Nine Lives Geometric Cat Hoodie

A geometric cat hoodie and a gift for cat dads and cat lovers: twenty-seven rings that grow from a circle into a sitting cat, printed large on the back of heavy 350 gsm oversized fleece, in black or Eden Green.

A circle, a cat, and the twenty-five steps between them.

Twenty-seven lines from one equation. The innermost is a plain circle. Each ring outward is allowed a little more of the cat — ears rising, cheeks widening — and turned a little less, until the outermost line arrives as the whole animal, sitting still. Nine lives, three times over.

The design

Sage, forest-green and rust rings across the back, with every ninth line drawn in cream so the lives can be counted. Above it the Nekomori wordmark and Field Equations / No.02 Nine Lives; below, 猫森 and the equation itself: r_k(θ) = s_k[(1 − t_k) + t_k·r(θ − φ_k)]. A small version of the drawing sits on the left chest.

The fit

Oversized, with a dropped shoulder and a roomy body. Take your usual size for the intended slouch, or size down for a closer fit. Heavy fleece, soft on the inside.

The blank

• 350 g/m² (10.3 oz) fleece
• 42% cotton, 53% polyester, 5% other fibres
• Drop shoulder, oversized cut, kangaroo pocket
• Sizes S–2XL
• Printed with DTF (direct-to-film) transfer

Giving it as a gift

A cat dad gift that doesn't say “cat dad” on it. The nine-lives line drawing reads as graphic design from across the room and as a cat up close, which suits anyone who loves cats, math or clean modern art, and the heavy fleece makes it a proper winter hoodie.

• Sizing for someone else: It's cut oversized, so their usual size gives the intended slouch; one size down gives a closer fit. Sizes S–2XL. If it doesn't fit, it can come back within 30 days of delivery, unworn, with free return shipping.
• Ordering for Christmas or a birthday: every piece is printed after it is ordered, so count back about three weeks and order before then. The dated delivery estimate under the buy button is the one to go by, and checkout offers express shipping on most garments if you are cutting it close.

Field Equations is Nekomori's series of cats drawn by mathematics instead of by hand: each design is a single equation, rendered, then left alone.

Printed for your order — nothing is held in stock. Artwork original to Nekomori, generated from the equation printed beneath it.
