The Explorer Flask Duo 1L delivers all-day temperature control with vacuum insulation that keeps drinks piping hot or ice cold for 24 hours. Perfect for hikes, beach days or mountain trails, it pairs durable construction with smart features built for the outdoors. The reinforced steel body ensures lasting reliability, while the 100% leak-proof design lets you pack it worry-free.
Each flask comes with two double-walled stainless steel cups that screw neatly into the top and bottom, offering 200ml capacity per cup and a plastic-free drinking experience. The wide base keeps each cup steady on uneven ground, while a silicone gasket prevents drips when stored.
A thick nylon strap makes it easy to carry or pour on the move, and the steel cap lid includes a smooth-pour mechanism that minimises spills and retains heat. Both the flask and cups are dishwasher-safe, making clean-up quick and easy after any adventure.

To clean the bottle:
Wash thoroughly with hot soapy water before using, but do not fully submerge in water. Wash regularly to keep clean and avoid odours. Store with the lid off and make sure you allow it to dry thoroughly after washing.
Remove the strap and lid before dishwashing.
To remove stains or smells:
Add one teaspoon of bicarbonate of soda and mix with hot water. Leave overnight with the lid off and then clean thoroughly. You can also try replacing bicarbonate with vinegar, but wash thoroughly afterwards with soapy water to remove any taste or smell.
Note: This design is not microwave-safe and should never be used in a microwave.
