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?

Crosho Lake was and accidental discovery in 1882. The lake was discovered when a pair of early pioneers were looking for their lost horses while they were hunting for elk. When they became separated, one of the gentlemen reported finding a large herd of elk, while the other reported finding Crosho Lake. The horses gave them the slip permanently. Today, the area is popular for fishing and hiking on nearby trails. The Crosho Lake Recreation Area is located a few miles northwest of Yampa at the base of the Little Flat Tops. Hold onto your horses though, the area proves tempting for equines to go rouge.
