Print care notes: A temporary glossy appearance from the printing process can wash out. Heat pressing can cause temporary shading around a print; washing may reduce it. Follow the garment care label.

Fabric, coverage & fit

The A4 N3142 performance crew neck uses 100% polyester. The supplier documents moisture wicking and UPF 44+ for the base garment. Short sleeves leave the arms exposed; the rating describes the fabric, not complete sun coverage.

Read the supplier specifications

Supplier specifications describe the base garment. Seven Casts physical samples and on-water field testing have not yet been completed.
