Good fit, very see through

They fit and look great, but be warned!! They are very see through, make sure you’ve got some light colored underwear!

100% cotton, but still easy care
Size: Large, Color: Khaki 2
I bought 5 of these pants and I am glad that I did. The elastic waists are easy pull up and down (especially for the mobility handicapped like me). They wash and dry nicely - I don't bother ironing them. They are nice, light summer pants (good year round in FL).

Sizing is off.
Size: Small, Color: 3 Black
Much shorter than expected. Poor fit in the legs as well, at least for me. I’d say they are a couple inches shorter than the size chart. I expected them to be short, but not waiting for a flood. Material was nice but overall not a good fit for me.

Sensory Friendly
Size: X-Large, Color: Medium Grey
Sensory friendly. My son and I are both Autistic and finding comfortable clothing is challenging... Sweats and tshirts are our go to. These pants are an upgrade to our wardrobe- very comfortable and great for lounging at home or dressing them up with a nice shirt to go out for the day. I bought these for my son to try and he loved them! They were a little too tight, (winter weight) so I ordered two more in a bigger size. I however kept these because I love them too. The fabric is a nice and breathable with a slight give. I wore them outside yesterday in the hot AZ heat and I was comfortable and in the evening it cooled down with a rainstorm and I was happy I had these pants on. The pockets are amazing! Don’t get me started on pocket size vs phone size. My iPhone sits way deep in the front pocket and hits about thigh level… my iPhone isn’t going to fall out and that’s good peace of mind knowing my investment is safe. Overall my son and I are very happy with our new pants.
