Hemp is one of the oldest cultivated fibers in human history, and one of the most misunderstood. Here's what actually makes it a stronger choice than cotton or synthetics — fiber by fiber.
| Hemp | Cotton | Polyester | |
|---|---|---|---|
| Water to grow | ~2,500–3,000 L / kg fiber | ~5,000–10,000 L / kg fiber | Low (no growing) |
| Pesticides needed | None — hemp is naturally pest-resistant | Among the highest-pesticide row crops globally | None (synthetic) |
| Biodegradable | Yes, fully compostable | Yes, but slower when blended | No — sheds microplastics |
| Durability | Very high — softens, doesn't weaken | Moderate — weakens with repeated washing | High, but pills and degrades |
| Breathability | Excellent — hollow fiber structure | Good | Poor — traps heat and moisture |
| Time to harvest | ~90–120 days | ~150–180 days | N/A — petroleum derived |
| Effect on soil | Improves it — deep taproot decompacts and returns nutrients | Depletes it — heavy nutrient draw | None — not grown |
| Odour resistance | High — naturally antibacterial | Low — holds bacteria and odour | Very low — traps odour |
| UV protection | High | Moderate | Varies with treatment |
| Microplastics shed | None | None | Yes — every wash |
Figures are widely cited industry estimates for conventional growing methods, not lab measurements of our specific garments — actual numbers vary by region, farming practice and blend ratio.
Cotton and polyester are the obvious comparisons, but hemp is usually weighed against linen, bamboo and wool too. Here's the honest version — hemp doesn't win every row.
| Hemp | Linen | Bamboo | Wool | |
|---|---|---|---|---|
| Softness out of the box | Good, improves fast | Good | Very soft | Varies — can itch |
| Strength | Highest of the four | High | Low–moderate | Moderate |
| Wrinkle resistance | Moderate | Low — creases easily | Moderate | High |
| Water to grow | Low | Low–moderate | Low, but chemical-heavy to process | High (livestock) |
| Processing chemicals | Minimal | Minimal | Heavy for viscose-type bamboo | Moderate (scouring) |
| Warm-weather comfort | Excellent | Excellent | Good | Poor |
| Animal-derived | No | No | No | Yes |
Generalised comparisons for typical commercial versions of each fiber. "Bamboo" here means viscose-process bamboo, which is what most bamboo clothing actually is — mechanically processed bamboo linen is rarer and behaves more like hemp.
Hemp fiber is naturally hollow, which lets air circulate through the weave. That's why hemp clothing regulates temperature instead of trapping heat the way tightly-woven synthetics do.
Hemp has natural antibacterial properties, so it resists the odour-causing bacteria that build up in sweat-heavy fabrics — you get more wears between washes.
Hemp fiber blocks a meaningfully higher share of UV radiation than cotton at the same weave density, which is part of why it's held up so well historically in outdoor and workwear use.
Unlike synthetics that degrade and pill, hemp fiber physically softens with every wash — the more you wear it, the better it feels, for years rather than months.
The same hollow structure that keeps hemp cool in heat traps a layer of warm air in cold — one fabric that works across seasons instead of two wardrobes.
Hemp absorbs and releases moisture faster than cotton, so it pulls sweat off the skin and dries quickly rather than staying heavy and damp against you.
Grown without pesticides and finished without the synthetic softeners common in fast fashion, hemp is a low-irritation choice for reactive or sensitive skin.
Hemp's fiber structure holds dye deep rather than only at the surface, so colours fade noticeably more slowly across repeated washes than they do on cotton.
Beyond the headline numbers, these are the differences you actually feel in a garment — or that the planet feels on your behalf.
Values are indexed scores (100 = highest in that row) built from widely cited industry estimates for conventional growing and processing — they illustrate relative differences between fibers, not laboratory measurements of our specific garments. Real figures vary with farming practice, region, blend ratio and finishing.
Hemp is low-maintenance by nature. Four habits keep a garment going for years instead of seasons.
30°C or below on a normal cycle. Hemp doesn't need hot water to get clean, and cold protects both the colour and the fiber.
Fabric softener coats the fiber and blocks the breathability you paid for. Hemp softens on its own with every wash — let it.
Air drying keeps hemp's strength and colour longest. If you tumble dry, use low heat — hemp handles it better than most naturals, but low is kinder.
Hemp's natural odour resistance means most pieces are fine after several wears. Airing a garment out often beats another wash cycle.
No. Industrial hemp and marijuana are different varieties of the same plant species, but industrial hemp is grown specifically for fiber and contains negligible THC (well under legal limits) — it has no psychoactive effect. It's a textile crop, the same category as flax or cotton.
Older, 100% hemp canvas could be coarse, which is where that reputation comes from. Modern processing and hemp-cotton or hemp-viscose blends (what we use) produce a soft hand-feel from the first wear, and it keeps softening after that.
Roughly comparable to premium organic cotton at similar weights. It costs more than fast-fashion synthetics, but the durability means a lower cost-per-wear over the garment's life.
Machine wash cold, similar to cotton. Line-dry when possible to keep colors and fiber strength longest, though hemp tolerates tumble drying on low better than most natural fibers.
Untreated hemp fabric is fully compostable. Blends (like our hemp-cotton pieces) biodegrade more slowly depending on the other fiber and any dyes used, but still break down far faster than synthetics.
