External frame packs were designed to carry heavy loads (>20 kg or 40 lb), giving the wearer more support and protection and better weight distribution than a simple, frameless strapped bag. Wooden pack frames were used for centuries around the world. Ötzi the Iceman may have used one in Copper Age Alpine Italy, though some archaeologists believe the frame found with the body was part of a snowshoe. Such packs are common in military and mountaineering applications; metal versions first appeared in the mid-20th century. https://i.pinimg.com/236x/83/c1/1d/83c11dc93562477ce2adc391beb31033.jpg
Alternative names include haversack from the German Hafersack meaning "oat sack" (which more properly describes a small cloth bag on a strap worn over one shoulder and originally referred to the bag of oats carried as horse fodder), Kraxe (a German rucksack with a rigid framework), and bergen (a large load-carrying rucksack, from a design issued by the British Army during the Second World War). In fact, Britons used to call Alpine-style backpacks "Bergen rucksacks", maybe from the name of their creator, Norwegian Ole F. Bergan, combined with the name of the Norwegian city of Bergen. https://i.pinimg.com/236x/bc/6b/e8/bc6be89939405339827bccefb4539f1d--happy-sunday.jpg
Backpacks in general fall into one of four categories: frameless, external frame, internal frame, and bodypack. A pack frame, when present, serves to support the pack and distribute the weight of its contents across the body more appropriately, by transferring much of the weight to the hips and legs. Most of the weight is therefore taken off the shoulders, reducing the chance of injury from shoulder strap pressure (many backpacks equipped solely with shoulder straps can affect the posture of a person carrying more than 14 kg (30 lbs)), as well as being less restrictive of the upper body range of motion. Most backpacks are capable of being closed with either a buckle mechanism, a zipper, or a dry-bag type closure, though a few models use a drawstring fitted with a cord lock for the main compartment. https://i.pinimg.com/236x/f3/0d/e5/f30de5a9277708a6aec7bfec166b6511.jpg
Rolling backpacks are backpacks with wheels on the bottom and an extending handle. Because of their design, rolling backpacks reduce the strain on the user, though the shoulder straps may be used to carry the pack for short distances when the terrain is not suitable for wheels. Rolling backpacks are most commonly used while traveling by airplane or train. https://i.pinimg.com/originals/1b/88/cb/1b88cbd2e8b643b930ba210bf1f95899.jpg
The most popular time of the year for backpacks is the Back To School season. That's because school backpacks are the most common type of school bag among kids and college students alike. For versatility and value, you can't go wrong with a classic pack like the JanSport SuperBreak; it continues to be a top-rated best-seller year after year. Carrying a laptop across campus or during your commute? Choose a laptop backpack with dedicated compartments designed to keep your device secure and protected. Be sure to use our Laptop Bag Finder (found at the top left of every laptop bag page) to ensure your specific laptop model fits. Wheeled backpacks are also a great choice for students and even professionals who want to haul heavy loads without causing back strain. https://i.pinimg.com/236x/6f/5e/c0/6f5ec068b1e9a00b186f1e33114a1369.jpg
The external frame is typically made from aluminum, other lightweight metal alloy, and recently reinforced synthetic polymers or plastic and is equipped with a system of straps and tautly-stretched netting which prevents contact between the metal frame and user's back. In addition to comfort, this "stand-off" provides the additional benefit of creating air circulation between the frame and the wearer's back. For this reason, external frame packs are generally considered to be a "cooler load" than internal frame designs. External frame packs have a fabric "sack" portion which is usually smaller than that of internal frame packs, but have exposed frame portions above and below the sack to accommodate attachment of larger items. In addition, the sack can often be removed entirely, permitting the user to customize the configuration of their load, or to transport a non-conventional load such as a quartered game animal. Military packs are often external frame designs due to their ability to carry loads of different shapes, sizes and weights.

Sports and hydration backpacks are smaller with a profile closer to the body, wider straps and can come with water bladders and hip belts for running, cycling or hiking. Running hydration packs are the smallest and lightest, many under 2 litres and most under six litres. Compression straps across the top of one's body are common as are hip belts. Cycling hydration packs are six to ten litres sitting high on the back. Although daypacks are small averaging ten to thirty litres, all Trekking and Hiking hydration packs are generally the largest and heaviest. Thirty five up to sixty five litres and above are common. https://i.pinimg.com/236x/35/3b/8a/353b8a4a80781474e8f3132a0ae450fe.jpg
Typical school backpacks generally lack the rigid frame of an outdoor-style backpack and include only a few pockets in the front in addition to the main storage compartment. While traditionally very simple in design, school backpacks are often made with padded shoulder straps and backs as well as additional reinforcement to hold large numbers of heavy textbooks, as well as safety features such as reflective panels to make the wearer of the pack more visible at night. https://i.pinimg.com/236x/a7/d9/63/a7d9631ad9c39fe86d558a5788a01f1a--passion-parties-honeymoon-ideas.jpg

The simplest backpack design is a bag attached to a set of shoulder straps. Such packs are used for general transportation of goods, and have variable capacity. The simplest designs consist of one main pocket. This may be combined with webbing or cordage straps, while more sophisticated models add extra pockets, waist straps, chest straps, padded shoulder straps, padded backs, and sometimes reflective materials for added safety at night. These packs are generally produced inexpensively. https://i.pinimg.com/474x/f6/ea/81/f6ea81d1bf654dc06ce9ce2c532a0c75.jpg
