Hat Body: 17-24 Micron Pure Australian Wool Sweatband: Soft Cotton Twill Accessory: All Natural Leather Our wool is sourced from small-lot farms in Australia. We source short, low-quality fibres the fashion industry doesn\'t use and turn them into high-quality felt products designed to last the extra mile. Wool is natural, biodegradable, recyclable, renewable, and odour-resistant. It naturally regulates temperature, meaning it\'s warm in winter and cool in summer. We use natural fibres that fit within natural carbon cycles. We only use synthetic fibres where a natural alternative is unavailable so that it won\'t cost the earth later. We don\'t mix fibres so that we can separate components for reuse or recycling.
