The "moss green" color is a cosmetic option for the AquaFlask mug
. The benefits of the mug itself stem from its design features, not the specific color, and include: 
 
Temperature Retention: Double-wall vacuum insulation (ThermoGuard technology) keeps drinks hot for up to 12 hours or cold for up to 24 hours.
Durable Materials: Made from high-grade, rust-resistant 18/8 food-grade stainless steel with a durable powder coating finish.
Health and Safety: The mug is BPA-free and lead-free, ensuring pure-tasting, chemical-free drinks.
Convenient and Reusable: Designed to be a sustainable alternative to single-use plastic cups, it's reusable and generally dishwasher safe for easy cleaning.
Portable Design: Features a secure, spill-resistant or leak-proof lid and a shape that fits most car cup holders, making it ideal for commuting, travel, or hiking.
Customization and Protection: It can be paired with accessories like silicone boots for an anti-slip base and protection from dents, or different lids to suit various activities (e.g., straw lid for gym use, spout lid for hot liquids).
Sweat-Free: The exterior will not collect condensation, ensuring a dry and easy grip.
