I am getting on a bit..... well my body is about 40 years older than it should be lets say :P
So when camping i like to be able to Stand up and get dressed, be able to move around in the tent and have an air bed, chair, heater..... you get the idea :P
So 2 years ago i brought a Teepee.
very easy to put up on your own, its peg out the base, insert the 1 pole and peg out the guide ropes. its up in 2 mins flat to give you cover from the rain.
its 2 meters high in the centre so easy to get dressed and is big enough for me on a double blow up bed, a mate on a double blow up bed, all our gear and if i felt like it the bike to :P
yet it packs down small and light as its just 1 pole. my sleeping bag takes up more room than the teepee.
it hasnt leaked in the 2 years use (been used 3-4 times a year) but it is only single skined. so can get a little cold, but thats why i have a gas heater i pack on the bike to
they SAY it sleeps 12, but by the time you have gear etc in i would say 6 max so for 2-3 ppl its a bloody hotel
yet packs smaller than a sleeping bag.
