A head sling from ancient times helps hikers carry heavy loads
Sometimes the best problem-solving technology already exists, as in the case of the tumpline. A new addition to Patagonia's line of hiking gear, the simple tumpline has been used for centuries by people needing to transport heavy equipment in undeveloped areas.
The sling attaches to heavy backpacks and by suspending it from your head, the tumpline more evenly distributes the weight, alleviating pressure on the hips, shoulders and back. While it takes time to get used to, it eases some pains of carrying a pack and promotes better posture overall.
