i bought these in preparation for my post-baby body and just comfort in the first several weeks after delivery and these are exactly what i was looking for. they are cute and a little bigger than i thought they would be but they still fit, i ordered a medium. i currently weigh 155, 34 weeks pregnant, 5'4'. material is semi-thick, not thin at all but not something i would rely on for outside winter temps (but still could work, as i plan to do). i came on here to review these because i am looking to get another color now i love them so much. originally i ordered amazons version of jogger pants and those were horrible (too thin for what i wanted) and extremely huge for mediums, so those got returned and im using the credit to buy another pair of these champions.
