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.

LOVE this bra. It’s so comfortable and can be worn alone without a shirt… and can we talk about the back pocket? Why does anyone make a bra without a pocket anymore?

I’m usually between an XS and a S in sports bras and I bought a XS… loved it so much I didn’t exchange it but I should’ve bought a S.

Anyways, give us more colors!!

Loving the long bra!

This bra is so great for long runs - no chafing and a convenient (no-bounce!) pocket for phone or gels. I love the length for a bit more coverage but still super breathable. I am small-chested, so larger cup sizes may have to size up. Janji for life!

Love the long bra! More colors, please!

This bra is amazingly comfy for longer runs. Looove the pocket in the back for my phone! The only problem with this bra is that it needs to come in more colors!

3 in one top

Love it! It works as a sports bra, top, and phone holder all in one, it's perfect. The phone pocket was a little weird to get used to at first, cause i often pull my phone out and put it back during a run, but the phone actually slides into the pocket pretty easily. Phone doesn't bounce around or anything during the run, it's really perfect.

I have tried long-line bras and cropped running tops w/built-in bras from other companies and I always find them uncomfortable around the rib cage. No problems like that here! Super comfortable, no pinching and love the removable pads. Perfect for hot weather running. I’ve bought a couple and will buy again.

My new go-to

Well constructed, but really all about the phone pocket. I took a tumble on a trail run this weekend in this top and fell on my palms and knees. So glad I wasn’t holding my phone as I normally am. It was snugly tucked in my back and unharmed.

the perfect sports bra/crop top

I bought this sports bra/top because I was experiencing chafing (for the first time ever!) while marathon training this past spring. I was really hopeful this long bra would be the fix and... it was! I have never experienced any chafing with this top (hallelujah!), and it's super comfy and supportive enough for me (34C) without being too compressive. I've never been a crop top wearer, but this one is so cute and supportive that i've started running in just this top in the hot summer months - it's been a total lifesaver (and confidence boosters) during this sweaty midwest summer!! I also love the phone pocket on the back - I don't often use it, but it's handy when i do need it.

Best running sports bra

I came across these on Instagram. I had been looking to replace bras with a back pocket I bought a few years ago. My search has ended!! I love these so much!! I bought 2 black and ordered a 3rd in pink. They are so good. I can’t wear my old ones anymore. I love that they are long enough to be worn as a crop top too. Great support and true to size. I wear XS (34b in a regular bra 5’5” 124lbs)
