What Halfdays does

Halfdays is a women-led outdoor apparel company founded in 2019-2020 by former Olympic freestyle skier Kiley McKinnon alongside co-founders Ariana Ferwerda and Karelle Golda, headquartered in Denver, Colorado. The brand was created to address what the founders identified as a gap in technical, stylish outdoor apparel designed specifically for women's bodies, sitting between purely technical outdoor incumbents and luxury fashion labels lacking performance features. The product portfolio centers on snow outerwear (ski jackets, pants, and bibs with waterproof ratings up to 20,000mm and PrimaLoft insulation), thermal base layers in merino and bamboo, the UPF 50+ GwenUV sun protection line, trail apparel, and performance activewear, with pricing from $20 for accessories to $575 for premium outerwear. Technical credibility is delivered through licensed performance fabrics including PrimaLoft insulation, GORE-TEX waterproofing, brrr° Triple Chill Effect cooling, and drirelease moisture management rather than proprietary materials.

The company operates an omnichannel go-to-market: direct-to-consumer e-commerce through halfdays.com (powered by Shopify, with free US shipping over $95), a Denver flagship store opened in December 2024 at 2609 Walnut Street, and selective wholesale partnerships with REI (since November 2024), Nordstrom (since November 2022), Dick's Sporting Goods, Shopbop, and Revolve. Halfdays also generates revenue from limited-edition collaborations, most notably a November 2025 HOKA footwear partnership, an ILIA Beauty ski kit, a Parks Project line, and a Mako Matcha activation. The Second Lift pre-loved program, powered by Trove, provides a circular commerce channel for returned and restored products. Reported metrics include a 40% repeat-purchase rate and projected 2024 revenue of approximately $25 million, representing roughly 80% year-over-year growth, with international shipping to the US, Canada, Australia, the UK, Mexico, and New Zealand.

Halfdays has raised approximately $15 million in lifetime funding across multiple rounds, with the most recent being a $10 million Series A in October 2025 led by apparel brand-management firm Kellwood Company, with participation from Dick's Sporting Goods Ventures, DSG Ventures, and influencer Taylor Hill, at a $40 million pre-money valuation. Use of proceeds is earmarked for product line expansion across winter, ski, trail, and activewear, wholesale scaling, and brick-and-mortar retail. The brand emphasizes community engagement through a dedicated Slack channel (Halfdays Chalet), recurring city-based events (Pilates meetups, trail hikes, pop-ups, brand activations), and trade-show presence including a Paris Fashion Week SS27 showroom, supported by marketing channels spanning Instagram, email and SMS, fashion media placements, and influencer partnerships.
