Pros:
Front adjustable straps,
Isolated/encapsulating cups give you less uni-boob and don't crush your bust sideways for support
Firm hold for running
Back hook closure makes removal easy (you don't need to dislocate your shoulders after a workout!)
Runs true to size compared to most every-day bras
Bottom edge elastic is wide and firm, so it won't roll up, and doesn't rely on being extra tight to fit properly.
Comes in B, C, D, DD
Doesn't pinch under the arms or under shoulder blades (fewer bulges).

Cons:
Plastic strap connector has scratchy edges if they touch your skin.
Velcro straps need to be adjusted so the end doesn't land on your clavicles (chafes on long runs)
The seam at the side of the bust is thick, and the fabric there isn't very supportive, so you can get the look of side boobs even when you're fit.
