The Keron Tent quickly became Hilleberg's flagship tent when it was first introduced in 1981, and the design has been testedon countless expeditions on both the North and South poles, Greenland, the South Patagonian Icecap, and the often ice locked Northern tundra of Sweden ever since. It must have passed the tests, because little has changed on the Keron over the years. But while its basic design remains the same, Hilleberg has kept the tent relevant by incorporating modern fabrics and other material advancements through the years, so things aren't quite the same as they were 35 years ago. What's the same' Hilleberg has made sure the Keron's maintained the same space maximizing tunnel shape, convenient dual door construction, and easy to set up design. Both the outer tent and inner tent are linked for faster pitching in windy environments, while the dual vestibules maximize storage space for gear, so you don't have to cuddle up with your soggy pack and smelly boots . Made with Hilleberg's Black Label construction, the Keron is composed of top shelf fabrics and components to ensure solid and reliable performance in the harshest alpine and arctic environments. The outer fabric is Hilleberg's proprietary Kerlon 1800 high tenacity nylon, which has been coated on both sides with a silicone coating to give the outer tent a hydrostatic head rating of 3000mm. The bathtub floor extends along the sides of the inner tent to prevent ground water from seeping through and is triple coated with a PU treatment, making it more than three times more waterproof than the fly to seal out standing water.It's fairly basic in design, which means there's less to go wrong, but the Keron has all the features necessary to make it a comfortable shelter in the most demanding environments. Both the mesh backed doors and adjustable no see um mesh vents located on both vestibules can be adjusted to dial in the necessary ventilation to prevent condensation from accumulating along the tent wall...
