When we aren't thinking about the latest and greatest in sports nutrition, we are thinking about gear... and HydraPak has our back with their fantastic products. 

These Ultraflasks scream functional design and all the utility you could ask for whilst on the run. This essential equipment is made for every runner or adventurer and the Ultraflask series flattens for maximum room in your hydration gear bag. Expands for use on the trail or when on the go. It’s also super compact, flexible and 50% lighter than a tradition hydration bottle. HydraPak calls it construction with purpose. We couldn't agree more! Did we mention that they come with a "Beyond Lifetime Guarantee"!

Here are some of the great features:

• Thee UltraFlask fits easily in most hydration vest, belt or pack pockets
• Soft material conforms to any pocket for a comfortable carrying experience
• Flexible design shrinks as you drink, reducing water movement on the run. High-flow bite valve auto-seals after each sip, eliminating annoying drips
• Includes two cap sets: one with a removable bite valve mounted directly to the cap and one with an adjustable drink tube that can be cut to a custom length
• Large 42mm opening lets you fill the UltraFlask easily with ice and drink mixes
• Made of ultra-durable, abrasion resistant TPU & RF welded seams for superior durability and elasticity
• Can be frozen or filled with hot water (max temp 60° C / 140° F)Top-rack dishwasher safe
