With a built-in refreezable gel pack, the Perma-Frost Hydra Bottle is ideal for accompanying you on long, summer rides.

It can hold up to twenty ounces of liquid and can withstand both sub-freezing and boiling temperatures.

There’s no need to add ice to your drink with this bottle, simply pop the Perma-Frost Hydra into the freezer for an hour and then you’re good to go.

Unfortunately the bottle is currently out of stock on most UK sites but you can have it shipped over from the USA by ordering one from Brookstone for around £11.
