Although Tentipi's Nordic Tipis have been designed to function well without an inner-tent, they do offer a number of advantages. They protect against condensation that is caused by ground dampness by covering the entire floor, offer more reliable protection against insects and distribute and retain heat more evenly, especially when used with a stove.Three fresh air intakes align up with the Tipis vents for a fresh air flow, especially important with the use of a stove, and mosquito-net fitted doors provide good ventilation on warm sunny days. The roof insect mesh can be closed around the centre pole or tucked away to reduce the risk of damage when in use with a stove or open fire.The groundsheet features a zip running away from the door, so it can be pulled back to prevent water setting if the door is open in poor conditions and the centre of the groundsheet also has the same zip features, so the centre of the sheet can be pulled back to facilitate a stove or a fire box.The Innerlix C, Teflon treated Rip-stop polyamide fabric is ultra-light and is designed to breathe out condensation but also prevents condensation from the tent coming in, providing a comfortable living area.Easy to set up, they can be left attached to your Tipi for quick and easy pitching.This inner-tent can be used with any size 9 model.
