Rugged Xtremes Vacuum Insulated 550ml Thermal Mug – Stainless Steel with Sport & Sipper Caps

The Vacuum Insulated 550ml Thermal Mug is designed for durability, convenience, and all-day temperature retention. Constructed from high-quality stainless steel, it offers long-lasting performance while remaining easy to clean.

Featuring dual-wall stainless steel construction with vacuum insulation, this mug keeps beverages hot or cold for hours, making it ideal for work crews, outdoor use, and daily hydration.

The wide mouth design allows for easy filling, cleaning, and adding ice. It comes with two interchangeable screw caps—a sport cap for quick access and a mug-style sipper cap for controlled drinking—giving users flexibility depending on their needs.

Finished with a hard-wearing hammer powder coat, the mug is built to handle tough environments while maintaining a secure grip. The lid system is fully compatible across the RX11D bottle range, making it a versatile addition to any setup.
