Reviews
Thank you
"I always thought leggings always just fell down as the day went on and pulling them up all day at my thighs was normal… Guess what it’s NOT! These are the best I have ever owned and that’s a huge call for me! I only have the straight leg leggings and I would love more colour options, Navy, Black, Olive and true choc brown would be amazing! Keep me warm (first time ever) and cool! I can’t fault them at all!!!"
Unbelievable Quality
"Ngl I’m not sure what I thought the material would be like but the fabric is actually of an unbelievable quality. They feel warm when it’s cool, cool when it’s warm and just literally look amazing on (so supportive). Will defs be buying from estroni when I need to replace my workout wear in the future."
My new fav pants
"I can’t speak more highly of these pants, they feel supportive but soft and comfortable and the quality is incredible. Genuinely living in them!!"
These pants are amazing!
"They feel so nice and supportive! They have a texture that I could stay in all day. I also don’t get that usual activewear smell at the end of day. So nice! Also flattering cut. Definitely invest in these!"
Incredible pants
"I have most of the Estroni range, I really love the brand and find it comfortable and well fitting. Naturally I brought these on preorder, I had low expectations because trackpants are hard to do well. However, these are literally the best trackpants. Beautiful fit and very comfortable. The brown is a nice colour, normally I don’t do brown trackpants, but these are really nice. My only complaint is that I need them in more colours."
Gorgeous Pants
"Love these pants great fit and great length."
Stunning
"Absolutely love these leggings! They are a beautiful fabric and mould so well to my shape! The only thing I'd love different is a bit of extra length, as I found after a few wears and when they had worn in to my shape, they did rise up a little. But I also have other pants with extra length, so I'm not used to them sitting just above my shoes. Other than this, I LOVE them!"
So soft and flattering!
"I love these leggings, they are such a soft material, super comfortable. They are a really great fit."
Worth the hype
"The most compressive and beautiful fabric. The colour is perfection would highly recommend. I am usually between a 10/12 but went with the 10 and it’s perfect"
Absolutely love
"I love the cut that it doesn’t have a seam at the front and how it curves at the back. The fabric is as always amazing and the fit is perfection. I love this brand, I love their product!"
My new favourite leggings
"Love these so much - great quality and comfortable with a really nice feel to them. Will be buying again."
Favourite Staple
"I have worn these for so many days in a row AHAHA they are so comfy the fabric is so soft. I love the fit, the colour! I can style these in so many ways! literally my new fav leggings! And my butt looks so good in them ! Slay"
CHEF'S KISS
"These pants are super flattering and equally comfortable. Love the flow of the straight leg without being too wide and the waistband feels secure without being restrictive. I can see these becoming my everyday comfy pants"
Activewear wardrobe staple
"First purchase with Estroni and I couldn’t be happier. These just arrived this morning, I put them on straight away and haven’t taken them off. The waist band is fitted and supportive but not tight, the fit is better than I could have hoped - I’m more of a curvy 10 and these are really flattering. They’re also a perfect length, they almost hit the ground."
