Ultraflask IT 500ml Water Bottle

The HydraPak Ultraflask IT 500ml Water Bottle is the perfect companion for your endurance activities. It is insulated with HydraPak's IsoBound to prevent condensational warming to keep your beverage at its ideal temperature as you crank through the miles. Its double-wall construction and cell foam technology creates a barrier to slow the heat transfer from your hands or body to the bottle itself so you can have a chilled beverage past the early miles. It fits easily into most hydration vests, belts, or pack pockets for your convenience and has a wide enough mouth to easily fill, add ice, or add drink mixes. Use either the cap with the bite valve mounted directly to the cap, or the cap with the adjustable drink tube that can be cut to a custom length so you can stay hydrated the way you want as you train.
