Initally I found it difficult to put on, once I got the procedure down it was easy... I'm not able to keep the closed zipper from popping out away from my sternum which creates a lump in my shirts. I would like it better if I could cause the zipper to stay close to and touching my chest so I don't get the mono-boob affect. I'm very big chested, I carry a lot of my weight in my boobs. Perhaps that's the problem. Perhaps I didn't get the right size. It's a comfortable bra, Haven't been able to use it during horseback riding though. I'll have a three day event in December where I'll be able to check out the 'bounce arrest" It's a quality item, built well. It's reasonably priced and much more comfortable than other sports bras I've tried. Thank you for the opportunity to tell you this.
