437 Active

437 Active, a dynamic brand emerging from Toronto, Canada, is reshaping the landscape of activewear and swimwear. Founded in 2017 by best friends Hyla Nayeri and Adrien Bettio, the brand originated from their shared frustration over the lack of flattering and functional swimwear options. The name “437” pays homage to their university address where their entrepreneurial journey began. Originally focused on swimwear, 437 has since expanded into activewear, offering a range of stylish and high-quality pieces that prioritize comfort and fit. The activewear collection features a variety of tops, bras, bottoms, and accessories made from unique fabrics like 437smooth™ and 437cloud™, designed to move seamlessly from workout to daily wear. Their pieces are available in a range of sizes from XS to XXL, ensuring inclusivity and a perfect fit for all body types.
