This is the most comfortable sports bra I have worn, yet it is also very functional.  I wear it for running and find it minimises bouncing very effectively while not being at all constricting.  The velcro adjustable straps threw me off a little at first, but I like them so much more than the slide adjusting straps.  Once you have got them at the length you want, they stay!  The reasons I gave it 4 stars instead of 5 are minor (and more to do with my way of rating things).  The material is quite thick.  I do not find it hot, but the bra is very noticeable underneath of what you are wearing.  I don't really care about this when I work out, but other people may.
