In reply to HighlandStu:
Have 3 of them here purchased around 2009 and they have colour coded poles. Wouldn't recommend them unless cheap for the following reasons:
1. Thin groundsheet lets water through on snow and gets damaged on any other surface
2. Tent outer walls are not low enough and let spin drift blow between inner and outer
3. Zips and tabs not very durable
4. Quite hard to avoid outer and inner sticking together in extreme conditions which causes leaks due to guys loosing tension.
5. Big footprint can be a problem in the alps as it doesn't fit in many pre-made bivvi spots (double porch design)
They are the lightest tent I am aware of their type but sacrifice too much durability and the design has not been improved in a very long time even though there are obvious minor issues.
