I have lots of Lululemon scubas in my house, between 2 teenage daughters and myself. But I always worry about damaging them because they are so expensive! A while back I came across this one at Costco, looks just like a scuba for a fraction of the price. It's well made and fits well. This medium fits like medium/Large scuba. Not like lululemon in the hardware details or the more flattering fit, but I wear a lot more than I thought!! I have an extra in case you are like me, because the teenagers in my house won't wear off brands!!
