EDIT: NEW MODEL IS ON A NEW LEVEL NEW Model Leggings: The first leggings I brought from Aztec were the old model, they contacted after my review and sent me a complimentary pair of their new model leggings. Thank you Aztec!!! I have tested them in every way and 100% approve of this new model. These leggings are SO MUCH better than the previous model. They are much better quality, the stitching doesn't rip, and they are reinforced at the bottom so they don't rip when you pull them over your heels. The waistband is thick, comfortable and sewn in, there's no way it can flip since it is actually a part of the construction the legging. These are slightly thicker than the old model (good thing!), so they don't show any cellulite you may or may not have (just saying, I'm thin but the old ones were so thin that it still showed cellulite in certain positions). They are very comfortable, and the styling is excellent. The pockets are so much better too!! Deep enough that your phone/etc. will stay secure in any type of riding. (jumping, equitation, liberty, endurance, trails, little races here and there, I do a bit of everything) In the old pair, they were too shallow and slippery that my phone would just fly out- not the case in these new ones! This new model is built to last. I can ride in my bareback and feel just as secure as riding in my Adidas soccer pants; I notice no difference. The "discreet" gripping system is exactly that: discreet. I don't notice it help but maybe it does. That would be my only critique with these new leggings: please make it less discreet and add more grippies! Sorry, but in this one instance, they cannot compete with my Kerrit Ice-Fil tech leggings. Yet, those have full-cover grip, while these do not. Aztec, for your next model, make a full-seat grip legging! :-) I will definitely buy. I think the new fabric is really what keeps me in place. No where near as slippery. These leggings are thicker than my Kerrits and not quite as stretchy (but that's not a negative) and better styling. These Aztec leggings feel higher-class? / more professional in a way. They feel nicer and more sophisticated. But they can still take a beating in whatever you do. I don't wear these in my slippery Australian saddle (it has no rough outs) but I have no problem wearing them in my western rough seat, suede-type bareback pad, or Thorowgood english saddle (synthetic with suede-like knee roughs). They look great, feel great, and are totally functional. I 100% recommend. Thank you Aztec for reinventing your leggings!!!!
