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.

Quick answers before you order.

Ask us anything else

It has a slim 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. This one is 17.5 microns.

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.

Runs small

Washed it once and it held up fine but the fit through the chest felt tight for a medium, had to size up next time, otherwise the fabric itself seems fine.

Didn't expect this

Figured it would be another so-so sweater but it's really warm under a coat and doesn't feel bulky at all.

Great for work

been wearing this to the office like three times a week now, fits slim but not tight and goes under my blazer no problem. soft as hell too, no itch at all which was my main worry. the roll neck stays up all day which is clutch. ngl this might be my favorite thing i bought all year. already thinking about grabbing another color for rotation.
