Moso bamboo · Phyllostachys edulis
Knowledge nugget
Moso reaches its full height in three to five years and is cut without uprooting. The grove keeps on standing. The next shoot is already on its way up.
Kairo · Bamboo edition
Walk the
bamboo way.
Bamboo viscose, knit close to the foot. Cooler than cotton, naturally odor‑resistant, and grown without pesticides on land that won't take a crop.

The fibre
Bamboo behaves
differently than cotton.
Where cotton flattens against the skin, bamboo viscose stays hollow. Every fibre carries a column of air. That's why the same sock can feel cooler in summer, warmer in winter, and softer all year.
Four properties to feel
Four properties to trust
01Moisture wicking
Bamboo's hollow micro‑channels pull sweat off the skin and out through the knit. The foot stays dry across a long day on its feet.
02Odor resistant
A natural compound in the fibre suppresses the bacteria that turn sweat into smell. Wear them twice between washes without noticing.
03Ultra soft
The fibre's rounded cross‑section has no sharp edges. The result feels closer to brushed silk than to combed cotton against bare skin.
04All‑day comfort
Cushioned under the heel and ball of the foot, with a hand‑linked seamless toe. Sixteen hours in and you forget they are there.
Grown clean
No pesticides. No irrigation. No replanting.
Breathable knit
A loose gauge for constant micro‑airflow.
Reinforced
Doubled at the heel and toe, the first places to wear.
Quietly made
Knit in small batches. Inspected by hand.
The proof
Bamboo socks vs. the cotton pair in your drawer.
Kairo bamboo
Standard cotton
Moisture
Kairo bamboo
Wicks 30%+ more sweat
0Hollow micro-channels in bamboo fibre move sweat off skin to the outer surface, where it evaporates.
Standard cotton
Soaks and holds it
0Cotton absorbs up to 25× its weight in water and stays heavy. Foot stays damp.
Odor
Kairo bamboo
Naturally antibacterial
0Bamboo's own antimicrobial properties slow the bacteria that cause odor. No added silver, no synthetic finish.
Standard cotton
Builds smell fast
0Damp cotton is a culture medium for odor-producing bacteria. Day-two socks tell the story.
Friction & blisters
Kairo bamboo
Round, silk-smooth filament
0Continuous round-section fibre slides past skin instead of catching it. Less rub, fewer hot spots.
Standard cotton
Short rough staples
0Spun from short fibres with rough ends. The classic culprit behind blisters on long days.
Water to grow
Kairo bamboo
≈ 1 L per kg of fibre
0Bamboo grows on rainfall alone in poor soils, including reclaimed slopes that won't take other crops.
Standard cotton
≈ 10,000 L per kg
0Conventional cotton is one of the thirstiest crops in commercial agriculture.
Chemicals
Kairo bamboo
Grown without pesticides
0No pesticides, no fertiliser, no irrigation. We use closed-loop processing for the viscose stage.
Standard cotton
Heavy spray + sulfur dye
0Roughly 16% of the world's insecticides go into cotton. Sulfur dyeing is standard for dark socks.

The Journey
From grove
to foot.
Four steps from a living grove to a pair you can put on. Each one stays close to the plant.
- IIStep 02
Transformation
Pulp from stalk
Knowledge nugget
Stalks are chipped, softened and reduced to a clean cellulose pulp. The same regenerated-cellulose family as viscose and modal (ISO 2076).
- IIIStep 03
Yarn
Wet-spun filament
Knowledge nugget
The pulp is drawn into long, round-section filaments, washed, and twisted into a calm, even yarn that takes colour quietly.
- IVStep 04
Knit
Close to the foot
Knowledge nugget
Knit in the round, linked at the toe by hand, then checked pair by pair and folded into a recycled-kraft sleeve.
