HydraPak UltraFlask Speed 600ml 2-Pack for Hydration Vests and Running Packs

The UltraFlask 600 ml, the largest of our ultra-light series, holds more so you can go the distance. Its soft material allows it to fit snugly in most vest pockets, and it shrinks as you drink to minimize water movement. Topped with our SpeedFill cap for quick aid station refills, the UltraFlask 600 ml is ready for use with or without the tube.

Included in the package are the UltraFlask 600 ml Flask, SpeedFill Cap, Drink Tube, Bite Valve, and Basic Care & Use Instructions. The UltraFlask has a capacity of 600 mL / 20 fl oz, weighs 46 g / 1.6 oz, and measures 186 mm x 81 mm / 7.3 in x 3.2 in. It is made of TPU, PP, Silicone, and POM.

The UltraFlask is HYDRATION VEST COMPATIBLE, fitting easily in most hydration vests, belts, or pack pockets. It provides bounce-free stability and a flexible flask shoulder to prevent chafing.

The COLLAPSIBLE FLASK design features a soft material that conforms to any pocket and shrinks as you drink to reduce movement and pack away easily when empty.

The UltraFlask is PERFECT FOR AID STATIONS, equipped with our SpeedFill Cap designed for quick and easy refilling. A side tab pops open the cap in one motion and snaps shut with a click.

The UltraFlask comes with a CUSTOMIZABLE CAP, built for versatility. You can choose between a straw or bite valve.
