Extra strong and safe four-season tunnel tent optimized for exposed conditions and challenging terrain. Full height in the entire inner tent and the large vestibule makes tent life comfortable, especially when bad weather keeps you inside. Adjustments and zipper pullers are big enough to be easily handled with winter gloves on, the guylines have a reflective thread woven in and are extra strong with double adjustments. The tent pegs are also extra long and wide for superior grip in difficult terrain. Reflectors at the vents and doors make it easy to find your way back to the tent in the dark. The flysheet and inner tent are connected so the inner tent is protected from getting wet when pitching in the rain. Pole sleeves are color coded for easy handling and are big enough for double poles so the tent can withstand even higher winds and more snow on the roof. Inside, the tent is spacious with a generous sitting height. Two entrances make it easy to get in and out and also give the possibility of using the lee-side door in bad weather. Large, highly positioned vents give excellent airflow and minimize condensation. All openings have fine mosquito netting and can be covered with the flysheet on the outside if the tent is used in snow or sand. In warm weather, the doors can be fastened in a half-opened position the zippers have an auto-lock function so they won't ''creep'' in strong winds for extra ventilation without rain getting into the inner tent. The flysheet is made from Fjallraven's new high-performance TripleRip nylon fabric. Its innovative construction combines two fabric weights for optimized strength 40 denier at the top with 70 denier reinforcements at the bottom where abrasion from the ground is the highest. Keb Endurance 3 is made entirely without PVC plastic and toxic flame retardants, and the impregnation is fluorocarbon free. Weight: Total 4130g, minimum 3420g.
