These are absolutely outstanding for my hot yoga practice. No uncomfortable bunching. Highly recommend
Well lets see, I have 5 pairs of these and many other shorts and pants from 4rth. My all time favorite clothing. Comfy, durable, fits amazing and inspires confidence, (form fitting without revealing). If I had to do yoga without 4rth clothing I'd be lost!
I absolutely love these shorts, bought 3 pairs already and will certainly get more!
I took a break from my workouts in these cuffed men’s yoga pants but I am glad to be back. They fit great and hold their form through intense heated vinyasa practices. Thank you, Doug and Cesar!
Great fit. Love color. Very comfortable.
Fits great! Very stylish and bought a 2nd pair in another color. True to size. Very well made. May order one in every color!!
Been using these for years and have several pairs. Very comfortable and great for bendy movements like squats
These are the best fitting pants on the market.
The customer service is solid. High quality. Great value.
These feel great to wear, I love how soft and well made they are. Theses will last me another 10 years like my last pair.
Great products! Have bought multiple pairs of their pants and tanks. It's nearly impossible to find good yoga clothes for men/masc identifying people, and 4-rth is one of the best out there. Highly recommend.
4-RTH is the best most eco friendly , good for your body and feels so good on ! Best for yoga , gym and all around one of the best quality ECO products on the market ! Thanks for keeping us sexy , fit and comfortable:) mahalo from Hawai’i!!
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.
Excellent look and size!
