A while ago I was looking around for a replacement of my Ortleib A6 drybag/document wallet that I kept my blood monitoring machine in. The one I owned had turned that nicotine yellow colour and the Velcro strip was starting to come away. In mid Wales a month or so ago it all came apart, rendering the thing unusable. At the time I was lucky to find a shop that sold them so bought a new one.
The size of the bag is ideal for my machine and I can fit a few spares in there too. But the trouble comes when I try and fit my insulin pens in as well. Careful packing is required in order to ensure that the top rolls down and holds securely.
At the BPC AGM at the weekend I came across the Exped Vista, which reminded me of a water resistant pencil case. That got me thinking so I headed back to the tent and grabbed my kit. Back at the stall the pencil case swallowed the two pens, and the blood monitoring machine with ease. Now unlike the Orteib bag it isn't waterproof, it has one of those proofed zips instead of a roll top, but the seams are sealed. My thinking is that as this will be carried in a rucksack pocket it will be fine in most cases. It weighs the same as the Ortlieb bag too (20g), and comes with a clip on one end. This is useful, clipping the case to the keyring in the rucksack pocket means it shouldn't fall out and get lost, and I can hang it up in the tent where the stuff has no chance of getting stood, sat or knelt on. An added bonus is that the zipper pull has a glow in the dark tab.
What's more the case has enough space for spare needles, lancets, and my other daily medications which means the other case I use can be left out saving me 64g. Joy.
