Tactel Aquator / Tactel Mirco fabric makes for a very soft, very comfortable and supportive compression bra that also looks good as a crop top. The Sweet Pink is a lovely, strong shade that keeps its colour and doesn't fade in the wash; same with the black. Good impact level for the A/B cup, I wear mine for sport and run; the C/D cup gives good support but probably more for the gym, workout, yoga session than a run. Having said that, as these are a compression bra if you want to up the impact level you can just order a cup size smaller.
Mesh on the racer back panel gives great ventilation and looks good to, works well with the rest of the Casall range of tops.
