Tri-Color Stretch Eco-Track & Yoga Sweat Pant (Sand w/Chocolate & Black)

Great Fit

I mainly wear a small when wearing 4-rth clothing. However, I wanted a more loose and casual fit so I got these in a medium for house lounging…. I love them, they are super comfortable and very well made.

Eco-Track & Yoga Sweat Pant (Cinnabar Red w/Grey)

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?

Fusion Yoga Short (Heather Grey)

Just amazing

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

Long Cuffed Jogger & Yoga Sweat Pants (Black)

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.

The Perfect Tank (Aqua Blue)

Lounging + Going out in one pant!

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.
