I love that it has pockets, is so soft and stretchy, ready to pull-on.
Perhaps because of the stretchiness, and the fabric, they're more for casual wear.
There is a sort of light fuzz to the fabric, which worries me a little that it might start pilling after a few washes, and this fuzz adds to the casual jogger/trackpants look.
Buying it on sale, means it doesn't faze me too much, but it probably means the darker colours may not be suitable. Will have to see.
