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.

A cross-back design provides unrivalled freedom of movement without sacrificing the support. Feel your best whether you're flowing through yoga, pulsing in barre, or picking up the pace in cardio.

Crafted for all day freshness. Breathable and naturally cool to the touch, BioFlex fabric provides instant relief when your workout heats up.

No more sagging, threadbare activewear. Naturally durable fabric means this bra holds its shape, softness, and stretch wash after wash.

Worth noting it does run a little large

Comfy, supportive

Looks and feels good. I am usually an M (bust 14B) but I got an L as the biofeed seems to run small. The L fits me well. I like the red colour too.

Comfortable

Overall it's comfortable. A little loose around the front. I've a large ribcage and small breasts and it's not always easy finding bras that accommodate such. It fits well around the ribcage but the cups are slightly too roomy for me.

So disappointing

I love everything Paire, I own 1 million pairs of socks and undies, and so was very excited to try their activewear. The leggings are just superb, firm, comfy, a dream.

Not so much this bra. For a start it needs waaaaaay more fabric so that it can provide some coverage to the DDs amongst us. I realise this is a medium support bra but it needs firmer straps and more back/side/front coverage.

Only suitable for A-B cups.

Squeaking straps

Really comfy and supportive - went back and bought a second one. Only issue is the straps squeak really audibly when moving around. Doesn’t scratch or cause any discomfort but you do hear the loud squeaks. Maybe consider a different material for the straps? 🤔

Soft, but needs more size ranges

I want to love this bra, but I really need it to be smaller around the ribcage and larger for my actual breasts.

Big bust size up

I’m usually a 12 F cup and purchased size L. This was a bit tight I’d recommend sizing up if you have larger bust.

Was worth a try

This bra is pretty comfortable. It fits me well but I’d like the cup coverage to be a bit more. It certainly reduces my under cup sweating which makes it worth it.

Bioflex medium support bra

I love this bra so much I am about to order another. I wish they had a beige version too. It is a very light material that dries quickly, yet supports well.
