The Sierra Sports Bra by Mons Royale is a sports bra made of merino wool with a polyamide core and elastane content, which fits perfectly with the breathable racer back made of merino mesh and feels velvety soft on the skin. No matter how hard you train, this sports bra can keep up with you. Thanks to the anti-odour properties of merino wool, the Sierra is also perfect for multi-day backcountry adventures.
