I'm from a relatively warm state, so I didn't even know what fleece lined leggings were until a friend suggested them when I told her I was going to Chicago for work.

Feel: These feel SO AMAZING and comfortable! They were just so cozy, I wanted to stay in them forever.  I thought,"WOW... this must be what those "pajama jeans" feel like!!!" All joking aside, I couldn't have asked for more comfortable leggings.

Fit: For reference, I'm 5"3 & 127 lbs.  I got the small mostly because the mediums were sold out and I was in a bit of a time crunch and needed *something* ASAP.  I didn't have any problem with the small size.  The leggings came up to about mid-rise which I expected and prefer for hosiery.  I do have a booty, but didn't have any problems getting it in the leggings.  I read some reviews where having a booty was an issue for some people, but I didn't have that problem for some reason? I don't have a really good explanation for that, but I'm glad these fit me fine including my rear!

Look: I liked that these leggings provided warmth without bulkiness.  They looked like a fuller version of some opaque tights I have.  I would love if these came in a footed-tight form!

Overall, I really liked these and would recommend them.  I've worn them a few times now and haven't had any issues with them.  These have even walked a few miles in downtown Chicago!
