Two Tone Colour Block Joggers 'Katami'

Blue and cream colour-block joggers with a chain at the hip and a thigh pocket

Blue above, cream below, and a chain. These joggers are colour-blocked at the thigh, slate blue at the top and cream on the lower leg with a blue stripe down the side, with a flap pocket on the right thigh, a short chain hanging at the left hip, pale back pockets, toggles at the knee and a ribbed cuff. The blocks are sewn, not printed, so the seams show.

It is the pair in the collection for someone who wants colour and not a print, and the chain is the detail that people notice second and ask about first.

The name, Katami, is one side, the half, and the trousers are two of them.

The cut is a jogger: a soft waistband with a drawstring, room through the thigh, a taper to the knee and a ribbed cuff at the ankle that sits on the trainer. It is the shape Tokyo wears to the convenience store and to the club, and it does both. The cloth is a light woven polyester-cotton blend with a dry, matte hand, chosen because a street trouser must take a crease without keeping it, wash without shrinking and weigh nothing on a hot day, and a blend does all three. The chain is metal and clips off. The blocks are separate panels of cloth, seamed.

Wear them with a white tee and white trainers, as in the photograph, which is the outfit every pair in this collection was photographed in and the one they are all best in. A black tee in the evening, a haori or a sukajan over the top when it turns, and nothing else with a pattern below the waist.

They wash cold, inside out, and dry on a line; the cloth does not crease into a map and does not need an iron, which is the point of a trouser cut for a street rather than an office.

From across a street they are blue-and-cream joggers. From close the seams show where the blocks meet, the chain its links, the pocket its print, and the cuff its rib. They are the pair for a white trainer and a blue jacket.

The back pockets are pale, patched onto the blue seat, and the toggles at the knee cinch the lower leg if you want the cream narrow. The waist is a flat elastic under the drawstring.

Sizes run from S to 3XL. It is cut to Asian sizing and runs small, so take one size up from your usual. Between two sizes, take the larger.
