Green-LAM: Green-LAM is created with Fleurville's very environmentally friendly polyurethane laminate. Green-LAM has superior attributes like moisture-repellency, UV-resistance, and overall durability. Most other bag companies use PVC for this application. We don't. We hope you share our commitment to teaching children responsible stewardship of our environment. Our launch of our fabric treatments Green-LAM and now Re-Run will further minimize our products' impact on our share resources.
