The Feel

NATURALLY SOFT.
SCIENTIFICALLY
PROVEN.

Pineapple leaf fibre isn't just sustainable. It's a superior textile. Rich in cellulose (70–80%), PALF is naturally soft with a silk-like sheen. Lightweight, highly breathable, and resistant to shrinkage.

Piña cloth, woven from pineapple fibre, was worn by Filipino aristocracy in the 1800s as a symbol of wealth. We go further: 20% PALF in every single shirt.

The Science

WHY THE PINEAPPLE
IS A MASTERPIECE
OF NATURE.

Every pineapple carries a hidden mathematical code. The same principle that defines beauty in art, architecture, and the human body. Encoded in a tropical fruit.

Fibonacci spirals on pineapple

8 spirals left, 13 spirals right. Both Fibonacci numbers.

5 ∕ 3

Our Ratio. Our Identity.

5 and 3 are consecutive Fibonacci numbers. Their ratio, 1.667, approaches the golden ratio φ 1.618. The mathematical foundation of bromlain.

8 + 13

The Pineapple's Hidden Geometry

Count the scales on any pineapple: 8 spirals one way, 13 the other. The pineapple carries our fibre and our philosophy.

φ

The Golden Ratio

1.618033. Found in the Parthenon, in da Vinci's Vitruvian Man, in the spiral of a galaxy. And in every pineapple.

The Origin

FROM HARVEST WASTE
TO PREMIUM FABRIC.

Pineapples are cultivated across tropical regions worldwide. Each plant produces a single fruit and dozens of long, fibrous leaves. After harvest, these leaves are usually discarded. Millions of tonnes, every year.

Those leaves contain one of nature's finest raw materials: PALF, Pineapple Leaf Fibre. We blend 20% of this fibre with cotton. Naturally soft, highly breathable, silk-like lustre. Sustainable by nature, not by label.

bromelain, the enzyme inside the pineapple that softens fibres naturally during textile processing. It's in our name because it's the science behind the feel.

GOOD TO KNOW.

PALF stands for Pineapple Leaf Fibre. It is extracted from the long leaves of the pineapple plant. Rich in cellulose (70–80%), the fibre is naturally soft, lightweight, and features a silk-like sheen. The leaves are an agricultural byproduct. No additional land, water, or resources are required.
Bromelain is a proteolytic enzyme complex found in pineapples. In medicine: anti-inflammatory and wound-healing. In cosmetics: skin firmness and teeth whitening. In cancer research: tumour growth inhibition. In food: natural protein tenderiser. In textiles, our field: bio-polishing, fibre softening, dye uptake without harsh chemicals.
5 and 3 are consecutive Fibonacci numbers. Their ratio (1.667) approaches the golden ratio φ 1.618. The pineapple's scales form spirals of 8 and 13, also Fibonacci. 5∕3 connects our brand, our material, and the mathematics of nature.
For every 5 shirts sold, we plant 3 pineapple plants on a partner farm. The ratio 5:3 is the Fibonacci sequence that runs through everything we do. The plants produce fruit, the leaves feed back into future fabric production. A cycle that starts with a shirt.
Wash at maximum 40°C. Iron on low heat. Wash with similar colours. Do not bleach. PALF is naturally resistant to shrinkage.
The first collection, 2,350 pieces in three colours, will be announced to the Inner Circle before public launch.
