Designed for quick pit stops at aid stations, this HydraPak UltraFlask Speed 500 water bottle shrinks as you drink to minimize sloshing and feels so light you might even forget you brought it.
- Soft material conforms to any pocket, in a size that's ideal for hydration vests, belts or pack pockets
- Large 42 mm opening lets you fill the UltraFlask easily with ice and drink mixes
- Speedfill™ cap flips open for quick refills and snaps closed for a spillproof seal; high-flow bite valve auto-seals after each sip, eliminating drips
- Cap features an adjustable, removable drink tube and removable bite valve for easy sipping
- Bite valve can be mounted directly to cap, so you can use the flask with or without the drink tube; tube can be cut to any length
