You will be surprised but modern rucksacks are not carried on shoulders. Such rucksack has anatomical shape of the human's back the main job (up to 70% of the weight) falls on the pelvis thanks to the waistband, and only 30% of the weight - on the shoulders. It makes possibility to relieve of the spine. Experienced tourists walk the long distances with 40-50 kg rucksack. But don't be frightened! The weights of your rucksacks won't be more than 10-15 kg. And the main weight will be carried with Turkish mules, Karachai or Buryat horses, by Nepal Sherps, Chinese rickshaws, black mountain people Chaga from the slopes of Mt. Kilimanjaro or at last instructors of "Path Club".

The time of heavy tarpaulin tents covered with polyethylene is over. Modern two-ply tents weighs 3-4 kg & they are not perfectly blown through & waterproof. On the bottom of the tent a sleeping pad is put (such 1-1,5 cm thick sleeping pad is equal 1metre thick wood by its heat insulation). Then you are plunging into the soft & downy sleeping bag which keeps the warm of your body even the 20 degrees below zero out of door. So it is rather difficult to feel cold even you sleep only in the swimming trunks.
