I am a 34DD which makes it difficult to find good running bras, especially if they have a racer back. Most running bras with racer backs are so difficult to put on that I get panicked because the bra gets stuck half-way on and I can't get in or out. Not with this one. While it's not as easy as a regular running bra, I can actually get this one on and off with very little difficulty. The size is perfect and the fabric is wonderfully soft. I love the way it supports during the run. Prior to finding this bra, I wore Moving Comfort's Maia bra. While that is still a great running bra, this bra is now my go-to. A bit pricier, too, but I think it's worth it. The only thing I notice is that it holds the moisture. When I take it off after a long run, it is sopping wet.
