The internal frame backpack is a recent innovation, invented in 1967 by Greg Lowe, who went on to found Lowe Alpine and Lowepro, companies specializing in backpacks and other forms of carrying bags for various equipment.[8] An internal-frame pack has a large fabric section around an internal frame composed of strips of either aluminum, titanium or plastic, sometimes with additional metal stays to reinforce the frame. A complex series of straps works with the frame to distribute the weight and hold it in place. The internal frame permits the pack to fit closely to the wearer's back and minimizes shifting of the load, which is desirable when participating in activities that involve upper-body movement such as scrambling over rocky surfaces and skiing. However, the tight fit reduces ventilation, so these type of packs tend to be more sweaty than external frame packs. The internal construction also allows for a large storage compartment; a few lash points (including webbing loops and straps for sleeping bags and other large items) may be present, but as the frame is completely integrated, it is difficult to securely lash larger and heavier items which do not fit inside the compartment to the outside of the pack. Internal frame packs originally suffered from smaller load capacity and less comfortable fit during steady walking, but newer models have improved greatly in these respects. In addition, because of their snug fit, the improved internal frame models have largely replaced external frame backpacks for many activities. https://i.pinimg.com/236x/80/2c/db/802cdb5f816bdff8bc0ffc13a0744f42--travel-crafts-eagle-creek.jpg
Some backpacks are specifically designed to carry certain items. Common examples include backpacks for small valuable items such as laptops and cameras;[10] backpacks designed to hold laptop computers in particular generally have a padded compartment to hold the computer and medium-sized pockets and flaps to accommodate accessories such as charger cables and mice. These are especially common in college and university settings. In order to supply these devices with electricity, a few high-end backpacks are equipped with solar panels.[12] https://i.pinimg.com/236x/e2/23/a0/e223a0e331d6378c3246430d16664c98--thirtyone--party.jpg
The last item I received was the Key Fob. It makes it easy to just ‘throw’ my keys into my bag. It has a round key ring on one end and a clip on the other. I carry mine clipped to each other (the clip is clipped to the ring) to form a ‘bracelet’ to slip on my wrist if needed or to clip to my purse. My husband and I switch vehicles often, so it also makes it a lot easier to remove or attach the car or house keys. https://i.pinimg.com/236x/b3/35/f8/b335f886453b8b05b03e7cb19ac662f7.jpg
Many police tactical units, as well as players of military-style combat games such as paintball and airsoft, use these military-style tactical backpacks and webbing for storing gear and ammunition. There is also a small but thriving industry devoted to creating historical reproductions of military gear; such companies generally produce period-appropriate uniforms and other gear in addition to backpacks. https://i.pinimg.com/236x/29/ff/dc/29ffdccfc44812409e5a245f63e09b0a--thirty-one-products-thirty-one-gifts.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
