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.

I have purchased several styles of the sports bras for my wife, but she loves the Infinity Sports bra the most!
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 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.)
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!
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!
Love the feel of the fabric and the fit of this bra. I paired it with the with the W's 3" AFO Rhythm Short. The Dandelion looks amazing on a tan. I am a 34 A and purchased a size Small.
Love the color. Well made and med/strong support.
Bonito 🫶🏻
Comfy and supportive. No rubbing after a hot 50K. Great purchase!
