Castor Oil Stay Cool Chub Rubs® in Black are made using yarn derived from the castor oil plant, a hardy crop that thrives in poor, drought-prone soil and helps farming communities grow a meaningful, sustainable livelihood. These plants grow on land that can't support food crops, require very little water, and actively absorb CO2 as they grow, making them a brilliant renewable source for high-performance yarn. This makes a fabric that performs exactly like your favourite Chub Rubs - silky soft, breathable, stretchy, and gloriously cooling - but with a lower environmental footprint. So you get the same thigh-saving magic you know and love, with a little extra feel-good factor woven in.\nWhy You'll Love Them\n\n🌱 Plant-based yarn from the castor oil plant - a renewable crop that grows on marginal land with very little water\n🌍 Lower environmental impact - the plants absorb CO2 as they grow and don't compete with food crops\n✨ Stay-put waistband with multi-directional ribbing - once they're on, they stay put all day\n❄️ Cooling fabric that keeps you up to 1°C cooler while worn, stopping friction, stickiness, and inner thigh chafing\n🌬️ Lightweight, breathable, and quick-drying for all-day comfort\n","images":["https://cdn.shopify.com/s/files/1/2784/3408/files/Amy-Size-G-Biotights-Chub-Rubs-_4.jpg?v=1775052521","https://cdn.shopify.com/s/files/1/2784/3408/files/Lucy-Size-G-BioTights-Chub-Rubs-_2.jpg?v=1775052521","https://cdn.shopify.com/s/files/1/2784/3408/files/Lucy-Size-G-BioTights-Chub-Rubs-_1.jpg?v=1775052521","https://cdn.shopify.com/s/files/1/2784/3408/files/Amy-Size-G-Biotights-Chub-Rubs-_1.jpg?v=1775052521","https://cdn.shopify.com/s/files/1/2784/3408/files/Amy-Size-G-Biotights-Chub-Rubs-_2.jpg?v=1775052521","https://cdn.shopify.com/s/files/1/2784/3408/files/Amy-Size-G-Biotights-Chub-Rubs-_3.jpg?v=1754580119","https://cdn.shopify.com/s/files/1/2784/3408/files/Lucy-Size-G-BioTights-Chub-Rubs-_3.jpg?v=1754580119"],"price":10.99,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-18T20:43:35.595Z"},"share_url":"https://firestarter.network/l/lst_B1TV5lA3","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
