The Stanley Transit Flip Top Mug 0.47 L in Shale Metallic is the darker grey in the AeroLight line. AeroLight is Stanley's answer to the complaint that vacuum mugs are heavy: the steel is spun thinner, the double wall stays, and the mug comes out noticeably lighter than the standard range.

• Shale Metallic: a deeper metallic grey that hides marks better than the pale colourways.
• Spun steel body: thinner gauge than Stanley's usual drinkware, without giving up the vacuum layer.
• One handed flip lid: opens for a sip and locks closed for the bag.
• 6 hours hot, 8 cold, 30 iced: real insulation despite the lighter build.
• Material: Made from recycled 18/8 stainless steel.
• Lid and base: Silicone lid tab and base pad, cup holder compatible, dishwasher safe.
