Building a cheap Bug Out Bag.
I was looking to build a cheap Bug Out Bag for a colleague who asked what I would recommend on a budget, so it was to use some of those Autumn deals, which are currently available. The kit also was specified to be capable of sub zero temperatures in poor weather.
It was not going to use low end junk but some reasonably good specification kit with durability in mind. It turned out more expensive than I thought it would.
Here is how I got on for the Basic Kit that is probably not readily available already within a household. (i.e. doesn't include Outdoor Clothing such as Goretex Rain.snow gear etc)
Backpack/Rucksack  
PLCE British Patrol pack 38 Litres   these can be had for £25 (well made copies for £20), well this is what I was able to get on sale.  Big enough for  a72 hrs kit and is very durable and tough being constructed from camoflauge DPM IRR 1000 Cordura @1.6kg It also has numerous attachment points (Not PALS Molle) to add additional capacity to the pack.
Tent
