Outerknown Run

Frequently Asked Questions

• What materials does Outerknown use in its running clothing, and why does that matter?

  Outerknown relies on organic, recycled and regenerated fibers—examples include 100% organic cotton, hemp blends (commonly 55% hemp / 45% organic cotton) and recycled polyester made from water bottles—so pieces prioritize lower environmental impact, durability and breathable, natural-feeling performance. The material choices affect moisture handling, weight and lifespan, so picking the right fabric helps match the garment to your running conditions.
• Are Outerknown running pieces suitable for intense, high-sweat workouts?

  Many Outerknown styles use recycled and regenerated fiber blends that offer better breathability and quicker drying than heavyweight natural-only garments; look for lighter recycled-poly blends for high-sweat sessions. Hemp blends are exceptionally durable, naturally odor- and UV-resistant, and breathe well, but heavier hemp-forward pieces may feel warmer than technical poly blends during very hot, intense efforts.
• How does a hemp-blend running tee compare to a 100% organic cotton tee for running?

  A hemp-blend (e.g., 55% hemp / 45% organic cotton) is significantly stronger and more resistant to UV and mildew than 100% organic cotton, so it holds up better over time and resists odors; it also breathes well but can feel a bit sturdier initially. A 100% organic cotton tee is softer off the rack and comfortable for lower-intensity runs, but it absorbs moisture and generally takes longer to dry than blends containing recycled polyester or hemp.
• How should I size Outerknown running apparel—do they run true to size?

  Outerknown garments typically have a slightly tailored, structured fit that balances comfort with a flattering silhouette; many people find them true to size. For a looser fit or layering, consider one size up and always consult the product-specific size chart and measurements provided on the item page.
