Hi,
Its called a Tentipi, made in Lapland, Sweden. You can buy them in the UK now. This is the smallest one classified as a 5 man, 4 is very comfy with even with all 8 panniers inside.
They come in a few different classes/prices. This is the cotton/ nylon mix which is breathable, but heavier at 9kg/ There is a rip stop nylon one at around 6kg.
They are expedition tents - 4 season spec- and stick to the ground like limpets. Check out any Antarctic tents,they use this shape too.
What makes them SOOO special is that you can light a fire in them, an open fire in a tin box or on the ground! The ground sheet zips opens up to accommodate. I also have a wood burning stove for winter camping that all folds down into a small bag the size of a small lap top and at around a Kg or so, with the 7 foot chimney too in the bag.
So, if you want , at the end of a great days cycling, to sit in a midge free, dry place,even in the middle o a Scottish winter, toasting away, with your mates drinking fine malt whiskey, sitting around an open fire, talking shite -this is the tent!
