I bought the summit leggings as weekend wear for the inclusion of functional pockets. I have worn the axis leggings for 2 years nearly daily under dresses at work, except for summers when I wear the Frankie. RE: the summit leggings - I love having an easy pocket for my phone while chasing my kids around. The thickness is excellent and comparable to axis. However, I noticed the summit leggings appear to have a different waistband elastic from axis or Frankie, very thick, which held a strange wavy shape after taking them off the first time (waist band didn’t lay flat when I laid them on the bed). So far when wearing them I don’t notice it. I’m curious how the waistband will be after washing.
