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.

Best sports bra I’ve found

I’ve got an Ironman coming up in July, and I’ve been really struggling to find a bra built for big boobs that I can swim in. I LOVE this bra, and I’ve now ordered every color in 3x. I’ve worn it as a regular daily bra, I’ve worn it hiking, running, and walking, and I’ve worn it cycling. This weekend, if the lake water is warm enough, I plan to try it out swimming (along with the Janji shorts I’m considering wearing for the race too!)

Blew away my expectations!

I ordered this bra hoping that it would work my larger cup size and it absolutely did. The back pocket for the phone is awesome, too. I usually wear either 32D or 32DD bra size and this bra holds me in and feels secure while also being lightweight and comfortable. I ordered a small. I’ll be ordering more bc I can’t stop wearing the one I have. So far I’ve gone up to around 6-7 miles in it but cannot see it being a problem once I get into marathon training.

Love this bra!

I use this for long runs, indoor bike workouts, reformer pilates. I like that I feel secure and can feel a little sexy without showing any cleavage. I also like that it doesn’t feel constricting and yet keeps everything in place while I run. It’s a great bra!

One Sports Bra Quiver!

I am a 34DD and wear a medium for a snug fit (but not restrictive) which is so comfortable for long runs or walks that turn into outings while not feeling tight around my ribcage! I love this bra and will be ordering in all 3 colors since I only snagged the bright greeny-yellow last year!

I won't race without this bra!!

Ever since I got my first Ascend Sports Bra for CIM 2022 I haven't raced without one. The back pocket is PERFECTION, especially while you're racing and you want to have your phone on you but doesn't need to be fully accessible the whole time.

I like the higher-rise neck line to protect from the sun a bit more, and the thicker straps don't chafe.

It is a bit hard to get your phone in & out while actively running, so it takes some practice and I highly recommend testing while training so you know what angle to reach for.

I will also run with just this sports bra and without a shirt over on a hot day and I still find that it provides enough coverage so that time comfy and still comfortable.

I take the pad inserts out immediately, so can't speak to those. I'm a 36B in a regular bra and have always run in the Medium without issue.

The most comfortable bra ever

Not a super busty runner and never worried about support. Until I started training for an ultra. Smaller chest or not 5 hours of running will get things sore. This bra is nicely supportive without being too tight for comfort. It hasn't chaffed even running in damp conditions. I will buy one in each color I love it so much. Also wore it through a 12 hour shift at work and it was fantastic for anyone else in healthcare.

My go to sports bra

This is by far my favorite sports bra. It is supportive and prevents chaffing without feeling constricting. The phone pocket is handy when I don't want to bring my waistbelt.

Supporting supportive bras

Running is hard enough but, as someone who usually fits a 34DDD bra, running can be a little harder without the right gear. This is the third ascend sports bra I have bought and I will keep buying it until all my old bras are replaced. The material is very comfortable, the straps do not dig into my shoulders, and the band doesn’t make it harder to breath. So far, my longest run in this bra was 12 miles, I didn’t have to adjust it (or my boobs) once. Remarkable.

Favorite

I own two of the W's Ascend sports bras and they are the favorites in my rotation. For me I can easily put my phone in or take out of the pocket in the back. I am a marathon runner and have had no issues with chafing on the long runs. For size reference I am 5'7", 135 - 140 lbs, a 34 B and the small fits me great.
