Yeti was founded in East Germany near Berlin by Bernd Exner in 1983. His goal was to produce high quality outdoor equipment which would function under extreme conditions. He focused primarily on the manufacture of high-quality down sleeping bags and down clothing, believing they should offer the optimal protection in harsh weather. These fundamental conditions still remain an integral component of the Yeti-philosophy today.

The distinctive design elements of the Tuner, a sleeping bag weighing only 1,700 grams, are its integrated climate chambers, which facilitate flexible climate regulation for an improved micro-climate inside the sleeping bag. Heat accumulation is thus avoided, moisture immediately wicked away, and cooling prevented. Scientific tests have proven that deep sleep periods are extended by up to 20 per cent and an ultimately enhanced and calmer sleep results. The temperature range has likewise been extended: it spans from 20 to -1 degrees centigrade.
