I have to ask, but what is the anticipated use of this BOB?


The specification of the BOB is to allow someone to be mobile (reasonably lightweight, no more than 40lbs) and have the ability to survive over a range of terrain, weather and temperatures (lowest overnight freezing temperatures down to -5 to -10C) for a period of time of around 3 to 7 days. It can also provide useful equipment and dry cold weather clothing even for bugging in, where there is a lack of stored food, no electrical and LPG gas supply and water needs to be made potable for a similar timescale.

Realistically, this looks like a decent start at a low-cost backpacking & camping kit


Yes, it is the basis for a BOB. Many BOB videos on Youtube will fail miserably in real world testing e.g.

A good tent, sleeping pad and a good sleeping bag really isn't a luxury in more challenging conditions.

Cold weather clothing is also very important as clothing found in the wardrobe might not be suitable.

MoD Issue Reversible Green / Sand Thermal Bivvy Jacket - £30
