I've been waring this binder for a few weeks now and am very pleased. The it's very breathable which is a game changer for me, and the free custom sizing option is very worth the wait in my opinion. It fits so well, It doesn't rub in weird places or pinch. It just fits. All the seams are finished inside the garment and it looks very clean and professional.
The mesh does however, have an inorganic, manufactured textile smell that doesn't wash away, so if you're sensitive to smells keep that in mind.
