Up for sale is a lightly used Laufsbursche huckePACK: http://www.laufbursche-gear.de/products/huckepack/
I purchased it from Nic in July, and after some use have decided that it's not for me: http://www.bushwalk.com/forum/viewtopic.php?f=57&t=17600&p=235340&hilit=huckepack#p235340
The specs:
Size: Large, for torso lengths: 49 - 57cm
Capacity: Around 45L
Material: Black cuben
This pack doesn't work for me because I use the one bag for everything - going to uni, transporting groceries from the store, and backpacking as well. With the pack sometimes mostly filled full of solid things and very variable loads, it's very hard to be comfortable, even when coiling up a sleeping mat as a frame and packing carefully. As such I've gone back to my original GG Gorilla, which is inferior in most ways, except that the aluminium frame it comes with makes all the difference in handling those loads I've described above.
On the positive side, the shoulder straps are comfortable, the quality of manufacture is spot on, and having been caught in a downpour or two with the huckePACK on my back, I can vouch for its water resistance.
Things to know
Most reviews of the original huckePACK mention that it comes with shock-cord which can be laced up on the back panel, and then used to hold a foam pad or sit mat for back padding. When I purchased the bag from Nic, it didn't come with this, as such, I don't have it. However the loops for you to lace your own shock-chord through are there.
Condition
Very good overall. There's a small tear in the left side mesh pocket where the mesh joins the elastic. You can see this in picture 4.
