The 3FUL Lanshan 2 4 season inner tent is a direct replacement for the standard 3 season inner that comes supplied as standard with the Lanshan 2 tent.
The 4 season inner features less 'mesh' material, which in turn provides better heat retention and therefore is a warmer environment to sleep in. The inner however, still does feature 'mesh' for ventilation purposes in order to help prevent condensation.
Weight is approximately 500gr.
210 x 110 x 125cm L, W, H.
Please note that the hiking poles are not included. But are required to pitch the tent.
I have included an image of the standard 3 season inner tent for comparison purposes.
