I'm experimenting with a Wazoo Cache belt to potentially replace part of my PSK. It has a lot of potential as an altoids tin alternative. Insufficient on it's own, but as a supplement to an EDC has potential.

I very much like the idea of being able to carry a couple of 1 liter water carriers and purification tablets (among other things) even when I don't have a cargo pocket, such as when wearing jeans.

I was able to fit a space blanket in there, so I will try again with a more durable SOL blanket. I do wish it was a 1.75" belt rather than a 1.5"... I may have to experiment with making something of my own.
