THE best legging out there! Not just the all-important "free from toxins"(*SUPER essential) but also so comfy. I don't want to even take them off. And love the combo of comfort with true high-performance.

Love the leggings! I have them in grey and was hoping that the blue would show less sweat. It still does a bit but the peace of mind of not wearing toxic chemicals right next to my skin + the feel and fit is worth it! I will also say that I expected/hoped for the blue to be a bit more lure blue without the purple tint.

Stays in place

Loved the blue color
I worked out and walked in them and they stay where they should.
They’re comfy and soft
I wear a size small in Athleta and Lululemon so I ordered a size S in Aktiiv and the fit is the same.

stunning

Love that these are non toxic, don’t get me wrong, but the color alone is why I bought these ! they are gorgeous and feel so good! Absolutely recommend for any type of workout.

Super surprised!!

I am very picky when it comes to leggings and fabrics! The high rise is perfect and the fabric is super comfy! I am an 6-8 at Lulu and I got an 8 and there was some extra fabric around the knees but I think I wpuld prefer that over the extra compression a 6 might give me. Definitely my new favorites though 😍

Love them

There look and feel great, better than most leggings in my opinion. I love that they are made workout toxic chemicals and are plant based! I can’t wait for more colors!

Simply stunning leggings!!!

As a lifetime, exerciser, I’ve put on a lot of different outfits that have been designed to keep up with me. These are absolutely stunning! The softest by far, the most comfortable, the perfect weight, not too heavy to impede, a vigorous yoga, practice, or too late to wear in New England winter under a pea coat. They’re absolutely perfectly made. I love the sewn inseam that provides a little bit more stretch and comfort and peace of mind. Truly outstanding. Five stars all day long. Great work.

So comfortable

Love the fit and the feel of these leggings! They were comfortable, not ridiculously compressive (I felt like it was really my body moving around and not a body encased in a rubber band). The color was so nice, a pleasant pop of brightness in my activewear wardrobe.

Obsessed

These are somehow both comfortable AND make me look snatched and strong, no restrictive waistband. And they're so so soft and don't seem to hold the smell of sweat, so they can go awhile between washings, which I love.

Buttery soft, super cute, and squat proof

I love these leggings! They are full coverage, medium fabric weight, warm when you want them to be and breathable when you don’t. They’re almost creamy/marshmallowy in texture.

I’m tall, 5’9”, 140lbs and ordered the S in leggings. They’re snug and fitted like I like them, but I could easily slide into a M for a more comfy fit.

They are also a super cute set with the matching bra! I got both the bra and leggings in the blue color and it’s a vibrant, rich, blue.

Lulu Who?

These leggings are like butter! They are incredibly soft and comfortable, providing a smooth feel against your skin. Not only do they feel amazing, they are also supportive and form-fitting. The Proterra leggings are my new favorite! In fact, they are so good that they surpass the comfort and fit of Lululemon leggings!

The Hype is REAL! 🌱 🌎

These leggings are soooo so buttery soft! They are breathable, the compression is perfect, they pass the squat test, and BONUS, they are good for the planet! If you are thinking about getting a pair, do it! You won’t be disappointed. Even the compostable mailer!

I have been a loyal lulu / ALO customer for as long as I can remember, and these are BETTER. I am a spin instructor and trust me when I say I use and abuse my workout clothing. The leggings pass the bend over test, stay in place during the entirety of my workout, and the fit is superb.

I will be talking to all of my clients about these perfect non-toxic leggings! Patiently waiting for my size to come back in stock in black :)

These are my favorite non-toxic leggings - sweat-wicking and the fit is great!

I have multiple pairs of these leggings. They are so soft. The fit is amazing (I ordered my normal pant size). And, they do not show sweat. 10/10. It is so nice to have a healthier alternative to the big active wear brands that are poisoning us!

The best non toxic leggings that don’t suck! These feel like my favorite synthetic leggings without the toxins. I can squat and not show my undies. They stay where they should! I’ve bought 3 pairs already.

Love these! They fit and feel so great. A lot like lululemon align. I wear 4 in Lulu align and bought a 6 here. I was between sizes. I’m sure I could have done a 4 as well. Looking forward to more colors- navy, a blued grey, more neutrals!

I really like the leggings. They fit great and are not see through. I'm going to order another color.
