Summit day on Elbrus calls for a reliable vacuum flask of about one litre. The current list for the nine-day programme from the south<\/a> specifically recommends a model with no button in the lid. The exact volume of fluid overall, and the plan of stops, are set by the programme, the weather and the guide’s decision, so no universal figure in litres can be laid down for every participant.<\/p>\n

Why an ordinary bottle does not solve the problem<\/h2>\n

In the cold of the night, water in a thin bottle cools quickly and can begin to freeze. Cold liquid is unpleasant to drink, and a frozen lid will not open at the moment you need it. A vacuum flask keeps the drink at a usable temperature and protects it from the cold outside.<\/p>\n

That does not mean the liquid should be scalding. A drink that is too hot cannot be finished quickly at a short stop. Settle the temperature beforehand and test it in training.<\/p>\n

Why a lid without a button is more reliable<\/h2>\n

A push-button mechanism contains small parts and channels where liquid stays behind. In the frost it can pick up dirt, freeze or start to leak. A plain screw stopper is usually easier to check and easier to clean.<\/p>\n

Any flask should be left full for several hours before the trip so that you can check how well it holds its temperature and whether it is watertight. If the lid is damp on the outside, or the body warms noticeably, the flask needs replacing.<\/p>\n

What to put in it<\/h2>\n

A familiar warm drink, and no experiments with new additives. A mixture that is too sweet or too strong can cause thirst or discomfort. If you use a sports drink, test it on a long training session before the trip.<\/p>\n

Alcohol is not a way of getting warm and should not be used on the route. Do not experiment with medicinal or stimulant additives unless there are medical grounds.<\/p>\n

How to drink at altitude<\/h2>\n

The UIAA advises keeping fluid intake sufficient but not excessive. Forcing large volumes down is equally wrong. Go by the guide’s plan, by what you can tolerate, by the effort and by how you feel overall.<\/p>\n

Small, regular sips are usually easier than occasional attempts to drink a lot at once. Do not wait for a marked dry mouth, but do not turn a figure chosen in advance into an obligation that ignores how you feel.<\/p>\n

Where to carry the flask<\/h2>\n

The flask stands upright and is secured so that it neither bangs against your back nor falls out when the rucksack is opened. The lid has to be reachable without laying your down jacket and first-aid kit out on the snow. A separate bag protects everything else if it leaks.<\/p>\n

The metal cup in the lid does not suit everyone: it can be dropped, and pouring takes time. Practise using the model you have chosen while wearing gloves, and decide whether you can drink safely straight from the neck.<\/p>\n

What to check the evening before<\/h2>\n
