Reviews
Très joli coupe et couleur
"Taille très bien et bon maintien"
Love the color ♥️
"Love the quality and was able to use it in my heated workout class! So good to not sweat in plastic and it dry so quickly! I should had sized up because it’s a little tight but still feel comfortable. I’ll order more but in size 6:"
My favourite bra ever
"Putting this bra on for the first time was a truly cosmic experience. I’m usually a size 8/10 and bra size 12B. I bought a size 10 and it’s snug but perfect for support. Could not be happier :)"
Amazing fabric and fit
"The fabric is very soft and durable, padding is comfortable and it is true to size. Will definitely buy more!"
Very comfortable
"A great fit I'm a 12D and went the medium. Definitely only suited to low impact for bigger bust's but I still think its fabulous"
LOVE THIS CROP
"Estroni's peices are some of the best natural fibre activewear I have tried. I am so impressed with the fabric quality, it feels tight fitting yet soft to touch, it is thick yet breathable. The styles of the crop is also extemely flattering. I really really love this piece!"
Comfy
"Comfy fits to size feels refreshing to wear something that is good for your body"
Perfect sports bra/bralette
"I will be wearing this everyday, healthy on the boobs and super comfortable."
Absolutely recommend this sports bra
"I love the look and feel of this sports bra. The indigo colour is amazing. Will definitely be purchasing again."
So flattering!
"I love this sports bra so much! Especially the criss cross straps and the vibrant red. It is super supportive and doesn’t dig in. Sits beautifully on the body."
Love it!
"Such a nice bra to be sweating in. Love the red colour it is gorgeous, and supportive. Also if just feels so comfortable soft and breathable for your skin."
look after the girls 🍒 and your pits chicks!! ❤️
"Obsessed! After having cancer in nearby lymph nodes next to where my bras sit, I have been looking everywhere for natural fibre sports bras for sweating in. I initially ordered from PACT but much prefer the fit of these merino wool ones :)"
Super supportive
"Super supportive bra, beautiful colour, perfect for all kinds of movement, will definitely be purchasing again!"
No sweat marks and natural fibre!
"Beautiful material, no change in quality wash after wash. No sweat marks, hot Pilates proof!!"
100% recommended
"Universally flattering fit including wide, thick padding. Most padding in sports bras is too narrow, thin and triangular - this really makes a difference! It fits my small chest well and seems to have lots of give for larger busts. I ordered black and it is a true black."
Just received and very happy!
"I’ve tried a few different mostly cotton blend crops for exercise but this merino fabric is SO much better. It feels firmer in fit and therefore more supportive and the fabric is still super soft. I also avoid cross and race back styles because I find the straps dig in and annoy me but because of the natural fabric these ones are comfy as. If these wash and wear well then I will never go back to anything else!"
The best yet !!!
"I have fallen in love with this sports bra ! Very comfortable and supportive. The merino fabric is soft on the skin, breathable, and regulates temperature well during exercise. A great quality sports bra that feels comfortable to wear all day."
AMAZING!
"I'm beyond happy with the set that I got! I've been slowly getting rid of all my synthetic clothing, and finding activewear is the hardest part, especially with a nice fit and feel. This set absolutely exceeded my expectations, the fit is cute as, the merino is soft but sturdy, the colour is amazing! Absolutely love what you guys are doing, I'm telling everyone!"
Highly recommend
"Very, very happy with my crossback sports bra. I've worn it almost constantly since it arrived. I've found it comfortable, supportive, and breathable. I was worried it would be itchy but it has been fine. My cleavage area is where I sweat the most and i love knowing I have all the properties of merino wool to protect me from feeling wet and stinky. I got the red colour, and it looks great. I foresee myself buying another one of these in the future."
LOVE!!!
"Absolutely love my tank and bike shorts, they feel and fit so nice on the skin and it makes me feel so snatched but also good to have such natural fabric against my skin while I’m training, sweating or just out and about! Thank you x"
Super duper comfy
"I love wearing this as an everyday bra actually and it’s great for when I decide last minute to do some exercise - I don’t have to change bras! 😍 would love to purchase in more colours"
Super comfy and flattering
"Finally decided to bite the bullet, was hesitant to pay this amount for a sports bra but it is actually so much more comfortable than my polyester pieces and even better knowing my skin is not absorbing microplastics."
Breathable and comfortable!
"These bras are beautiful, they are so comfortable, breathable and flattering"
Love the set
"Obsessed with the feel and cut! We’re in the middle of summer now and the wool feels amazing, light and soft!"
I love this sports bra!
"Love, love, love! The cut is so flattering! It comes down the perfect amount where you can still do downward facing dog without having to readjust. It’s super comfortable and I’m able to wear it all day as a 12D (wearing size M). I literally can’t fault this top 💕"
Obsessed with this top!
"Obsessed with this top!! As someone who only wears natural fibre activewear, this top is perfect. I love the removable pads and the material is super soft."
Perfect for Summer
"Has been amazing for the Summer heat!! This has been keeping me cool rather than sticky and sweaty that I usually am at this time of year. Thank you!!!"
Super comfy and great fit
"Love this bra! it’s so comfy and the merino material feels amazing and super soft. The cut and colour goes with everything - I’ll be wearing this all the time to the gym, yoga and coffee ☀️"
Feels so soft and organic
"Such a flattering fit, comfy on the body - doesn't dig in anywhere yet feels supportive. The merino wool feels really soft and somehow organic on the skin. I can see myself wearing merino instead of polyester in future."
