These pants are amazing. They have great flexibility/stretch, allowing for a great range of movement. They are also light weight, so they are good for even warm weather. It comes with side pockets, a rarity in most leggings but much appreciated. Awesome for holding phone or keys. They are made of a smooth low friction fabric that is great for running. There is also no front middle seam to avoid the embarrassing camel toe.
The biggest downside has to be its price. These are pretty expensive, around $120 (but that’s Lulu for you). They don’t make the longer ones anymore and have added a drawstring so that could help with the squat test. The version I got did not hold up to the squat test. Needed to constantly pull up pants. Because of the low friction fabric not so fun when lifting. Having to readjust when doing leg extensions or any seated lifting exercise. I kept sliding around in the seat.
Overall if it fits your budget, I highly recommend these pants if you are looking for a new pair for running or general exercise, but avoid for lifting.
