Hemp will take good care of you, especially if you take good care of it. Below are some suggested tips for taking the best care of your hemp.

HEMP + ORGANIC COTTON BLENDS:

• Machine wash cool, gentle with like colors.
• Tumble dry, low heat. 
• Do not use spot laundry cleaners, bleach or other chemical and enzyme cleaners like oxi-clean. 
• Take care not to wash with garments with zippers or velcro or towels with texture as this will cause abrasion and pilling.

HEMP +  WOOL BLENDS:

• Follow the same instructions as above for Hemp + Organic Cotton blends, but be extra careful to only tumble dry on very cool settings. Laying flat to dry is the best way to maintain integrity of wool fibers.

Hemp is a naturally strong, durable fiber, which is why we use it to make clothing you'll wear for years. It's also a remarkable crop: in the right conditions, it grows with relatively little irrigation and fewer chemical inputs than cotton.

The facts:

1. Stronger fiber than cotton. In a peer-reviewed comparison, hemp fibers measured 310–850 MPa in tensile strength, compared with 287–597 MPa for cotton. [BioResources, NC State University]

2. Resists pilling and wear. In 2025 lab testing of woven bast-fiber fabrics, hemp earned the highest pilling-resistance rating of the fabrics tested, holding up across repeated wear cycles. [Fibres & Textiles in Eastern Europe, 2025]

3. Uses less water. Hemp uses about 38% less water than cotton over a growing season, and its water footprint is roughly 60% lower. [Journal of Agrometeorology, 2023; Journal of Cannabis Research, 2025]

4. Needs fewer pesticides than cotton. Cotton is one of the most pesticide-intensive US field crops, with 42 million pounds applied across 10.3 million acres in 2021. Hemp is typically grown with substantially less pesticide input. [USDA data via Organic Trade Association]

5. Captures carbon as it grows. Published estimates put hemp's CO₂ uptake at roughly 3–15 tonnes per hectare during cultivation. At the higher end, that outpaces the 2–6 tonnes per hectare per year typical of forests. [Portland State University review; University of Cambridge research]

6. Can help clean soil. Hemp roots can absorb low levels of heavy metals such as cadmium, lead, and zinc from soil. This process is called phytoremediation. [Portland State University review]
