After competing in the 2018 Winter Olympics, co-founder Kiley McKinnon saw firsthand the need for technical apparel designed specifically for women—not just scaled-down versions of men's products. Together with co-founders Ariana Ferwerda and Karelle Golda, she founded Halfdays to bring a fresh perspective to the outdoor industry through performance-driven apparel that blends technical innovation with modern design.
Since launching in 2020, Halfdays has grown beyond its ski roots into a year-round outdoor brand, creating versatile apparel for hiking, golf, tennis, travel, and everyday adventure. While the brand has expanded across seasons, the same philosophy remains at its core: thoughtfully designed technical products that empower more women to get outside with confidence, comfort, and style.
