I am so happy I found this bra.  I have wanted a racer back forever but my size (34d) was hard to find with underwire and back clasps as an option. I have tried others and returned them all as they were impossible to get on and off and gave the uniboob look which i can't stand the look or feel of.  I actually slide this on over my legs,  do the clasps and turn it around then put my arms through.  Works like a charm. I now have 5 in total so I have enough in rotation....crossfit in the summer is just a sweaty mess and I am not doing laundry every day!  If you have been looking for a racer back with similar wants to mine give this a shot!
