Girls in Sport Week: Encouraging Young Athletes to Stay Active

At Girls in Sport Week hosted by Nanaimo United FC, we connected with young athletes and parents to spark conversations about menstrual health, performance, and the gear that helps girls stay confident in sports.

Empowering Women Who Empower Girls

We joined the Hettas x BeaYOUtiful Mentor Movement in Vancouver, Calgary, and Toronto, celebrating women who mentor young girls. We connected with female-led brands and communities dedicated to confidence, self-love, and empowerment.

Celebrating Women at the BMO Marathon Expo

We were proud to be part of this year’s BMO Marathon Expo, cheering on female runners and celebrating the power of movement. It was an inspiring reminder of why supporting women in sport matters, on the course and beyond.

Finding Strength on the Trail: Our Team Hike Experience

Our team hit the trails for a hike that challenged us, connected us, and reminded us of the power of movement. It also gave us the perfect chance to put our leakproof products to the test in real-world conditions.

Why Leakproof Underwear is a Game-Changer for Athletes

Pads shift. Tampons need changing. For athletes, that means distractions you can’t afford. Leakproof underwear keeps you protected, comfortable, and focused, no matter the workout.

Our Story

Women’s performance gear has too often prioritized form over function. After years at brands like Lululemon and Aritzia, we saw the same flaw; products that looked good but didn’t hold up when it mattered.

In 2020, we founded Athleticus Research with a clear goal: to create apparel where form and function work together. High-performance gear that supports women every step of the way, anytime of the month.
