At first the top seemed too artificial material. I contacted customer services, and one of the representatives convinced me of the material properties & suitability for fitness. It is now my favourite gym wear, it's very light & comfortable, extracts body sweat & does not stick to my body during long cardio sessions. The overall design is great; subtle, simple & of course elegantly black. I never paid much attention to what I throw on myself when going to the gym, but now I actually feel & look good. I'll watch this space for more products in the future.
