I bought both the normal travel knickers and the firming travel knickers. While the standard knickers are very comfortable with good coverage and plenty of stretch, the firming knickers do not stretch very much at all and seem very tall and narrow compared to the same size in the standard model. This meant that they dug in at the waist and rolled over because there was so much excess material. By the end of the day they had rolled up so much that it pulled the leg holes up and out of shape. Looked horrible. I didn't really want firming knickers and only bought them because there was a better selection of colours in my size. Not for me and I should have sent them back.
