When support starts rubbing

Support shouldn’t come with raw skin.

A sports bra can feel perfect when you leave home. Add sweat, salt and thousands of repeated arm swings, and the band, seams or straps can turn into the only thing you can think about.

Sports bra chafing usually starts small. The longer you move, the harder it becomes to ignore.

The real benefit

The goal isn’t to feel Run Slick.
It’s to forget about the rub.

Your attention belongs on your pace, your workout and where you’re going — not the line under your bra band.

Sports bra chafing questions.

How do I use Run Slick under a sports bra?

Apply an even layer to clean, dry skin where your bra usually rubs. Give it a few seconds to settle before putting on your sports bra and getting moving.

Where should I apply it?

Common contact points include the under-bust band, side seams and underarm edges, shoulder straps and racerback edges. Apply it wherever you know friction starts.

Does it feel greasy or waxy?

Run Slick is designed to feel lightweight and silky rather than thick, greasy or waxy on skin.

Will it stain my sports bra?

Run Slick is designed to be fabric-safe. For best use, apply it to clean, dry skin and give it a moment to settle before dressing.

Will it hold up to sweat?

Run Slick is designed for sweat-resistant performance and repeated movement, and it is also water resistant.

Do I need to reapply?

For very long efforts, repeated water exposure or heavy rubbing, reapply as needed based on your duration, conditions and individual friction points.

Your sports bra should support the run.
Not distract from it.

We’ll handle the friction.
