Excluding the side rocket pouch - 100 litres.
Including the side rocket pouch - 110 litres.
This is large as a BOB should be really. A nice smaller one of about 60 - 70 litres is nice too. An entry size for those unknowing to the ways of
heavier BOBs.
If you are used to heavy bergens and weight on your back an 'entry' BOB could be any size!
I prefer the outer limits in size for greater range and distance while on the move.
With the BOB I've got I reckon on about 2 weeks purely on the food and gathered water from streams and lakes.
With the stuff you find, hunt and eat is obviously good for extending the BOBs supplies.
The biggest weight is the food and water. Camping gas should be kept to a minimum and used only if you can't find material nearby for fire
making.
You'll have pretty much most if not all the stuff you need to worry less on surviving locally, and more on getting to where to you are going and
setting up a base of ops.
One thing few people realise is that a persons build is as important in choosing a BOB as the BOB itself.
You can have a big bergen or BOB and that's ok, as long as your body-type is suited to it.
As a general rule of thumb stocky guys will do better with a more wider and stumpy type of BOB. Bigger / taller guys a taller, thinner one is a prime
choice for long-distance comfort.

When I was in the forces the 'issue' bergens for non-infantry guys were these crappy, dumpy things.
They are ok for stocky beefcake guys of a short height (up to 5"8).
So for some they are ok and do the job well but for most guys, the general feedback was and is that they are a sub-standard bergen and uncomfortable
at long-distance work when there's plenty of better ones.
The capacity is only 80 litres but for the design it ought to be more.
They zip up like a handbag on the top and getting all yer stuff in was a nightmare (zips are often the first thing to go).
With both rocket pouches on the side you may resemble a ninja turtle sans weaponry!
It must be said though that for all the criticism this type of bergen is very cheap and affordable (probably why the BA issues them to every tom dick
and harry!).
Some dude called Slipstream on flickr actually uses one of these for his BOB so for some people they are ok.
The next style of Bergen you see on my OP pictures:
Infantry PLCE bergen 100 litres, long back.
A variant on this is a shorter version of the Inf PLCE bergen known as the short back. I haven't seen too many of these around though.
Don't let the complex name put you off, I would easily claim this is probably one of the best big bergens in the world. The SAS / SF guys use this
and they aren't in the business of wearing crap so if big bergens / BOBs are your thing go for this option.
This is a very cool kinda bergen, even in the armed forces having one of these was and is usually uncommon outside of SF and Inf Regiments.
These days they are usually about $120 + but they have come down in price from the late 90s when $200 was not uncommon so now is a good time to
buy.
The only down side is that you will stand out the most in urban areas and military troops in the know may or may not suspect you're a prepped
survivalist (SITX). These bergens are available in Olive drab which is generally less noticeable than dpm but is scarcer to find these days.
The nice middle of the road option is the patrol pack:
This is about 50 - 60 litres all in and is a nice middle ground option.
A smaller option is the rocket packs joined together (zipped) and then using as yoke to shoulder them use them as a daysack. AKA rocket packs (if
only!).
This has never been my thing, you have a small compact BOB, BUT you've not got a true 20+ litre carrying capacity. More like 10 + 10 litres. It
also hasn't got the complete nature of the above BOBs which have the full harness adjustment straps and belts etc.
Civilian ones are ok. They tend to less robust though, which, while lending them a slight weight loss, means they are usually not as tough and the
plastic tends to weaken / break after a few months of use.
That said they are usually more discrete and ordinary looking / easy on the eye.
I use a north face civilian back-pack for traveling in abroad and despite only costing me $5 in a cambodian market in Phnom Phen it has lasted me 7
years (so far) of being lugged about on Dive Boats, beaches, countryside and backpacking all over the place.
That's about 30 litres which is good for civilised livin' without carryin' food, water, shelter and sleeping kit
