Hemp

Hemp is a tough bast fiber with a good environmental story and a reputation for feeling rough. Here is what the research supports, what it doesn’t, and how to read a hemp label.

At a glance

Origin: Plant fiber from the stalk of industrial hemp (Cannabis sativa L.), a bast fiber like flax.

How processed: Natural, but processing varies a lot: long fiber is retted and spun like linen; “cottonised” hemp is cut and softened to spin like cotton; some extraction methods use enzymes or chemicals. Any plant dissolved into viscose, as with “bamboo” rayon, becomes regenerated cellulose, not a natural fiber.12

What it is and how it’s made

Hemp textile fiber comes from the stalk of industrial hemp, Cannabis sativa L.1

The fiber is freed by dew retting, water retting, enzymatic or chemical retting, steam explosion or mechanical decortication, and the method changes fiber quality.13

Long hemp fiber can be spun on linen systems. Shorter “cottonised” hemp runs on cotton machinery, which is cheaper, but the yarn is less even and loses some of hemp’s strength, cool touch and pilling resistance.1

How it wears

DurabilityLong hemp fibers have high tenacity, comparable to flax.1
SoftnessLignin in hemp fiber makes it stiff, which is one reason hemp can feel coarse. Cottonised hemp and cotton blends feel softer.1
MoistureHemp fibers absorb moisture readily, like other cellulose fibers.1
WrinklingFabrics made from cottonised hemp can resist wrinkling better than long-fiber hemp.1
Breathability and warmthStudies of clothing and body temperature find construction matters more than fiber, and we found none on hemp specifically.45
OdorHemp is often sold as antibacterial or odor-resistant. A review mentions antibacterial and UV-blocking activity, but we found no wear trials on hemp garments, so we don’t repeat the claim.1
ColorIn one lab comparison, hemp fabric took dye least well of the cellulose fabrics tested, so expect softer, less saturated colors.6
CareCare depends on the blend: hemp with lyocell and elastane behaves differently from hemp with cotton, so follow the label.78

Environmental notes

  • Hemp grows tall and dense with thick leaves, shading out weeds, so farmers can use fewer herbicides.1
  • A 2005 study of UK hemp found it rain-fed, needing about 2,100–3,400 liters of water per kg of usable fiber, against about 9,800 liters for the irrigated cotton the UK imports.9
  • Dew retting and closed-loop water retting are the lowest-impact extraction routes; chemical retting is not environmentally neutral, and water retting needs wastewater treatment.13

Counterpoints and caveats

  • It can feel coarse, and the softer cottonised versions give up some of what makes hemp hemp.1
  • Many “hemp” garments are blends. Toad&Co’s Taj Hemp Shirt, for example, is 54% hemp, 44% Tencel lyocell and 2% elastane.7
  • Plant names get attached to regenerated rayon: US regulators fined Kohl’s and Walmart for selling rayon as “bamboo.” A “hemp” label on a viscose fabric deserves the same suspicion.2
  • The water comparison is from 2005, covers UK growing only, and was commissioned by a group developing hemp textiles.9

Buying tips

  • Check the percentage. Hemp with organic cotton is all natural; hemp with lyocell, viscose, polyester or elastane isn’t.87
  • Expect a break-in period with long-fiber hemp; choose cottonised hemp or a cotton blend if softness matters most.1
  • If a plant-named fabric is listed as viscose, rayon or modal, it’s regenerated cellulose, whatever plant it came from; regulators have fined retailers over “bamboo” rayon.2

Common garments

  • Button-up and camp shirts
  • Tees (often hemp and cotton)
  • Chore jackets and workwear
  • Shorts and trousers

Short answers

Is hemp better for the environment than cotton?

On water and herbicides it looks better: a UK study found rain-fed hemp needed roughly a quarter to a third of the water of irrigated cotton per kg of fiber, and dense hemp crops suppress weeds.91

Counterpoint: The study is from 2005 and was commissioned by a hemp textile developer; processing choices can erase the gains.

Why does hemp clothing feel rough?

Hemp fiber contains lignin, which makes it stiff. Cottonised hemp and blends with cotton are softer.1

Counterpoint: Cottonising also gives up some strength and pilling resistance.

Is hemp fabric antibacterial?

A review mentions antibacterial and UV-blocking activity in hemp fiber, but we found no wear trials on hemp garments.1

Counterpoint: Treat odor claims on hemp clothing as unproven.
