Performance Comparison: Hemp vs. Polyester
The choice of fabric can significantly influence athletic performance. Hemp and polyester each bring their own strengths to the table, but they behave quite differently under the demands of intense physical activity.
Breathability and Moisture Management
Hemp stands out for its natural breathability, thanks to its porous fiber structure that promotes air circulation. Its hollow fibers actively draw moisture away from the skin, creating a cooling effect that’s especially helpful in warmer conditions.
Hemp can absorb up to 30% of its weight in moisture while still feeling dry to the touch. For example, under typical conditions (65% relative humidity), it absorbs about 12% of its weight, but this can rise to 30% in high-humidity environments (95% RH at 68°F).
Polyester, being a dense synthetic fiber, doesn’t absorb moisture. Instead, it relies on engineered moisture-wicking properties to move sweat to the surface of the fabric for faster evaporation. However, polyester’s inability to breathe naturally can trap heat and moisture against the skin, potentially causing discomfort during hot or humid conditions.

Hemp also has a natural edge when it comes to odor control. Its resistance to bacteria, mold, and mildew helps minimize odor buildup during long games or practices. Polyester, on the other hand, often requires chemical treatments to achieve similar antimicrobial effects, but these treatments can wear off after multiple washes.
Durability under stress is another key factor where these fabrics differ.
Durability and Longevity
Hemp is one of the strongest natural fibers available, offering impressive resistance to wear and tear from rigorous physical activity, frequent washing, and rough handling. What’s more, hemp actually becomes softer and more comfortable with every wash – all while retaining its strength. These qualities make it an excellent choice for team uniforms that need to last.
Polyester, meanwhile, is celebrated for its ability to maintain its shape and stretch even after months of regular use. This durability has helped polyester dominate the athletic apparel market, where it accounts for more than 50% of the total fiber market.
However, when it comes to long-term performance, hemp offers a distinct advantage. While synthetic fabrics like polyester can initially resist deterioration, they may lose elasticity and shape over time. Hemp, by contrast, improves in comfort as it ages without compromising its durability.
Weight and Flexibility
Advances in processing have made hemp surprisingly flexible, allowing it to stretch and move with the body naturally. This gives athletes a full range of motion without feeling restricted. Hemp also provides temperature-regulating benefits: it insulates when the body is at rest and cools during activity, making it adaptable to various levels of exertion.
Polyester, particularly when blended with spandex, offers excellent stretch and shape retention. However, nylon-spandex blends are often better at delivering the stretch and flexibility needed for more demanding sports.
For athletes with sensitive skin, hemp offers a hypoallergenic option that becomes increasingly comfortable over time. Its moisture-wicking and temperature-regulating properties make it a great choice for extended wear during long practices or tournaments.
Environmental Impact of Hemp and Polyester
When choosing sportswear fabrics, the environmental impact plays a bigger role than ever. Hemp and polyester differ greatly in how they affect the planet, from the resources needed for production to their behavior at the end of their lifecycle.
Production and Resource Use
Hemp stands out as a low-impact option. Producing one kilogram of hemp requires just 300–500 liters of water and absorbs an impressive 10 tons of CO₂ per hectare annually, outperforming many conventional fibers. In fact, hemp plants capture four times more carbon dioxide than other crops. As Bailey Pyman aptly put it, “Switching to hemp promotes healthier ecosystems, cleaner waterways, and a more sustainable future.”
Polyester, on the other hand, tells a very different story. As a petroleum-based synthetic fiber, its production uses 125 MJ of energy per kilogram. Projections warn that polyester could account for over 26% of the global carbon budget by 2050. Additionally, hemp farming requires significantly fewer resources – about 77.63% less investment in fertilization, seeds, field operations, and irrigation compared to cotton farming. Hemp also thrives without pesticides and even improves soil health, while polyester production depends heavily on fossil fuels and releases harmful substances into the environment.
| Environmental Factor | Hemp | Polyester |
|---|---|---|
| Water Usage | 300–500 liters/kg | Lower water needs during manufacturing |
| Pesticide Use | None | N/A |
| CO₂ Impact | Absorbs 10 tons per hectare annually | High emissions, 26% of carbon budget by 2050 |
| Energy Requirements | Low | 125 MJ per kg produced |
While production has its challenges, the end-of-life phase of these fabrics reveals even more about their long-term environmental impact.
