Stem was developed as a successor to Rivers' popular stainless steel bottle Flasker. This is a high-spec model that combines higher performance and usability. It is a bottle that can be used not only for everyday use but also in harsh environments such as snow and mountains.
A premium water bottle and flask that weighs in at only 200 grams while offering unprecedented and prolonged hot and cold temperatures - hot up to 12 hours and cold 24 hours
The lightweight stainless steel has an internal copper coating which prevents heat from escaping and means that the bottle is ideal in situations when weight is at a premium - it's the ideal travel partner whether commuting or climbing
The secure screw lid means it is leak proof and the secondary filter allows it to be used for fruit infusions and regulates the flow rate for comfortable drinking even when on the move
The considered cylinder size fits well in the hand and with a capacity of 500ml it can contain enough water for up to four hours
All components are dishwasher and the wide neck makes it easy to insert a bottle brush for easy cleaning
