Hydrapak SkyFlask IT 500ml

Jump to: Our Verdict / Features / Specifications

Light and nimble soft flasks that mould and adapt not just to your body, but also to accommodate how much water is in the flask .

Hydrapak says

Keep your water cool and prevent bottle sweat. An insulated version of our handheld SkyFlask™ 500ml soft bottle, the SkyFlask IT 500ml features our IsoBound™ technology. Engineered to keep fluids at an ideal temperature 38% longer than a standard reservoir.

Our Verdict

Made of lightweight TPU, this flask will fit any stander running vest or pack and will keep your drink cool for longer. I like the way the bottle can compress to minimise the amount of room the flask  takes up in your pack or vest, but it also stops water sloshing about as you move.  The 42mm mouth makes them the perfect size to accommodate the Katadyn BeFree Water Filtration System.
