Heads up — some color bleed may occur
Color bleed, especially with darker colored nylon/spandex blends, is common and could stain light colored garments if washed together.

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 top

This long bra is great. I have it in two colors. It fits well and is super comfortable while running. I find that I get too hot running in it on the hottest days of the summer, but most other runs in this long bra is great. I will likely be getting more!

Obsessed!

I am obsessed with this long crop bra. The fit, the breathability of the fabric, the cut is super flattering and I LOVE the color. I've gotten so many compliments on it and feel confident wearing it without a tank or shirt on top.

Very cute, perfect for fast runs

I love this long bra! I got size small in jasper color. I felt more comfortable taking the padding out, but it was still supportive. I find that if I use it with a running pack it rolls up a bit, so I suggest using this one for pack-less or shorter runs. I get lots of compliments on it! It is definitely snug, so I could have probably gotten away with a medium too.

Better than I imagined

I was just hoping for a supportive sports bra but what I found was much more. This makes such an excellent crop top and I've been loving it on my warmer runs. The cut of it is so great and really does wonders. For size reference, I was nervous about the fit because I typically wear a small in tops but have a wide ribcage. I'm a 36C in bras and a medium provides great support.

For the roads, trails, and bars

This top is so flattering! It says long bra but it feels more like a crop top. It has a builty in shelf bra made of mesh on the inside. I am pretty small chested so it provides great support for me, but I can imagine it might not for bigger chested folks. The outer layer is made of a slick and sleek technical material, which I love. The cut on the chest is so cute and I honestly think I will wear this running but will also pair it with a cute skirt. I will definitely wear it out to a bar when the pandemic is over. I have a bit of a small waist and love handles so I will probably only wear this with a high waisted bottom because it does accentuate my love handles with low rise bottoms.

Feels like run wear, looks like street wear.

Favorite!

I love this sports bra. I'm actually excited for warmer weather where I can wear it without a shirt over it--for that reason I love the slightly longer fit. The fabric is a bit softer than the groundwork tights, but just as durable and functional. The cut of the bra is incredibly comfortable and perfect for running. The only thing that would have made this better is a back pocket--there is certainly room for one. This would make it the perfect sports bra!

LOVE

Just wore this today for the first time. Amazing! Really loved it. Very comfortable and didn’t even notice it while running. I bought the small and I wear a 34C bra. A little fitted to get on but I think the medium would have been too big. Better more fitted for a sports bra. Love this new style. Very flattering too.

Truly Superb

I'm 5'7, 120lbs, 32B and got this in a S. I am somewhere between an XS and a S in most tops because I have a wider ribcage but this fits perfectly!! It's supportive, it's sleek, and it's the perfect length. It ends just above my belly button. It fits like a second skin without feeling restrictive At All. To me, the fabric seems to be most comparable to lululemon nulux. This may be my new go to race top. In a previous version, it felt like there was too much material around the arm opening but that is totally fixed with this version. 100% recommend!! Couldn't be happier.

Groundwork bra and shorts

I bought both the groundwork long bra and shorts. I love them both. They don’t ride up and I haven’t had chafing so far. The only issue I’m having is that I’ve worn each 3-4 times and they turn my skin yellow when I sweat in them. It’s like some dye is leaching out. I’m hoping that will eventually stop.
