Nathan SpeedDraw 2 18oz Ins. Flask

More Miles. More Water. No Compromise.

When the distance goes up, so does your hydration demand. The Nathan SpeedDraw 2 Insulated Handheld 18oz Flask is built for long training runs, half marathons, and any effort where 12oz just isn't enough. The updated ergo flask shape is easier to hold and squeeze, and double-wall insulation keeps your water cooler 20% longer than standard insulated bottles — so you're still drinking cold water deep into your run.

The Push-Pull Blast Valve™ cap delivers quick, controlled bursts of fluid without stopping, and the sweat-channeled no-slip grip insert keeps the flask secure even when your hands are wet. The fully adjustable hand strap with chafe-free thumb hole lets you run grip-free when you want to give your hand a break.

Organized for the Long Run

The large expandable mesh pocket fits most smartphones plus a zipper pocket for valuables — so your phone, keys, and nutrition are all accounted for. Integrated reflective print on the flask and strap adds 360-degree visibility for early morning and evening runs.
