There is not much to talk about really. This trifling chunk of gear is just a handheld. Not your usual handheld though.
With a capacity of only 0.3 litres it is certainly not an immense chunk of water/plastic you have to transport. For me it is all I need during this time of the year. Ergonomically formed bottles are nice and do not always work for me. This one does.
The small mesh pocket conveys all I need during lunchtime or evening jogs plus a GoPro if you like. The “Handy 10” does perfectly work during my habitual day-to-day runs in the heat but not during longer races I guess.
And that is all I have to say. Simple does it!
