Great bra

Super comfy. First time with this bra ( i usually buy the energy). I think this one might be my new go-to! Love the soft material, support and it doesn’t pinch too tight. True to size

Mesh is so cool and refreshing

This bra is amazing, comfortable, yet it gives good support. The mesh makes hot workouts so much cooler! The mesh makes a huge difference!
