Best BAM leggings/pants

[1potato]

I've been searching high and low for ethical yoga pants/leggings and getting myself super confused over material, length and waist height. I think I have settled on BAM. Can anyone recommend any of their specific lines? I'm around 5ft 3 and I'm size 12ish 4 months post natal. Thanks!

Ive got the Adventure leggings. They're quite thick but I use them for hiking. The waist is quite high and holds everything in.
After a 26 mile hike they were as good as new and didn't rub anywhere. They don't go see through around the butt which is useful.
I'm 5ft 2 and and think that the 7/8 length would have been better on me as they are quite long.
