Knitwear · the main line
Knitwear is the heart of the wardrobe. We match each knit to its band by gauge and weight: the finer the needle, the warmer the day.

Whole outfits, one click
Every band has two to four sets, built from the skin out. Pick one size and add the lot. There are fifteen in all.

Set of 4 £187
+ £4.95 UK delivery · £191.95 total
Each piece is added in the colour shown. For other colours or mixed sizes, open a piece and add it on its own.
Inside every hem sits a small woven label with one temperature range. It is the same on every colour of a piece and it never changes. Wear what matches the day, add the next band up when the wind picks up.
Ranges are a styling guide for everyday walking in light wind. Everyone runs a little warmer or colder, so treat them as a starting point, not a laboratory rating.
