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.

From product innovation to supply chain responsibility, we’re proud of the progress we’ve made, and transparent about the work that still lies ahead. This is our way of staying accountable, sharing our journey, and pushing for better at every step.
