OUR SOCIALS
Move with ease in Sustain Tanks designed for studio sessions, travel, and everyday layering. A clean athletic cut, breathable comfort, and lightweight feel keep you centered on and off the mat. The fabric sits smoothly against skin so you can focus on form, breath, and flow.
A refined silhouette sits smoothly over shorts or joggers and will not ride up during flow. The armholes and neckline are shaped for mobility so you can move freely through warmups, peak poses, and cooldowns. Subtle detailing keeps the look minimal while supporting confident movement.
Lightweight, quick-drying comfort helps regulate temperature from class to commute. Soft against skin and easy to layer, these tanks transition seamlessly from practice to daily wear. The fabric dries quickly after intense sessions so you stay comfortable longer.
Crafted with eco-conscious materials and durable construction, Sustain Tanks hold their shape and color over time. The minimalist aesthetic makes them simple to style across your active wardrobe. Fewer distractions and thoughtful finishes make them a go-to layer every week.

These cuffed yoga pants are great! I liked them so much I ordered two more.. for reference I am 5’9/160 lbs… the small works great for my frame.
These feel so good to the skin. The fit is correct and they look great. Might be my favorite pair of sweats. I bought 7 more pairs and cant wait to receive them!

Totally beautiful great color fits like a glove.
This is my third pair of these shorts in a size S. I really like them. The stretchy soft rib fabric is great for shorts and feels awesome to wear.
I am 6’4” 200 lb with a 31” waist. I often wear a 30w jean (I would wear smaller waist if they came in longer inseams but 30w is usually the cutoff for tall mens jeans). I wear a M in other 4-rth styles, but an S in the rib shorts on the initial advice from the owner, and it works for me. But I will say that these shorts fit nowhere near as long as what’s shown in the 6’1” model pictures. These are an upper thigh, short short on me. Even accounting for the height difference, these are shorter than what you would expect based on the pictures. Maybe because my thighs are thicker?
The quality of these, amazing, it’s like heaven touching your skin. I’m 6’5, about 210, large was a great fit. The company is very receptive and reaches out quickly when I had issues with my package being stolen. I went and purchased two more pairs. Outstanding
I think that ive got them all! These are perfect for the gym, especially because of the longer torso length/fit. I also love the capri pants for workouts when its hot out.
I was skeptical about how exactly I would use these - are they a sweatpant or a going out pant? Turns out they're both! They're more comfy than most lounging pants I've worn, yet can totally be worn as a regular pant. I like using them for yoga; the zipper and buttons don't get in the way too much at all.
They are quite slim, but not as skin-tight as I expected based on the description, and they are quite long. I am 5'11" and 170-175 lb with pretty thick thighs and the medium is perfect. I had to hem off about 3". That being said, I do not have the longest legs for my height, and prefer a shorter inseam. If you are taller or don't mind them hitting a bit below the ankle as in the photos, it won't be an issue.
The only feedback I have would be - please offer these in a shorter inseam, and I would love to see larger back pockets in the future. I don't love the look of small back pockets, but they aren't so noticeable in the black. By the way, same for the short version of these - the length is quite long, and would love a slightly shorter version.
I love your products. This one is great as well, although for me I’d prefer a bit longer in the body. Still love it though —thanks.
These are absolutely outstanding for my hot yoga practice. No uncomfortable bunching. Highly recommend
These are comfortable and cool all rolled into one. Great for kicking it back at home or any casual event. Yoga. Running. There is no limit.
Absolutely love the fit and feel.
These are hands down the most comfortable and attractive shorts I’ve ever owned. I’ve never gotten as many compliments about an article of clothing before (all from women, fwiw). I have these in three different colors but these seem to get the most positive feedback. I’ve worn them to the beach (even swam in them), to the grocery store, to Pilates. Had to get up my nerve to go all white in public (with no underwear) but it was totally rewarding. They’re the best.
