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.

THE BACK POCKET IS LIFE

The back phone pocket is amazing. I don't like to carry much on shorter runs, but I always like to have my phone for music, maps, etc. and I hate wearing a belt, but a vest feels excessive. The back pocket on this top is perfect for it. I was skeptical that it would bounce too much with my giant heavy phone case but I barely noticed it was back there. Also super easy to put your phone in there. New favorite running top for sure.

Soft, supportive, feels amazing!

I’ve been loving wearing this. The cut is perfect — the armholes and sleeves somehow hit just right to avoid any kind of chafing or slipping, and the cropped length is great. There are soft cups that provide more support than I expected, and also allow me to wear this on its own as a crop top. Pairs really nicely with Janji’s Repeat Merino Tech Tank, which I also love. I’ve been wearing this on runs, but also really like it for intense yoga classes — it achieves that great combo of both staying in place and keeping everything in place. For reference, I am usually between a small and a medium in tops, and usually wear a small in Janji, but went with a medium in this and it’s a great fit (34C bra size, 35-36” chest measurement). Please keep this around Janji!

Pleasantly Surprised!

I bought this top with the intention of wearing it for lower impact sports, as I am size 32DD and usually tops with built-in bras don't really work for me. This top is surprisingly supportive! I love it for climbing as the racerback cut provides excellent shoulder mobility, and it has been a go-to top for cycling. Biggest surprise, however, is that this is supportive enough I can run in it! Because of this, I bought 2 more in different colors. Nice product!

New FAVORITE!!!

I have been on the search for the perfect running crop with a phone pocket, and THIS IS IT! I love the fit, the fabric, the support, and the ease of use for the pocket! I look forward to using these (yes, plural as I am ordering more!) on all of my outdoor runs!

Didn't expect to love it

But I do! I'm 4'11", 110 pounds and more rectangular-shaped than hourglass. I'd didn't try the Groundwork Long Bra because I expected it to pinch in the waist if the top was supportive enough to stop the bounce, or to not be supportive if it wasn't too tight in the waist. However, I caught it on sale and thought it would be worth a try. I'm so glad I did! The long part of the bra is not binding at all, and when it gets sweaty, the material is very cooling. The top is supporting without crushing. I reach for this bra every time it's clean, and when it's long run day, I'll even wear it dirty. Can't wait to try the 2.0 version.

LOVE

I've had my eye on these for a long time now, starting with the first version, and I couldn't resist once the back pocket was added. It's everything I was hoping for. The cut is super cute in the front and the top is so functional. This one top replaces three items for me (bra, shirt, phone holder) which is just so satisfying. I usually wear a S in tops but a M in sports bras and this top in M was perfect. I'm 5'3", 130 lbs, 36A, and broad-shouldered. I'm definitely buying the other colors asap!
