DAY/WON
Rated: Good
Price: $$
Location: USA
Quick verdict
Best for women of all sizes (0–32) seeking high-performance, sustainably made activewear. Particularly athletes who have struggled to find technical activewear in extended sizes, founded by supermodel and marathon runner Candice Huffine, the brand uses recycled polyester and on-demand manufacturing in New York. The key caveat: DAY/WON is a very small operation with no third-party certifications, limited recent press, and the website returned error codes during research, raising questions about current operational status.

DAY/WON sustainability rating
Our ratings are based on a scale from 1 (We Avoid) to 5 (Excellent). How we rate
Rating breakdown
Primary fabric is 88% recycled polyester / 12% spandex (MaxDri technology) with sweat-wicking, antimicrobial, and compression properties. All prints are digitally constructed, eliminating water dyeing. However, specific fabric sourcing origins are unclear and there are no third-party material certifications.
All products manufactured by Ziel Wear in upstate New York, meaning compliance with US labour laws. However "no evidence it ensures payment of a living wage" and "no evidence it audits any of its supply chain." No Fair Trade, SA8000, or other labour certifications exist.
The on-demand/made-to-order model is a genuine sustainability differentiator, eliminating overproduction and inventory waste entirely. Digital printing eliminates water dyeing. However, no published environmental metrics, no carbon footprint data, and no end-of-life or circularity programmes.
Shares basic sustainability information (recycled materials, on-demand model, US-made) but publishes no impact reports, supply chain maps, factory audit results, or environmental data. Overall disclosure level is minimal.
Leggings range from ~$59–$89, comparable to Girlfriend Collective (~$78–$98) and below lululemon. Given US manufacturing, recycled materials, on-demand production, and full size range (0–32), the pricing represents solid value.
What they do well
- Unmatched size inclusivity with every single piece available in sizes 0–32 (XS–5XL): no exceptions, no "selected styles only"
- On-demand manufacturing eliminates overproduction. Products are made only when ordered, generating zero inventory waste
- Made in the USA with recycled materials at a single facility in upstate New York, reducing supply chain emissions
- High-performance technical fabrics that are marathon-tested, sweat-wicking, and antimicrobial, designed for serious athletes, not just athleisure
Room for improvement
- No third-party certifications or labour verification. No B Corp, Fair Trade, OEKO-TEX, GOTS, or bluesign
- Limited environmental data and no circularity programmes. No published carbon footprint, water usage metrics, or impact reports.
About DAY/WON
DAY/WON was founded in 2017 by Candice Huffine, an IMG supermodel and marathon runner who has been a pioneering force for plus-size representation in fashion (Vogue Italia cover 2011, first plus-size model in Pirelli Calendar 2015). While training for the Boston Marathon in 2016, Huffine discovered a "shocking lack of high-performance activewear for women over size 10."
All products are manufactured on demand in upstate New York using 88% recycled polyester / 12% spandex fabrics with sweat-wicking, antimicrobial, and compression properties. Prints are digitally constructed (zero water dyeing). The on-demand model means nothing is produced until a customer orders it, eliminating overproduction.
DAY/WON is strictly DTC with pricing from ~$19 (accessories) to ~$89 (leggings). The brand has been featured in SELF, Women's Running, Women's Health, WWD, and Refinery29.
