The Nathan Sports SpeedDraw Plus Insulated Sports Flask is the first-ever 18-ounce double-walled insulated hydration flask.

This is a sophisticated flask for runners that also provides a very convenient way for you to carry additional essential personal belongings such as phone, keys and so on in an expandable zippered pouch.

Nathan Sports Fire & Ice technology means this flask increases your visibility through its high-vis reflective surface and also keeps your hydration fluid cooler for longer.

It will keep your fluids cooler than its competitors can manage and its Race Cap enables you to benefit very conveniently from quick bursts of fluid through its high flow rate and a one-way valve that opens and closes automatically.

The Nathan Sports SpeedDraw Plus Insulated Sports Flask boasts a fully adjustable hand strap that, with the thumbhole it also features, gives you a comfortable, secure handhold without you having to grip.
