What is the HydraPak SkyFlask Speed 500ml?
The HydraPak SkyFlask Speed 500ml is built for runners who prefer carrying hydration in hand — without the discomfort or effort of constantly gripping a bottle. The innovative thumb loop and adjustable hand strap create a secure, natural hold, letting you stay relaxed and efficient mile after mile. Its minimalist, ambidextrous design allows for comfortable use in either hand, while the lightweight, flexible flask compresses as you drink to prevent sloshing and free up space. Topped with HydraPak's SpeedFill Cap, it opens wide for rapid refills and seals instantly for leakproof confidence on the move.
What is it made of?
The SkyFlask Speed 500ml is constructed from a blend of TPU, PP, Silicone, and POM, carefully chosen to balance durability, flexibility, and light weight.
Durable TPU Body
The thermoplastic polyurethane (TPU) body is soft yet abrasion- and puncture-resistant, allowing the flask to compress naturally as you drink while maintaining long-term durability. This flexibility ensures the bottle conforms comfortably to your hand and folds flat once empty for easy stashing.
Leakproof RF-Welded Seams
RF-welded seams reinforce the flask's structure, providing a watertight seal that stands up to repeated squeezing and pressure without splitting or leaking.
Comfort-Oriented Components
The neoprene-padded strap and thumb loop offer chafe-free comfort, even over long distances. Meanwhile, PP (polypropylene) and POM (polyoxymethylene) components add lightweight rigidity and structure to key areas, ensuring easy handling and stability.
Safe, Clean Hydration
All materials are BPA- and PVC-free, meaning your water stays pure-tasting and free from chemical odours. Designed for repeated, high-intensity use, the SkyFlask remains hygienic and comfortable from your first run to your hundredth.
What are its features?
The SkyFlask Speed's ambidextrous design allows you to carry it comfortably in either the left or right hand, with or without the thumb loop. This versatility allows you to switch sides mid-run to reduce fatigue and improve balance during long efforts.
Innovative Thumb Loop
The ergonomic thumb loop eliminates the need to grip the flask tightly. Instead, it naturally anchors the flask to your hand, reducing muscle tension and wasted effort. The soft neoprene lining prevents rubbing and ensures a smooth, irritation-free fit even when wet with sweat or rain.
Adjustable Strap
The minimalist hand strap provides a secure, custom fit for a range of hand sizes. Constructed from sweat-resistant fabric, it stays comfortable and stable throughout your run, while the Velcro-style closure locks it firmly in place without slipping.
SpeedFill Cap
The SpeedFill Cap flips open for fast, one-handed refills and closes securely with a simple snap to prevent leaks. Its wide opening makes topping up at aid stations or from bottles effortless — a key advantage during races or time-sensitive transitions.
Easy to Clean
Every component of the SkyFlask Speed is built for convenience. The removable hand strap can be hand-washed separately, while the flask and cap are dishwasher safe. This easy-clean system ensures hygiene between runs and extends the lifespan of your gear.
Compressible Design
As you drink, the flask shrinks naturally, preventing sloshing and maintaining balance in your hand. Once empty, it folds down compactly to fit in a pocket, running vest, or waist belt. The flexible design ensures minimal bulk and maximum performance on the go.
