Size guide

Our pieces follow standard US men's sizing, from S to XXL. The short answer: take the size you usually wear.

Which size to take

Order your usual size. For most men, in most of our pieces, that's the right call.
Between two sizes? Size up for an easier fit, particularly if you wear a shirt or a layer underneath.
On every product page, Find my fit next to the sizes starts from the size you usually wear, and Fit and sizing gives the model's height and the size worn in the photos.

Body measurements

These are body measurements, not garment measurements. Measure over a thin shirt and compare.

Size	Chest	Waist	Hips
S	35 to 37.5 in 89 to 95 cm	29 to 31 in 73 to 79 cm	35 to 37.5 in 89 to 95 cm
M	37.5 to 41 in 95 to 104 cm	31 to 35 in 79 to 89 cm	37.5 to 41 in 95 to 104 cm
L	41 to 44 in 104 to 112 cm	35 to 37 in 89 to 94 cm	41 to 44.5 in 104 to 113 cm
XL	44 to 47.5 in 112 to 121 cm	37 to 41 in 94 to 104 cm	44.5 to 47.5 in 113 to 121 cm
XXL	47.5 to 50 in 121 to 127 cm	41 to 42.5 in 104 to 108 cm	47.5 to 50 in 121 to 127 cm

How to measure

Chest: measure around the fullest part of your chest, just under the arms, with the tape level across your back.
Waist: measure around your natural waistline, where you would normally wear your trousers.
Hips: stand with your feet together and measure around the widest part of your hips and seat.

Keep the tape snug, not tight. And if your measurements point to two different sizes, go by your usual size and how you like a piece to fit.

CasmerinoAustralian Merino Wool^®

Our Australian merino has fine 17.5 micron fibers that feel soft against bare skin. The Woolmark^® label vouches for its fiber content, color fastness and shape retention.
With NATIVA^™, every bale is traceable to its farm of origin, and every farm is mulesing-free.
The Responsible Wool Standard (RWS) sets clear requirements for how the sheep are cared for and how their grazing land is managed.
Each piece carries the OEKO-TEX^® STANDARD 100 label: every thread, button and trim is tested for harmful substances.

Good to know.

Quick answers before you order.

Ask us anything else

It has a classic fit. Take your usual size, and if you are between two, size up for an easier fit.

Yes. Tap Find my fit next to the sizes. It asks a few short questions, starting with the size you usually wear, and suggests a size for this piece.

The Fit and sizing section above gives the model's height and the size worn in the photos, so you can compare it with your own build.

Not with the right care. Heat and a tumble dryer are what shrink wool, so wash it cool, by hand or on a wool cycle, and dry it flat.

Send it back within 30 days and the return costs you nothing. Then order the size you want.

100% merino wool, in a 14-gauge fine knit. Every detail is listed under Fabric and details above.

Itch comes from coarse fibers. Merino is much finer than ordinary wool, so it feels soft on bare skin.

Any natural knit can pill a little where it rubs, under the arms or along the sides, mostly in the first weeks. A sweater comb lifts it off in a minute.

Less often than you think: merino resists odor, so airing it between wears is often enough. When it does need a wash, go cool, by hand or on a wool cycle, and lay it flat to dry in the shade. No bleach, no tumble dryer.

Fold it rather than hang it, so the shoulders keep their shape. Store it clean in a drawer or a breathable bag, with a little cedar if moths are a worry.

Great for cold walks

I wear this on cold morning walks with my dog and it holds up great. The collar lies flat and doesnt flap around in the wind which I like. Buttons are small but smooth, never catch on anything. Ribbed cuffs keep the cold out at the wrists better than I expected for something this light. Black color looks great layered under my jacket. Been out in it plenty of mornings now, no complaints.

Comfy all day long

Put this on in the morning and kinda forget I'm wearing it by lunch, that's how comfy it is. No itch or weird tightness anywhere. Feels right all day whether I'm at a desk or out running errands. Got the ivory and it still looks fresh after wearing it a bunch already. One of my favorite pieces for anything that isn't super casual.

Fits close not tight

Fit through the chest and shoulders is close without feeling tight when I move around outside. Only small thing is the sleeves run a touch long for my arms, had to push them up a bit on hikes.

Washes well

Got the black in a medium after already owning one in khaki, washes just as well and holds up fine, no issues so far. Only thing is i wish it came with a few more button options but thats minor.

Good for the office

Wore this to the office a few times instead of my usual department store shirts. So much more comfortable. Ivory looks clean and a bit dressy without trying too hard.
