Sustainability

Groundwork Knit is made using a premium grade nylon that has a significantly tighter woven filament than standard synthetics. Tighter filaments mean less microfiber shedding in the wash-cycle, plus greater durability of the garment (longer lifespan, more wearing).

Groundwork Knit fabric is also bluesign® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.

Favorite print

I am obsessed with this print. It is so beautiful. I love that this sports bra is reversible. It does not cause chaffing even on long runs.

Just what a long distance bra should be

Just as it says no fuss bra. No spongy cups to hold extra water, no clasps to rub or chafe, enough compression to get along with living on earth- with gravity. I ordered a originally ordered a medium immediately washed and got it ready to run in and realized it was too big- moved across my skin, found a friend to pass it on to as I couldn’t return it after washing and wearing, bought a small and it’s perfect. (I’m generally 34-36 B or C depending on the bra maker.)

Fantastic

The design is bright and beautiful and unique, and the bra itself is comfortable during activity. I bought this with shorts and hat, and I love the combination!

Like butter

Love this bra. Soft, supportive and not excruciatingly tight. I like the coverage especially under a pack to reduce chaffing. Perfect. I need three more.

Keeps the girls on lockdown, dries fast, and no chafing. I’m getting another as soon as I can because I LOVE that they are reversible! So versatile!
