I spent two months this year in Iceland, then we headed to Germany, with very few exceptions, I carried this tripod.

There are some outstanding features of this tripod as far as I'm concerned, firstly it folds down to 35cm and very easily fits into my 35 llitre day back pack. It also fits into many other things as well; in fact, we have carried it in little aluminium cases and once in a small unused fishing tackle box along with other stuff to keep things dry.
The second amazing feature, is weight, it is very light, hovering around the 1kg mark including the small but excellent head.
The third very good feature is the monopod, which is made by partial disassembly and re-assembly using the gold leg of the tripod and the extending centre column; this works very well with a Nikon F3 with MD4 drive and 180mm lens, which is an unwieldy combination as it is front heavy but works well with the monopod.
I am not saying this is a super sturdy tripod, but I can tell you, the tripod you can carry and have with you, either because of size or weight, is the tripod you will use.
I have had this tripod for 3 years now, it is the tripod I now take whenever I am not using a 4x5 camera with my Berlebach tripod. There are certainly better tripods, really better tripods, but this one for travel, is the bee knees.
If you search for Q-666C this is the one, cheaper alternatives do not have the capital letter C at the end. "C", denotes carbon fibre.
