I bought this bra after I recently took up running, as I wanted something specifically intended for this kind of exercise. I already own a couple of Shock Absorber bras, but these are both intended for lower intensity exercise, and I tend to wear them on gym equipment such as cross trainers.
The first thing to say about this bra is that it is incredibly comfortable. When I first went to put it on it felt like it was going to be very tight, but in fact it just sits snugly on the skin with no discomfort whatsoever. Also, rather than having to pull it over my head like I have to with my other Shock Absorber bras, this one fastens like a normal bra, with an extra clip at the top (which was a little fiddly the first time I tried it on, but I quickly got the knack). It feels incredibly well made, and as for its ability to control any unwanted "bounce" whilst running, it is simply brilliant. It really does support the bust extremely well, without leaving you feeling like you're restricted. I also personally found that the bra runs true to size.
Really cannot recommend this highly enough, and I'll definitely be getting another.
