Like many I wanted a nice rugged backpack to carry all my precious kit. I was recomended a Karrimor Sabre. The Sabre looked fantastic but was just too far out of my price range. Instead I bought this:
Instead of the £50 being sold for here I found it for £26 on ebay. I couldn't be happier with it.
The toughness is superb I've taken it out on several night exercises for CCF and it's held comfortable:
Role matt (outside of bag)
Axe (outside of bag)
Fire starting equipment (tinder, firesteels and hexy blocks)
3 days worth of spare clothes
and a few other essentials. (head torches water bottles etc..)
Also it has a great orange rain cover that is packed up and stored in a tiny compartment in the bottom, it's always attached to the bag so it can't blow away (useful on the mores!)
The frame I found brilliant because it is a very central position on the back, anyone who's tried to go through the woods with one of those massive hiking backpacks on will know how anoying it is to fall ass over tit when you get caught on a branch. I also found it light on my back which had an injury a few years ago and used to wreck when I put on a heavy burgen.
Hope this helped
