Keep your water colder longer. An insulated version of our handheld flask, the 500ml SkyFlask IT incorporates our IsoBound™ technology. Designed to keep liquids at an ideal temperature 38% longer than a standard water bottle.

• Adjustable Hand Strap | BPA and PVC Free | Isobound Insulation | Speedfill Cap. 
• Thumb Loop: Innovative thumb loop allows you to hold the flask securely in either hand without gripping or squeezing. Soft, neoprene padding provides a comfortable and chafe-free fit.
• Adjustable Strap: Sweatproof strap can be adjusted to fit a wide variety of hand sizes, the Velcro style strip ensures strap stays in place while on the run.
• Hold With Either Hand: Versatile and ambidextrous, the flask can be carried in either the left or right hand, with or without the thumb loop.
• Isobound Insulation: Keeps your hydration colder longer. Double-wall construction and cell foam technology create a barrier - slowing the heat transfer from the user to the hydration.
• Compressible: Flexible design shrinks as you drink, reducing water movement and easily stores away in your pocket when empty.
• Speedfill Cap: Designed for fast filling - flips open for quick refills and snaps closed for leak-proof seal.
• Easy to Clean: Hand strap is removable for cleaning. Flask and cap can be placed in dishwasher and the strap hand washed.
