Edit: I liked these enough in blue to order the gray which turn out to be shorter and narrower than the blue. These still fit me in gray but are significantly narrower and shorter than the blue--an inch to an inch and a half.

5' 6", 140 lb. Female - got a medium. More loose in the waist than would be a perfect fit for me, but the tie fixes that issue. Not tight in the legs, but also not too baggy. The length is great. If they shrink a bit over time there is room for that, but not noticeably long now. Great fabric and construction. I consider this to be a midweight fabric which is as heavy as I would want in sweats. I wanted a comfortable, not too tight pair of sweats, and these are just about perfect.

Look closely at picture. Great stylish sweat pants for the right person, just not for a 69 year old guy who struggles to remove them with such a tight ankle fit. My two other gripes: side pockets way too shallow to trust holding anything when sitting, and a crotch that stops before you can pull them all the way up to a comfortable position. Younger generation would call them low riders and look sexy.

I'm 6'2 139 pounds (yea I'm skinny)

For whatever reason I ordered an XL. They were way too big on me, I am returning for a Large. Hopefully they will fit me.

But the pants were premium quality, I could easily see paying like $50 for these. Great packaging and everything. Very soft and comfy! Also very stylish, you could bum around the house with these on. At the same time you can go out in these, and look super good.

There are a little stretchy so even if you get a smaller size you will probably be fine.

Over all great quality! You can tell they are durable and will last for a long time! Stitching and buttons are great, definitely would recommend these.

I'm 6' about 185lbs and the medium fit, almost on the snug side but a large would have been too loose. they are very very soft but the knit fabric doesn't have much stretch which makes it less comfortable then they could be. it's too bad because these are probably the softest joggers I've got but have the least amount of stretch almost like a woven fabric which feels restricted. for the price they pretty nice, the color grey matches the photo.

I was little deterred when they didn't have a small size, but I liked the look, so I went ahead and ordered a medium. I was pleasantly surprised with the outcome. The waist is a little big, so I have to tie the strings a little tighter, but the length was perfect. I like how it hugs my calves lightly, and the cuff at the bottom stays in place. For reference, I am 5'8'", and about 120 pounds. I don't have a reference for the small, but the medium has the perfect amount of space around the mid-thigh. In comparison to track pants similar to Adidas' (I went with a small for a more true to size fit with those), I find these to be more lounge pants due to the overall look and feel.

I expect the price on these to increase and I've already bought 5 pairs to hand out for Christmas and two pairs for myself.
I'm a 5'3" female weighing 160lbs and I went for the medium. Could've gone for the small but I like the big fit. The drawstring is generous enough and stays put if you want to adjust the fit. They are perfect and I am tempted on buying more, especially with the price. I absolutely recommend this product.

These sweatpants may be only $20, but they look and feel even better than ones two times their size. I am 5'5 and 115 and got a size S. They aren't fitted as expected but aren't too baggy or shapeless. In fact, the silhouette looks super cool even though the pants aren't tight. The stitching, fabric, and even the tie are all high quality. These sweatpants are comfortable and extremely warm. The drawstring is slightly long, which is great because the string does not pull out in the wash or dryer like other sweatpants with shorter strings. Shipping was super fast ad well. Overall, if you are thinking about buying these, stop immediately and just get them. You won't regret it!

Otherwise this garment is great, nice fabric, fits as expected, very comfortable. But, if you are one of those people who puts things in your pockets sometimes buy something else. These pockets are so small and with an odd curved shape so that everything always falls out if you sit down.

After the second time these ejected my cell phone onto a cement floor I put them in the back of my closet where they can hide in shame.

I bought some Southpole brand sweatpants later that are nearly identical visually, but the pockets are usable and they fit better.
