Love the fabric, and cut of the pants. Not see thru at all, and the way the pant is constructed, gives a lot of comfortable control & support. Fabric also has good wear, I've had 2 pair that I wear every week for working out, and the fabric has really held up well with many washes.
This is my third pair of the Zella balance pants. They are perfect for running errands around town when you don't feel like wearing jeans and they are great for lounging around the house too. I would imagine they would be good for working out as well :)
