Moisture barriers inside shadowboxes — what it reveals about sports jersey preservation Moisture is one of the most overlooked threats to sports jerseys. And most people don’t even realize it’s happening. Jerseys absorb humidity from the air. Inside a sealed shadowbox, that moisture can become trapped—creating long-term damage conditions. Over time, this leads to: • Fabric weakening and breakdown • Odor retention inside the display • Subtle discoloration • Loss of structural integrity The worst part? It builds slowly—and invisibly. At Picture Worth Custom Framing, moisture control is part of the shadowbox design. We account for: • Internal airflow balance • Materials that resist moisture buildup • Proper spacing to prevent trapped humidity • Structural design that supports long-term preservation Because a jersey doesn’t just need to look good today. It needs to last.
