cross-country skiing with expedition equipment

It has been a longstanding problem cross-country skiing with expedition equipment. Sleds are hard to pull uphill and dangerous downhill. Serious backache often occurs even after a few kilometers due to an exaggerated stooped forward posture. Balance Pockets balance the weight front and back allowing us to stand upright and carry all the weight in the pack without back pain. We can leave the sled at home and go ride the hills for a comfortable week of solitary skiing."