Biodegradability and End-of-Life Impact
Hemp offers a natural advantage by being fully biodegradable. Once its life cycle ends, hemp returns nutrients to the soil, integrating seamlessly back into the ecosystem. This makes hemp uniforms an eco-friendly choice, as they won’t linger in landfills for decades.
Polyester, in stark contrast, is non-biodegradable. It can take hundreds of years to break down in landfills. On top of that, every washing cycle of polyester clothing sheds up to 60,000 tiny plastic fibers into waterways, contributing significantly to the growing crisis of microplastic pollution. These fibers remain in the environment for centuries, meaning that polyester uniforms produced today could still be polluting the planet for generations.
It’s worth noting that hemp’s biodegradability depends on factors like moisture, temperature, and microbial activity. Blending hemp with synthetic fibers like polyester diminishes its ability to decompose naturally. For the best environmental benefits, pure hemp or blends with a high percentage of hemp are ideal.
For teams looking to minimize their environmental footprint, hemp emerges as a sustainable choice that supports healthy ecosystems throughout its lifecycle. Polyester, however, presents enduring environmental challenges that extend far beyond its useful life.

When comparing costs, it’s essential to look beyond the initial price tag. While hemp may come with a higher upfront cost, its durability and environmentally friendly production methods can make it a better long-term investment compared to polyester’s lower initial price.
Initial Costs and Scalability
The price gap between hemp and polyester is significant. Pure hemp costs roughly eight times more per kilogram than virgin polyester. At 290gsm, hemp is priced at about $22 per kilogram, whereas polyester costs just $3 per kilogram. This price difference stems from hemp’s scalability challenges and the limited availability of production facilities. Hemp production also faces infrastructure hurdles, such as the lack of global certification systems and the need to rebuild supply chains in regions like Europe, where bans in the past led to expertise and production shifting to Asia.
Despite these obstacles, the hemp market is on an upward trajectory. The market for hemp clothing is projected to hit $81 million by 2030, growing at an impressive annual rate of 32.5%. Similarly, the global hemp fiber market is expected to expand from $5.76 billion in 2022 to $23.57 billion by 2030. To make hemp more accessible, some manufacturers are blending it with less expensive materials like polyester. Additionally, major players are investing heavily in infrastructure. For instance, Under Armour has committed $6 million to establish hemp production facilities in Australia.
| Cost Factor | Hemp | Polyester |
|---|---|---|
| Raw Material Cost | $22/kg (290gsm) | $3/kg (290gsm) |
| Market Growth Rate | 32.5% annually | Established market |
| Infrastructure Investment | High (rebuilding needed) | Well-established |
While these initial costs present challenges, hemp’s long-term value becomes evident when analyzed through its cost-per-wear.
Cost-Per-Wear Analysis
Hemp’s durability can make its higher upfront cost worthwhile over time. Known to be three times stronger than cotton, hemp can extend a garment’s lifespan to 20–30 years, compared to cotton’s average of 10 years. Plus, hemp clothing not only retains its strength but also becomes softer with each wash, offering greater comfort as it ages.
This extended lifespan means that the cost-per-wear of hemp garments can compete with polyester, especially when factoring in the added environmental benefits. As production scales up and technology advances, hemp is expected to become more affordable, thanks to economies of scale and ongoing innovations in the industry.
For those focused on long-term value and environmentally conscious choices, hemp’s durability and sustainability make it a compelling option despite the higher initial expense.
