Product Features

BioFlex™ bends the rules of conventional activewear. Made from 50% recycled corn stalks, our bio-based material is created through an innovative process in which starch glucose is extracted from straw and regenerated into a nylon fibre.

The result? A durable fabric that’s lighter than air and soft as butter. Superior breathability and four-way stretch for perfecting your crow pose. A skin-hugging fit that’s more supportive than the women’s bathroom. We guarantee you’ll be reaching for these pieces even on your rest days.

Go from your pilates class, to the office, to after work drinks without having to change in the bathroom first. Designed for all-day (and all-night) comfort, BioFlex™ keeps you feeling your best no matter what’s on your schedule.

A timeless and stylish staple that complements anything in your wardrobe. Flattering, intentional design that follows and enhances the body’s contours. Feels as good as it looks.

Forget sagging fabric or feeling restricted by your activewear. BioFlex fits as if tailor-made for your body. Enjoy enhanced flexibility and freedom of movement whether you’re pulsing, planking or powering through your 9-5.

Straps too long

Really wanted to love this top, material is lovely. I originally ordered a small, but returned it for an xsmall hoping that the straps would be more secure - but they are really loose and long! It means the top doesn’t hold me in, with the top falling down around my boobs, super uncomfortable when exercising.
Never experienced that with clothing before so I think this is just a bit of a design flaw.

Great sports crop!

Supportive and comfortable. The racer back clip is easy to use and creates a flattering look on the black.

Fit is not quite right

Tried an M initially and was a bit big in the bust area so sized down to S, but although the overall fit was okay, the front gapes a little bit (might be because of a small bust).

I noticed this issue with the other tank top too, the designs seem to be for girls with larger busts, which is a shame because everything else fits well and the fabric is lovely!

Great fabric, perfect fit after a size down

I really enjoy this tank. I wear it for pilates, climbing, hiking, and running. The fabric feels nice and high quality. It stays in place well without feeling like I’m squeezed. I’m usually a medium (171cm, 69kg) but that size was too gappy for my chest (I’m about a 12B) and instead the small fits great.

Perfect for sloping shoulders

Beautiful comfy bra that doesn’t slip off my shoulders. Wonderful to have found an undergarment I don’t have to hoick back on my shoulders all the time.

I bought a few things from this range, but this top is probably my favourite. Feels buttery soft and gives a surprising amount of support for an inbuilt bra. I’ve used it for HIIT workouts just fine. It’s cropped, but only to about the height of the leggings and shorts, so good for those like me that don’t really want a bare midriff. I’m a 12B in bras and the medium is a perfect fit.

Versatile activewear

So impressed with the quality and comfort this tank gives! I love how it hugs my body and it’s super lightweight and can be used not only for workouts but for everyday wear. Highly recommend!

I was never a big fan of activewear with strappy tops - with other products the straps would fall off my shoulders and feel unsupportive or would be too tight to the points that I couldn't move freely. But with this top I get the perfect amount of support and comfort! It was really amazing to put it on and feel so secure. The fabric is also incredibly soft and moisture-wicking. Highly recommend

the perfect basic tank

The new BioFlex material is truly so amazing!! I don’t workout much so I bought this top for everyday wear and I have been wearing it out and about. Its so easy to style and it has replaced my usual basic black tank, love that it has a crisscross detail at the back 🤩🤩
