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.

Solid bra- runs small

Really nice material and fit, delivers on seamless promise. Removable cups are always annoying in a sports bra but that wasn't a dealbreaker for this particular bra given it's quality. I am smaller chested and often struggle with cup shape, not this time. The band ran small for me but Paire is so cool with their size exchanges, I've never had an easier experience requesting a new size (bought an XS which was very small and sized up to a S which was a little tight but works as I assume it will loosen with use)

So close to perfect

LOVE but cup pads need to be changed, they are thick and uneven. Thought the bra looked weird but swapped out the pads for thinner and smoother ones and it looks much more flattering and feels less top heavy. The brand mission and quality makes up for the trouble.

I think its close to perfect, but I think the cups look a bit too stark and obvious, maybe? Its not the end of the world as I can remove them but it’s almost like they need another layer of fabric in front of them so they’re less obvious. Otherwise, this is pretty much the perfect sports bra for itty bitties

Disappointed

I purchased 2 of these bras looking for a comfy sports bra. I’ve found them too big and of below average quality - the seam under tbd arm is rough and rubs. I used tvd online measuring tool to order but might have been better off with size down.

FANTASTIC light support bra

I have looked for years for a sports bra that is as comfortable as the original Lululemon free to be bra (which they no longer make). This is absolutely perfect! Super comfortable, fits well, stays in place and most importantly (for me) the band is soft and doesn't dig in. The fact that it's more sustainably made is the icing on the cake!
The fabric is soft and the brown colour is gorgeous (I also bought the black). If you're looking for a super comfortable light support sports bra, you've found it!

comfortable soft bra

This bra feels nice on. It does not offer a high level of support. If I pull the back together it is better. Stays fresh and does not get smelly after sweating.

didn't realise there was no clasp at the back, photo not that clear, and I don't like having to put over my head
more than 'light support'

I don’t love it :(

Though it’s a light support bra, I expected a bit more than what it’s giving me. I don’t consider my bust large at all (between A and B cups). However, I feel the under bust support is lacking even in my cup size. I can’t imagine it’ll support any bust size. The hook at the back to crisscross the bra strap doesn’t stay on at all. I have to get someone else to hook it for me. I think a re-design is necessary.

Very close to perfect bra

Very comfortable fabric, fits well, moisture wicking and ALMOST perfect.
Usually for me, bras are either too tight around my ribcage or too large across my chest so it ends up in my armpits. This one fits well in both respects, however there is a strange 'squeakiness' and slight scratchiness from the straps.
Would def consider buying again.

BioFlex™ Light Support Bra

Absolutely the most comfortable bra I’ve worn in a long time. I loathe underwire! Makes my boobs perkier too.

Supportive and comfortable but it’s a very tight stretch to put it on, so much that I can hear the stitching break. Hasn’t come apart yet so fingers crossed it lives a long life!

So comfy and supportive

Never really had a white sports bra until now! Material is so soft and fits me really well.
