Materials

Cotton

A soft, breathable, absorbent, and versatile natural fiber grown from the fluffy bolls of cotton plants.

Good to know: Conventional cotton is one of the world's dirtiest crops as cultivation heavily relies on pesticides, herbicides (glyphosate), and fertilizers, raising concerns about environmental pollution, soil health, and potential health risks for farmers and consumers. This is why some brands and consumers push for "100% organic cotton." Organic cotton skips the harsh chemicals, making it a more eco-friendly and healthier choice.

Wool

Wool is a natural protein fiber obtained from the fleece of sheep and other animals, including alpacas, goats (such as cashmere and mohair goats), and rabbits (like angora). It's known for its durability, insulation properties, and ability to absorb moisture without feeling wet.
