About Hydrapak UltraFlask 500ml 2-Pack - Collapsible Soft

Part of our ultra-light series, the UltraFlask 500 mL is so light, you might forget you brought it. Weighing in at just over an ounce, it’s optimal hydration, no matter what kind of runner you are. Its pliable material conforms to most pockets, it shrinks as you drink to minimize water movement and it can be used with or without the tube. Ultra light weight, ultra useful. The ultra lightweight UltraFlask is adjustable to your hydration needs. Customize your cap with two options depending on your run or vest, directly mount your bite valve or use the straw cap (which can be cut to any length). Made of ultra-durable, abrasion resistant TPU & RF welded seams for superior durability and elasticity, the UltraFlask 500 can stand up to whatever you throw at it.
