Bottled oxygen is oxygen in bottles, such as for high-altitude climbing. Bottled oxygen may be for a breathing gas.

When Tenzing and Hillary made the first successful summit of Mount Everest in 1953 they used bottled oxygen.[1] It was noted for its ability to increase the user's appreciation of the surroundings.[1]
