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)

Strap detail is nice

Nice back, zero shape, zero support. Good for Yoga

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!
