Cannot say enough good things about these Zella leggings! I wear them primarily in the fall/winter with tall riding boots and a tunic or oversized sweater. They are just thick enough to provide a bit of warmth - without making me feel too hot. The material is very durable, I bought my first two pairs winter of 2012 and they are still in great shape! These can also be used for exercise purposes as well (running, yoga, etc.) They run true to size and don't bunch at the ankle which I love. These are an even better version of Lululemon's $90.00 leggings! ; )
I just purchased my very first Zella Leggings and I am completely amazed at the material, fit, and comfort. These are by far the best leggings I've owned. So versatile and can't wait to wear them with sweaters and boots in the winter. Will definitely buy more.
