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.

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!

GREAT bra

I love this Janji bra. Super comfortable with no chafing. I sized down to a small for extra support and it’s just perfect. I would say it runs slightly large, but it really depends on how you like it to fit. I wear a 34C bra and the small fits perfectly.

Excellent for Running

I'm a size 34C in regular bras. The M felt slightly slug pulling it on the first time or two, and in fact I considered sending it back. However, after wearing it a couple of times, it's the perfect size. Looks super cute and everything stays in place. I've worn it for a long run without any chaffing.

Love this sports bra!

Love the fun pattern and the fit. Perfect for long runs because it has support but is not at all restrictive. Super comfortable and my go-to sports bra!

What I've been looking for

Simple yet perfect. Too many sports bras are trying to do too much these days, this offers the support I need with comfort that I can wear all day. The bright colors are an added benefit.
