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/a0/a6/bd/a0a6bdb99d61a5af2054e911b3e2ea76--pure-romance.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/fe/96/e7/fe96e7a5c14d871803b3f6d67951acd0--shaving-cream.jpg
Large backpacks, used to carry loads over 10 kilograms (22 lb), as well as smaller sports backpacks (e.g. running, cycling, hiking and hydration), usually offload the largest part (up to about 90%) of their weight onto padded hip belts, leaving the shoulder straps mainly for stabilising the load. This improves the potential to carry heavy loads, as the hips are stronger than the shoulders, and also increases agility and balance, since the load rides nearer the wearer's own center of mass. https://i.pinimg.com/236x/81/8d/45/818d45c8d48ce1857e20a29fa8bfa10d---gifts-thirty-one-gifts.jpg

I actually use this tote as a diaper bag, I have two children in diapers and it really works great for that. Aside from the way I use it, I think it's an over all great bag. A few issues: the elastic pockets on the sides seem to have lost their tension already, I don't put anything large or heavy in them to cause this, also the pocket in the back.. Wish it was larger, I don't really see the point of the zipper in the bottom of the pocket. The only other issue I have is the straps, wish they had some sort of padding on them, they tend to be a little hard on your hands if you're carrying anything heavy. https://i.pinimg.com/236x/b1/2d/12/b12d12c86b9b97c78ad722508d1cd2bd.jpg?b

In addition to their use in outdoors pursuits, backpacks are sometimes used in other sports as well. Hydration packs, sometimes used by athletes and military personnel, carry water (in either a bladder or a rigid bottle) and have a tube connected to them from which the wearer can drink without removing the pack; this feature is also included in some more general-purpose hiking backpacks. Backpacks that carry skateboards have also become more popular in the youth culture. https://i.pinimg.com/originals/db/54/e3/db54e3e7683789b29dce47450c786de9.jpg
The other type of external frame which recently was proposed, is made from composite plastic which is not flexible like current backpack straps and also it is a kind of material that can be shaped like human spine curvature. In this type of backpack, load directly transfers to the shoulders through the non-flexible straps. This non-flexible structure diminishes the momentum at lumbar region of the back. Strap curvature is shaped close to spine curvature and there are two flexible drawstrings to prevent backpack movement in transverse plane. The straps of this backpack are wide enough to distribute the pressure on shoulders and also a white glass wool layer is added to the internal part of them to absorb dynamic forces, which could be produced through walking. This backpack type is an experimental sample that need further options to be prepared for usage. One of the benefits of backpack with external frame is preventing the spine to incline forward during walking that would be helpful in preventing damage of long term backpack carrying.[4] https://i.pinimg.com/236x/85/54/1b/85541b9681a49a5d3a5a658040044ff9.jpg

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,[5][6] though some archaeologists believe the frame found with the body was part of a snowshoe. Such packs are common in military and mountaineering applications;[7] metal versions first appeared in the mid-20th century. https://i.pinimg.com/236x/98/68/18/98681863441d4f190fcf5e2b8a4e403a.jpg
Hiking backpacks and backpacking packs are the only choice for carrying your gear on the trail regardless if you're on a casual day hike or a serious backcountry expedition. Similarly, hydration backpacks from brands like CamelBak, are ideal for staying hydrated outdoors on hikes, runs, and bike rides. There are even winter hydration backpacks that are insulated to keep water from freezing in cold temperatures. Travel backpacks offer storage for travel essentials plus handy features that help keep travelers on the move like wheels and detachable daypacks. They remain a popular style carried by students abroad and the jet-set crowd. https://i.pinimg.com/236x/c3/ce/42/c3ce42719a04df78075be1078d29794a--thirty-one-uses--uses-for-thirty-one-products.jpg?b

Alternative names include haversack from the German Hafersack meaning "oat sack"[1] (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).[2] 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.[citation needed] https://i.pinimg.com/originals/c1/d7/50/c1d750411a73750178e06d446be6b92d.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
