DownTek™ Water Repellent Down Insulation

Down sleeping bag insulation has long been the favorite of backpackers, thru-hikers, and mountaineers due to its relative light weight and ability to pack down small. While down bags generally cost more and require more care to keep dry in humid conditions, the soft feel of down is unsurpassed and extremely popular.

What’s in a Name?

Located in the Lower Elk/Milner area west of Steamboat, Lake Windemere was formerly called Hitchens Lake after the pioneer Hitchens family who homesteaded the area. The Hitchens family ranch, known as Overlook Ranch, is recognized as one of a few centennial ranches in Routt County. Melvin "Hitch" Hitchens collected money from Routt County for allowing access across his land to the community dump west of Milner. And ultimately, he made more money by selling the dump (now the 'Milner Mall' landfill) to the current owner.
