This is probably the wrong time of year to mention buying more new kit but on the off chance we get decent summer and hence the need to carry extra water these plastic drink pouches may well be worth a punt. With a traditional hydration bladder sucking £12-15 out of your wallet a ten pack of these 32oz/1L jobs can be found online for under a tenner. They also come in four sizes 64-32-16-8oz (2L-1L-500ml-250ml approx) so handy for other liquids such as 40% proof muscle relaxant or just popping into your bug-out/ditch bag just in case the condom in a sock trick doesn't appeal.
