The collar holds
Every cheap polo I owned curled at the collar by the third wash. This one has been through six and still lies flat. EU 50 fits like EU 50.

Essential Knitted Crewneck T-Shirt | Silk, Cotton and Lyocell | Castielli
A short sleeve crewneck knitted from a blend of mulberry silk, cotton and lyocell, finished with a subtly ribbed collar, hem and cuffs. The black shade is the quiet workhorse of a summer wardrobe: soft, breathable and impossible to overdress or underdress.
Why you'll reach for it
- Mulberry silk blend: silk adds a dry, cool touch and a low sheen that separates this tee from basic cotton.
- Lyocell content: wicks moisture and drapes cleanly, so the shirt hangs straight instead of clinging.
- Ribbed edges: collar and cuffs keep their line wash after wash.
- Standard fit: cut straight through the body with sleeves that end mid bicep, easy to wear alone or under a light jacket.
Fit and fabric
Standard fit, true to size, in EU sizes XS to 2XL. The knit has natural give, so it moves with you without bagging out at the waist. At 30 degrees it wears noticeably cooler than a jersey cotton tee of the same weight.
Care
- Machine wash cold in a mesh bag on a gentle cycle.
- Dry flat away from direct heat to protect the silk fibers.
Shipping and guarantee
- Free worldwide tracked shipping, 7 to 12 business days, taxes and duties included
- Free size exchange if the size is not right

The Fabric
Natural fibres, chosen by season
Linen for the hot months. Extra-fine merino and cashmere for the cold ones. Every piece starts from the fibre that behaves best in its season, cut with room to move and finished to hold its line.
The Craft
Details you notice on the tenth wear
Reinforced seams and hems finished straight. Ribbing that springs back after a full day. The kind of detail you check after a season of wear, and it is still there.

A week in Lisbon on two pieces
Same shirt and trousers for seven days at 34 degrees. They came back looking like they had not left the wardrobe.
Fits like the chart says
I measured my chest first for once and took the L the guide pointed at. It landed exactly right, shoulders included.
Wore it three days running
Two flights and a conference. No creases that a hanger did not fix overnight.
Dressed up or down
Under a jacket for a dinner in Porto, on its own the next morning. Nobody looked twice either time.
The knit holds its shape
Sat on it, packed it, pulled it out of a bag after four hours. No bagging at the elbows.
Second one in a month
Bought the navy, wore it twice in a week, ordered the sand before the second wash.
The ribbing at the cuff holds
My last polo had sleeves that flared out by week two. This one has not moved.
Size up if you are broad
Beautiful merino, warm without the bulk. I sit between L and XL and the guide told me to take the XL. I did not listen, which is on me and not on them.
Runs a touch warm
Lovely knit, but at 30 degrees I reach for the linen instead. Perfect for spring and autumn.
Held it against a 300 euro sweater
Same hand, same weight. With my eyes shut I could not tell them apart, and with them open it took a while.
Ordered a second before the first arrived
Saw enough in the photos and the sizing chart. Both fit the same, which matters.
As described
Colour matches the photos. Heavier than expected, which I like.
No logo anywhere
The reason I bought it. Nothing on the chest, nothing on the sleeve.
Wish the navy came in 2XL
The fit and fabric are right, the size I want sells out. Took the XL and it works, just.
Held up to a washing machine mistake
Went in at 40 by accident. Came out the same size, which I did not deserve.
No pilling after a month
My last knit at this price was covered in bobbles by week three. Nothing here yet.
Delivery took ten days
Longer than I hoped but exactly what the page said. Product is worth the wait.
Packs flat
Rolled two of these into a carry on for four days and never touched an iron.
The buttons sit flat
No gaping at the placket when it is open, which is where cheaper polos give themselves away.
The neck does not stretch
Pulled over the head twice a week for a month and it still sits close.
Wears well under a blazer
Thin enough at the shoulder to layer without bulking.
Better than the brand I left
Was paying nearly double elsewhere for the same weight of cotton.
Third order this year
Two polos and the trousers. Nothing has needed an exchange.
Colour slightly lighter than shown
The sand reads a touch paler in daylight than in the listing. Still good, just not identical.
More colours, please
The four on offer are all good. I would buy two more if the range went wider.
Survived a toddler
Which is the only durability test that has ever mattered in my house.
Fabric does not go shiny
My old ones picked up a sheen after a season of washes. Not here yet.
Sleeve length is right
Most short sleeves either cut at the bicep or hang to the elbow. This one lands where it should.
Would like a tall option
At 194cm the body is a fraction short when I raise my arms. The XL solves it mostly.
