Ultra Running Bottles, Cups & Soft Flasks

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
