe detergent. Do not bleach. Lay flat or hang to dry.

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
Men's merino T-shirts, polos & shirts: FAQ
What is this 180gsm polo shirt best for?
It is a lightweight 180gsm merino layer, best for work, golf and travel. Compare every weight in our merino weight guide.
Is a merino T-shirt good in hot weather?
Yes. Lightweight merino breathes, moves sweat away and keeps you cooler and drier than cotton, and it offers natural UV protection, which makes it ideal for summer, travel and warm-weather hiking.
Does a merino T-shirt smell after exercise?
Much less than cotton or polyester. Merino resists odour-causing bacteria, so you can wear the same T-shirt for several days of travel or back-to-back training sessions.
How do merino T-shirts and polos fit?
They have a relaxed everyday fit and are true to size. If you prefer a closer athletic fit, size down. See the size guide.
Can I wear a merino polo or shirt to work?
Yes. The polos and button-up shirts look like smart everyday shirts, stay fresh through long days and resist wrinkles in a suitcase, which is why they are popular for business travel.
How do I stop a merino T-shirt getting holes?
Wash it inside out at 30°C on a gentle cycle, dry it flat, and avoid rough rucksack straps and velcro rubbing the same spot. Store it clean and folded to keep moths away.
Absolutely love this shirt. The fit and feel is perfect and the colour is gorgeous.
