Price: £45 + p&p
Osprey Atmos 50 backpack.
Used quite a bit but still got many miles in it yet. Back size large.
This is a great rucksack and I have been given the 2012 version. I would buy this again and again. Great for overnight trips and packed full of features. See here for full details:

It shows the signs of regular wear and tear (see pic slideshow for details: http://imageshack.us/photo/my-images/99/p1030889g.jpg/ )
One rip on the front right pocket along the seam. Easily repaired by someone with sewing skills.
RRP is £120. Cheers.
