Extra strong and safe four-season tunnel tent optimised for exposed conditions and challenging terrain. Full height in the entire inner tent and the large main vestibule makes tent life comfortable, especially when bad weather keeps you inside. Perfect for advanced winter trekking and tenting above the treeline, but still light enough to fit into a trekking backpack. All materials and details are carefully selected for their reliability and manageability in cold conditions. For example, 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 and the ground loops are big enough to be used with skis or poles when using the tent in the snow. 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 colour coded for easy handling and are big enough for double poles (an accessory) so the tent can withstand even higher winds and more snow on the roof. The extra large vestibule has plenty of room for storing gear, cooking and other activities. Two entrances make it easy to get in and out and also give the possibility of using the lee-side door in bad weather. An extra vestibule at the foot end of the tent provides an extra entrance plus additional space for gear. Inside, the tent is spacious with a generous sitting height. Clotheslines in the main vestibule and inner tent as well as several mesh pockets help keep gear organised. There are also attachment points for a Gear Loft (an accessory) in the inner tent. Large, highly positioned vents give excellent airflow and minimise 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. Mosquito netting in the flysheet doors keeps most insects out of the vestibule which is practical when cooking or if a four-legged friend is with you. The flysheet is made from Fjällräven’s new high-performance TripleRip nylon fabric. Its innovative construction combines two fabric weights for optimised strength/weight ratios; 40 denier at the top with 70 denier reinforcements at the bottom where abrasion from the ground is the highest. Just like all of Fjällräven’s tents, Keb Endurance 4 is made entirely without PVC plastic and toxic flame retardants, and the impregnation is fluorocarbon free.
