So, my bag is a Viper Recon Bag which has more than enough room for this stuff plus whatever else I have at the time - laptop, training materials, shopping etc etc. It is a great bag, they sell for 35 quid but are a proper working bit of kit with chunky zips and both chest and waist belts. It has space and holes for a water system and the various pockets are great for keeping everything tidy. I have given these away to loads of family and friends as well as sold a good few, they go down a storm!
In addition to the contents of the bag I also always carry a 3" locking knife with a part-serated blade. As well as a LED Lenser P7 torch.
In the bag I have:-
Empty aluminium water bottle (my home, work and car all have lots of bottled water that gets used and replaced all the time),
Microfleece towel (useful for all sorts of things including first aid and so light it is silly not to carry one),
Length of paracord tied in a braid and looped,
Mole-grip multitool and separate folding hand saw (neither are super-quality but good enough for a quick trek),
Clip on LED torch (not so bright as to attract attention or ruin night vision),
Headset for the radio, headset for my phone and sunglasses, notepad and pencil,
Boafeng two-way radio, pre-set with maritime, search and rescue, HAM, business radio and PMR frequencies,
Some sweets of some sort (lost count of the amount of times a quick sugar kick has helped),
Good old waterproof matches!
My car has a separate first aid kit and at home I have a very comprehensive one, either would warm the cockles of an A&E doctor.
I also generally wear clothes appropriate to the weather.
Things soon to be added....
Glass breaker and seatbelt cutter, alcohol gel, cotton wool, pencil sharpener, new charger for my phone (old one was not up to it), set of small reflective stickers for marking locations, Survivapure water straw.
On the nice to have list is...
Emberlit stove, a couple of tiny flash bangs, AAA battery pack for the radio.
Any suggestions would be most welcome, though remember this pack is designed to be light even when my day to day stuff is added to it.
I also have four separate locations with "stuff" squirrelled away.
