Any on now of a good light weight 2 man tent thats been tried and tested by bushcraftuk members! This is my problem i had bought a helsport porsanger lavvu 4-6 man tent with a oven as well in feb this year,I have only used it once in the snow which was great and my son loved it!.But the problems is we are now spending more time in the mountains with bivvi bags at the mo,But when we hit the forest we sleep in the hammocks,So i was thinking of selling the helsport porsanger lavvu to get a good 2 man tent for winter and the mountains but must be less than 2kg as i have to carry my son's kit as well (7 year old).Any thought's on it guy's?
