The Ultraspire 2.0 Bladder is a 1-liter, BPA- and PVC-free hydration reservoir with a wide slide-seal opening and a leakproof plug-and-play tube for easy refilling and reliable flow.

Engineered for runners, cyclists, hikers and everyday commuters who prefer a lightweight, high-quality hydration solution, this 1 L Ultraspire reservoir combines durable HydraPak film, a user-friendly slide seal, and a quick-attach tube to keep water tasting fresh and delivery consistent. The design focuses on maintenance simplicity and fast drinking performance without introducing plastic taste or harmful chemicals.

How quickly can I refill and clean the Ultraspire 2.0 Bladder?

Refilling is fast thanks to the wide slide-seal top that opens fully for large pours or ice cubes. For cleaning, the bladder can be turned inside out to reach all corners, and the slide seal seals tightly afterward so you won’t worry about leaks during reassembly.

• wide slide-seal opening for rapid filling and ice access
• bladder inverts for thorough hand or brush cleaning
• secure closure prevents spills while transporting or refilling

What materials make the reservoir safe to use and taste-neutral?

The Ultraspire 2.0 uses premium HydraPak film that is free from BPA, PVC and phthalates, so stored liquids remain free of chemical aftertaste. The material selection keeps the reservoir lightweight yet resistant to stretching or puncture under normal use.

• 100% BPA- and PVC-free construction for cleaner taste
• phthalate-free film reduces off-flavors and odor absorption
• durable HydraPak material balances flexibility with puncture resistance

How does the tube and valve system perform during activity?

The reservoir ships with 5/16" diameter tubing that supports higher flow for quick sips without excessive suction. Tube attachment is plug-and-play for fast setup, while the bite valve and tubing positioning minimize accidental leaks when you’re on the move.

• 5/16" tubing diameter for a responsive, higher-flow drink
• plug-and-play connection for fast assembly and replacement
• standard UltraRed tubing color for visibility and easy routing

Will this bladder fit my pack and how many sizes are available?

The Ultraspire 2.0 reservoir is designed to nest in most hydration-compatible backpacks and vests. While this listing is for the 1 L version, the design is also produced in a 2 L capacity for longer outings or group needs.

• 1 L size for lightweight, short-duration use
• 2 L option available for extended activities or shared systems
• slim profile fits common hydration sleeves and vest pockets

Who is this for: The Ultraspire 2.0 Bladder is ideal for trail runners, mountain bikers, day hikers and commuters who want a small, easily maintained hydration system that won’t add bulk or impart tastes.
