Built for race day. Designed for every day.

We teamed up with Boulderthon to create a sports bra that goes the distance—whether you’re chasing a PR on Pearl Street or cruising through a recovery run. This limited-edition piece blends Cooldown’s no-bounce support and soft, sweat-wicking fabric with Boulderthon’s mountain-town spirit.

Why We Made This

🏃 Support You Can Count On
Running is tough enough—you shouldn’t have to worry about your gear. This bra offers reliable support, so you can stay focused on every stride.

📱 Secure & Connected
Your phone is your lifeline on the go, whether for safety or tunes. That’s why we added a discreet back pocket to keep it secure, so you can run with peace of mind.

💨 Convenient Storage
Need extra space for gels, cards, or other small essentials? We've got you covered with two side pockets, providing easy, accessible storage without interrupting your flow.

🔥 Style That Goes the Distance
Tired of sports bras that only perform but don’t flatter? Us too. This bra combines technical performance with a sleek, stylish design—so you’re ready for miles or mimosas.

✨ Made for Runners
Designed with your comfort in mind, this bra features a breathable band, supportive straps, and soft, chafe-resistant fabric—because nothing should slow you down.
