The Nathan Sports Fire & Ice Insulated Sports Flask is sold in a two pack to give you a total capacity of 470 ml of hydration fluid for when you are running, hiking, on your bike or in the swimming pool or the sea.

’Ice’ in the flask title refers to the fact that its construction boasts innovative double-walled insulation that will keep your drink cooler for 20% longer than other insulated bottles.

’Fire’ refers to the integrated high-vis reflective fabric that will never wear out and that provides a very high level of 360° reflectivity for visibility in low-light conditions and darkness when the flask is struck by the illumination from a vehicle’s lights, for example.

The Race Cap fitted to the Nathan Sports Fire & Ice Insulated Sports Flask allows you to take on fluid in quick bursts without disrupting your progress.
