I've been a long time fan of SB gym leggings but my last 3 pairs have all started to wear on the inner thighs within a year of buying them. The material bobbles, disintegrates and then holes start.
Admittedly, I do wear them a lot but they seem to be poor quality that have no longevity in them. I do wash them as per the label so I'm not sure what else I could have done.
Maybe my thighs are just a bit chunky 
Has anyone else had this with SB leggings?
Or can anyone recommend better quality ones? Thank you
