Learning from the past is important and I sometimes think about this from a design perspective. Can we learn from old traditional designs, or techniques and apply them to modern design? Is all primitive design and technology inferior? I believe that at the very least learning about old ways can provide us with food for thought, a comparison to our new directions and if necessary can inform any necessary adjustments to our course and design thinking. External frame backpacks are interesting not only of their more versatile modularity, but also because the structural component of the pack is clearly visible and offers a great opportunity to any designer wanting to explore structural innovation. Designing compelling structural elements from diverse materials such as wood, aluminium, or even carbon fiber is something I think most designers live to do. Every designer and their creativity draws from all forms of knowledge and inspiration, from the core to the fringes. From a footwear design perspective the compelling design of a soft shoe upper that is interchangeable from a structural sole could one day also be inspired from an external frame backpack. A potential design improvement on function, versatility and environmental impact. What follows is a short insight into some of the history of External Frame Backpacks. A reminder that although the external frame backpack was superseded by the internal frame almost 30 years ago, it is still a very functional piece of equipment and has an ancient history to prove it. It’s long history is also a very compelling reason to explore new ways to make it relevant again in today’s outdoor market. Although its unknown how long humans have been carrying packs on their backs, the first external frame backpack dates at least as far back as Őtzi, a shepherd who walked the Italo-Austrian Alps 5300 years ago. When we consider products over 100 years old to be antiques, its incredible to think that the external frame backpack has existed for over 53 centuries.
Via www.speerschleuder.de Since Őtzi load carrying frame structures have been documented in most of the world. In the fjords and isolated Norwegian valleys they were known as ‘Hjuringsmeis’, the ones below date back to the early 1800’s.
This Norwegian external frame backpack is called ‘Sekk med Meis’ and dates back to 1880. Via www.digitaltmuseum.no
The Russian traditional external frame pack is called “Ponyaga” or поняги was originally used by the Tungusic and Nivkh people from the far eastern Russian regions of Eastern Siberia and Khabarovsk Krai, the examples below are from Irkutsk.

Frame structures were also used by the First Nations people to carry loads across the American continent. But very little is written about them even though they are said to have inspired the design of one of the early commercial external frame packs, the Trapper Nelson backpack.

Exactly what the earliest mass produced external frame backpack was remains unclear. This frame below is from 1920, but does not include a pack.
But the first external frame backpack was probably patented by Colonel Henry C. Merriam in 1886. His invention provided soldiers with a light steel frame and hardwood sticks structure which transferred the weight of the pack to a belt above the buttocks. The frame reduced the pressure from the traditional crossed shoulder straps which typically caused pain to the chest on marches. The hardwood sticks then doubled up as a pole for a shelter tent.

Over 20 years later in 1908 Ole F. Bergans invented the metal frame rucksack and his Patent Nr. 20547 was registered in 1909. Ole F. Bergans believed that a backpack should be shaped according to a persons shape and height and should follow the form of the body. So using light tubular steel Ole F. Bergans bent a simple structure to follow the shape of the human back. The light tubular steel structure also made the pack more comfortable to carry as it prevented any awkwardly packed harder objects from making contact with the user’s back.
Below is an unusual version of the Bergans Pack made from wood maybe in a time when metal was too expensive, or maybe even an early prototype. The story behind the pack goes that in 1980 an older man went to the Bergans factory asking for a new bag to replace his old one. It was not customary to sell bags from the factory, so the manager referred him to the factory shop. But as soon as the manager saw the old bag, realizing it was one of the first Bergans products he changed his mind and replaced the old bag for a new one.
Lloyd F. “Trapper” Nelson’s 1920s reinforced pack board was also a notable patent and invention. Inspired by a Native American sealskin and willow stick pack, the new design emphasized ventilation for the back and also prevented hard objects in the pack from putting pressure on the users back.
Lloyd F. “Trapper” Nelson’s design would later also become known as the Alaskan Packboard.
Except on some military packboards which were made using plywood.

Although the design looks much older, Segen Packs an early environmentalist company from Eugene, OR made this backpack up until the 1980’s. Touted as a “Natural Pack, the founder Ed Segen stayed true to the use of classic natural materials of wood, canvas, leather and wool felt. But also adding some technical improvements like the modern designed hip belt.
The biggest leap in backpack development probably began in 1952 when Asher “Dick” Kelty and his wife Nena started the Kelty brand from their garage in Glendale, California. One of the biggest innovators in backpack design, Dick was not only one of the first to produce and market external-frame back packs specifically for civilian use, but Kelty is also considered to be the inventor of the rectangular aluminium framed backpack, the hip belt, using nylon, adding zippers to the pack pockets and the padded shoulder straps.
In 1952 after several years of making packs in his home garage for friends, Dick sold 29 packs in his first year of business for 24 dollars each. Dick hand-formed and welded each of the frames, and his wife, Nena, sewed each of the pack bags using WW II leftover parachute pack fabric. Kelty packs first include aircraft-aluminum contoured frames, padded shoulder straps, waist belts, clevis-pin attachment of pack bags, nylon pack cloth, zippered pockets, hold-open frames, and nylon back bands. The first shoulder straps were produced using wool carpeting for padding. The original clevis pins were made from aircraft rivets.
