Under Armour Signs Tinx and Launches “Summer of Outside” Event Series

Under Armour has officially announced creator, entrepreneur, and bestselling author Tinx as its newest brand ambassador, adding one of social media's most recognizable personalities to its growing roster of partners.

The partnership spans both apparel and footwear and arrives as Under Armour continues to expand its approach to performance, embracing the idea that movement and wellness can take many forms beyond traditional training.

To kick things off, Under Armour and Tinx are launching "Summer of Outside," a new community-driven event series inspired by the creator's popular initiative encouraging people to spend less time on their phones and more time outdoors.

The series will visit San Francisco, Chicago, and New York City this summer, bringing together movement, community, and wellness through a variety of experiences. Each stop will feature group activities, product giveaways, Christina's Café pop-up experience, and opportunities for attendees to disconnect from their screens and reconnect with others.

"I've always believed that feeling good doesn't have to be complicated," Tinx said. "Sometimes it's a workout. Sometimes it's a walk with friends. Sometimes it's just about getting outside and putting your phone away for a while."

Beyond the event series, Tinx will also curate "Tinx's Picks," a rotating collection of her favorite Under Armour apparel, footwear, and everyday essentials. The partnership will continue throughout the year with content, product storytelling, and community-focused experiences designed to reflect how women actually move through their daily lives.

Known for her SiriusXM show It's Me, Tinx, her New York Times bestselling book The Shift, and her large social following, Tinx has built a loyal audience through her relatable approach to confidence, wellness, and modern life. Under Armour sees the partnership as an opportunity to connect with women through a broader definition of performance—one centered on feeling good, building healthy habits, and showing up for yourself every day.

The first "Summer of Outside" events are set to begin this summer in San Francisco, Chicago, and New York City.
