This top is a lightweight material, 55% Organic Cotton, 40% Viscose from Bamboo and 5% Elastane.  The top is moisture wicking, UPF 50+ protection, Anti-odor, Breathable and Lightweight.  The elastane give the fabric some stretch.  

This top is a very nice lemon yellow, the first couple pictures are likely the closest to the actual color.  It is a little bright but by no means a neon yellow.
