Which size should I choose?

Choose your usual size and check it against the size guide on the product page. Most customers find it true to size; a few find the sleeves a little long, while others find the fit a little snug.

Is it warm enough for winter?

It’s a warm but lightweight t-shirt, not a thick layer: most customers find it warm, though a few expected more warmth. In very cold weather, add another layer or a jacket.

Does it wick away sweat effectively?

Yes. It’s fully breathable and the fabric dries quickly, helping prevent a chill when you stop moving.

Does it retain odours?

The POLYGIENE® StayFresh treatment helps limit odours and bacteria during activity. It doesn’t replace washing: wash the t-shirt after an outing where you’ve sweated heavily.

How should I wear this t-shirt?

Wear it next to your skin as a base layer, or on its own in cool weather. For intense activity in cold weather, add a jacket or softshell over it. The thumb loops keep your wrists warm.

How is it different from a standard long-sleeved t-shirt?

It’s made from polyester and elastane, which wick away sweat. A cotton t-shirt holds onto moisture and can leave you cold during breaks. It also has SMARTWARM® fibres for warmth, a thumb loop and a zipped back pocket.

How should I wash this t-shirt?

Wash at 30 °C maximum, without fabric softener: it clogs the fabric’s micropores and slows the release of sweat. Air-dry it and avoid tumble-drying.

Is it made from merino wool or synthetic fibres?

It is synthetic: 90% polyester and 10% elastane, in a 180 g/m² fabric. It contains no merino wool.

What are the delivery times for this product?

All orders placed by midnight are prepared the next day. In France, orders placed before 1 pm (excluding weekends) with Chronopost 24h are dispatched the same day. Delivery then depends on the carrier and takes 1 to 4 days in France. Delivery times for Europe and the rest of the world vary by destination.

Can I return the item if the size doesn't fit?

Yes, absolutely. You have 30 days to return it and get a refund or an exchange. Return shipping is free. The item must be new, unworn, unwashed, and have its original tag.

In summary This content is written by AI

Customers love its second-skin comfort: soft, stretchy and free from chafing, it is easy to forget during activity. Many praise its breathability and quick drying, with welcome warmth without bulky fabric, although one customer found it less warm than advertised. Lightweight and easy to care for, it suits running, climbing and outings in cool weather, even when packed in a rucksack. It does run slightly large, however: if you are between sizes, choose the smaller one.

The second time I have bought one of these. The original is still my favourite trail running top and sometimes baselayer. It's extremely soft and just the right weight. Ideal for ultras in Kerry.

The fit is slim, but the fabric is stretchy and soft to the touch, making it very comfortable. Even putting your thumb in the sleeve hole doesn't force the stretch. My chest is 103 cm, my shoulders are 46 cm, and I'm 173 cm tall, so I'd buy it again in a size M.
