Buy these immediately!!!!!
Size: 3X, Color: (001) Black / / White
I was so happy to find a name brand pair of sweatpants in my size. When I ordered them, I thought I shouldn’t have wasted my money as I would probably have to return them. I was SO IMPRESSED!!! I tried them on and they fit like a glove. A little room to spare but I was so happy to have a nice pair of sweatpants. They are so comfy and warm. I got them on sale and they were a steal. I would have paid so much more buying them online or at a store. Thank you for having bigger sizes and clothes that are true to size. I love the way they look on me and fit!!! My new favorite pair of sweatpants and I even bought another pair. I now have two pairs in black. The sweatpants kept me warm on a cold day outside and just comfy enough without being too warm inside. The weight of the sweatpants is perfect.

Delayed delivery otherwise ok
Size: Large, Color: (025) Castlerock Light Heather / / White
Seems of good quality so far. Very comfortable. Fits well and doesn't look baggy. Took away a star because it was delivered over a month after purchase

Warm and cozy for winter
Size: X-Small, Color: Black (002)/White
I. Love. These. Pants.
I have them in three colors and I feel like I live in them during these midwest winters. They are cozy and comfy for around the house, but are totally cute enough to wear out and don't feel like typical sweat pants or pajamas like some joggers can. They are warm and snuggly inside, which I like, and have held up really well after several washes. I would say they run a little small, so consider sizing up unless you like a snugger fit. I am usually between an XS and Small and went with XS on my orders. They are slightly loose but not baggy. They also are not super long, mine hit me near the top of my ankle and I'm 5'4". It doesn't bother me, but I do find myself pulling them down at the ankle when I get out of the car or stand up from the couch, because they just seem a little high. For a comfy, warm, casual but stylish athletic type winter pant (exactly what I was after)... this is it.

They fit perfect and are super comfy
Size: Large, Color: (001) Black / / White
Very soft and comfy! They are not the thickest to wear during a brutal winter, but they are warm. These are true to size (as recommended by my Amazon account). I loved these pants so much that I got me two more. They look great!

High quality, good fit
Size: XX-Large, Color: (001) Black / / White
These fit perfectly, not super baggy and lose but definitely not tight. I have larger knees so sometimes tapered legs are too tight on my knees but these are perfect. Waistband is perfect. Thickness is not too hot or too cold. Soft and breathable.
