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.

50 mile approved!

I just ran my first ultra in the infinity, and it was perfect! I used to run exclusively in Nike swoosh sports bra, but now that they've made sewn in pads, I don't wear them. The infinity has a very similar feel to the original swoosh but reversible, which I also really like. I experienced no chafing, and was very comfortable. I ended up sizing down. I normally wear a medium in other janji bras I have tried.

Infinity sports is very comfortable.

I purchased this to replace a regular bra. I wanted comfort with support.

comfortable and good coverage

overall a great sports bra. i would say it runs slightly large and perhaps is best for folks with bigger busts. i normally order mediums and find it to be a tiny bit loose in the bust. regardless, it's still a great bra.

Infinity Sports Bra

This bra is the best sports bra I've ever owned, especially for those looking for one for longer runs! It's colorful, which is a plus, but no chaffing and stayed in place and was comfy for my recent 20 miler! It's solid, highly recommend!

I'll be rocking it for my very first marathon in Chicago in a few weeks! Thanks Janji!
