Ultra Running Bottles, Cups & Soft Flasks for Ultramarathon Runners

UltrAspire bottles use a BPA -free LDPE for our running bottles, which is preferred over PP for most sport applications because of its hand feel and squeeze-ability. (We know what it’s like to be a fatigued runner in the later stages of a long race trying to squeeze an impossible bottle!) We also use Tritan, when squeeze-ability is not an issue and stability is preferred, and Silicone, both of which, have great taste quality.

Ultimate Direction bottles feature the incredibly innovative Kicker Valve, which is offset for easier drinking, easy grip leak proof sealing cap, and textured finger and thumb grooves.

Salomon soft flasks by Hydrapak are flexible so compress as you drink to eliminate water bouncing/sloshing inside and reduce sucking effort. Easy to squeeze - with bite valve. Carry this soft water/gel flask in your hand, shorts pocket or race vest pouch. Carry gels, water, electrolytes and other fluids such as milkshake.

Hydrapak soft cups are a portable and collapsible solution for cupless / cup-free running events. Can be used for water and hot drinks i.e tea coffee, hot chocolate, soup

Ultra Running Bottles and Soft Flasks for Ultramarathon Runners

What Makes our Handhelds / Bottles Better?

Human Bottles: Advanced Bottles that do more than just hold liquids. Patent pending shape and angled top designed to deliver fluids from either hand with the head and entire body more naturally positioned, requiring less effort and achieving greater flow. Polarity system™ also holds and stabilizes the bottle in the pack enhancing quick access and return.

1. Ergonomics: Our special shaped and angled running bottles may seem odd at first, until the mechanics of function is understood: First, the shape accommodates and feels good in your hand. Second, angles help deliver the fluids without the requirement of dramatically tilting back your head to allow for liquid delivery.

2. Polarity: Magnetic energy is lighter weight, and saves time and effort retrieving, stowing, and keeping hydration bottles in your pack; it may also impart substantial health benefits to the liquid enclosed. We did some research, we are convinced, that like water emerging from a mountain spring infused with the magnetic energy of the earth—it’s simply healthier for the human body.

3. LDPE: Our squeezable bottles are made of low-density polyethylene. This is a BPA-free material so you don’t have to worry about chemicals leaching into your fluid.
