I'm a 36DD, and I'm training for a marathon. I've gone through so many Champion and Moving Comfort bras looking for the perfect non-chaffing, supportive fit. I finally broke down and decided to splurge on this one after two recent failed attempts on my long runs with two different Champion bras that felt fine for the first few miles but didn't feel so great for the last miles. This bra provides great support with the comfort of no poking underwires and incredibly silky material. It is defintely worth the extra money. I also love that I don't have to wriggle it over my head then reach around the back to get it fastened.
