Activewear that inspires and provides a solution-sewn in pads!

Day 1 Fitness isn’t just another activewear brand—it’s a movement built to support women from the inside out. When founder Kalee Rogers came to Thread Vision, she had a clear mission: create a performance-driven line that would take over the world—starting with a problem no one else was solving. Her solution? Built-in bra pads sewn directly into every piece. No shifting, no extra layers, just smart, seamless support designed for real women who train hard.  

Because of the high level of customization, every product was built entirely from scratch by Thread Vision—from concept and technical design to sourcing, sampling, production, and fulfillment. Day 1 has quickly grown into a multi-figure brand with hundreds of glowing reviews and a fiercely loyal customer base. This is what happens when bold vision meets the right partner.

We don’t just make apparel—we bring category-changing ideas to life.
