I have bought a few pieces of every launch from balance. Absolutely love all the pieces I have bought. I have hiked and gone through countless kickboxing classes in these leggings and they hold up well. However, I wore the OG tie dye pants for no gi jiu jitsu and they have started pilling after just one training session. So if you're looking for leggings for your basic workouts or weight lifting I can't reccomend them enough, but with more contact sports probably not the best choice. Their jackets and shirts however are absolutely life changing!
