Re-checked daily
Oiselle — French for "bird" — is a women's running apparel company started by Sally Bergesen in Seattle in 2007.

Oiselle made its name backing women runners directly: it was the first women-only brand to sponsor college athletes, supplying uniforms for Yale's track and cross-country teams, and in 2013 the first brand to sponsor a pregnant athlete. Its roster, guided by athlete advisor Lauren Fleshman, has included Kara Goucher and current runners such as Allie Ostrander. In 2023 the brand merged with fellow running label Janji.

Oiselle shopping FAQ

Is Oiselle running apparel worth it?+

For runners who want gear designed specifically around women's bodies, most reviewers say yes. Oiselle's prices sit in the mid-to-upper tier of running apparel, but the moisture-wicking, four-way-stretch fabrics are praised for holding their shape wash after wash, and many fans report still wearing pieces a decade later. If durability and a women-first fit matter more to you than the lowest price, it is an easy recommendation.

How does Oiselle compare to Lululemon for running?+

Oiselle tends to specialise in fitted, run-focused pieces like the Roga short and the Pocket Jogger, with serious attention to anti-chafe coverage and storage, designed by and for women runners. Lululemon leans more toward a looser, casual-aesthetic style that crosses over into general athletic wear. If your priority is purpose-built running kit rather than versatile athleisure, Oiselle is the more specialist pick.

What does the name Oiselle mean?+

Oiselle is French for bird, a fitting name for a brand built around the feeling of flight that runners chase. It captures the lightness and freedom the apparel is designed to give, and it has become shorthand for the brand's running-obsessed community.

Who founded Oiselle, and when?+

Oiselle was started by Sally Bergesen in Seattle in 2007. It remains a woman-founded and woman-led brand, which is central to its identity and to its long record of championing female athletes of all ages and body types.

What makes Oiselle different as a women's running brand?+

Oiselle was the first women-only brand to sponsor college athletes, providing the uniforms for Yale's track and cross country teams, and in 2013 it became the first brand to sponsor a pregnant athlete. That willingness to back women at every stage, rather than treat them as an afterthought, is what sets it apart from larger unisex labels.

Which professional runners has Oiselle supported?+

Oiselle has long sponsored professional athletes, with Lauren Fleshman serving as an athlete advisor, and runners such as Kara Goucher have been part of the roster over the years. As of early 2025 its sponsored athletes have included Carmen Graves, Maria Michta-Coffey and Allie Ostrander. The brand's credibility comes in large part from this deep tie to competitive women's running.

Did Oiselle merge with another running brand?+

Yes. In 2023, Oiselle merged with fellow running brand Janji. The two share a runner-first, community-minded ethos, and the merger brought together complementary strengths in women's performance apparel and adventure-running design.

Which Oiselle piece should I buy first?+

A pair of shorts is the natural entry point, since that is where Oiselle's anti-chafe, run-specific design shows best. The Roga short is the light, quick-drying everyday option, while the Pocket Jogger is the choice if you want serious storage and zero ride-up over longer distances. Either gives you a clear feel for the brand's fit philosophy before you build out the rest of your kit.

Is Oiselle good for runners of different body types?+

It is a core part of the brand's promise. Oiselle is fit-tested by women, for women, and openly supports female athletes of all ages and body types. Reviewers describe the pieces as comfortable, flattering and functional, which is exactly the brief a women-first running label sets out to meet.

When is the best time to buy Oiselle?+

Oiselle sits at higher-end pricing, so the most reliable savings come from its sale section, which reviewers note often runs meaningful end-of-season markdowns on past colourways. Build your wardrobe around timeless staples like shorts and tights first, then add seasonal pieces when they clear. As always, fit should lead the decision over the size of the discount.
