Internal Frame Pack
A backpack, also called knapsack, schoolbag, rucksack, pack, booksack, bookbag, haversack, packsack, or backsack, is in its simplest frameless form, a fabric sack carried on one's back and secured with two straps that go over the shoulders; but it can have an external or internal frame, and there are bodypacks. Backpacks are commonly used by hikers and students, and are often preferred to handbags for carrying heavy loads or carrying any sort of equipment, because of the limited capacity to carry heavy weights for long periods of time with hands. Large backpacks, used to carry loads over , 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 stabilizing 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 n ...

Snowshoe
Snowshoes are specialized outdoor gear for walking over snow. Their large footprint spreads the user's weight out and allows them to travel largely on top of rather than through snow. Adjustable bindings attach them to appropriate winter footwear. Traditional snowshoes have a hardwood frame filled in with rawhide (material), rawhide latticework. Modern snowshoes are made of lightweight metal, plastic, and other synthetic materials. In the past, snowshoes were essential equipment for anyone dependent on travel in deep and frequent snowfall, such as Animal trapping, fur trappers. They retain that role in areas where motorized vehicles cannot reach or are inconvenient to use. However, their greatest contemporary use is for recreation. Snowshoeing is easy to learn and in appropriate conditions is a relatively safe and inexpensive recreational activity. However, doing so in icy, steep terrain requires both advanced skill and mountaineering-style pivoting-crampon snowshoes. Devel ...

Copper Age
The Chalcolithic ( ) (also called the Copper Age and Eneolithic) was an archaeological period characterized by the increasing use of smelted copper. It followed the Neolithic and preceded the Bronze Age. It occurred at different periods in different areas, but was absent in some parts of the world, such as Russia, where there was no well-defined Copper Age between the Stone and Bronze Ages. Stone tools were still predominantly used during this period. The Chalcolithic covers both the early cold working (hammering) of near pure copper ores, as exhibited by the likes of North American Great Lakes Old Copper complex, from around 6,500 BC, through the later copper smelting cultures. The archaeological site of Belovode, on Rudnik mountain in Serbia, has the world's oldest securely dated evidence of copper smelting at high temperature, from . The transition from Copper Age to Bronze Age in Europe occurred between the late 5th and the late In the Ancient Near East the Copper Ag ...

Ă–tzi The Iceman
Ă–tzi, also called The Iceman, is the natural mummy of a man who lived between 3350 and 3105 BC. Ă–tzi's remains were discovered on 19 September 1991, in the Ă–tztal Alps (hence the nickname "Ă–tzi", ) at the Austria–Italy border. He is Europe's oldest known natural human mummy, offering an unprecedented view of Chalcolithic (Copper Age) Europeans. Because of the presence of an arrowhead embedded in his left shoulder and various other wounds, researchers believe that Ă–tzi was killed by another person. The nature of his life and the circumstances of his death are the subject of much investigation and speculation. His remains and personal belongings are on exhibit at the South Tyrol Museum of Archaeology in Bolzano, South Tyrol, Italy. Discovery Ă–tzi was found on 19 September 1991 by two German tourists, at an elevation of on the east ridge of the Fineilspitze in the Ă–tztal Alps on the Austrian–Italian border, near Similaun mountain and the Tisenjoch pass.

Mountaineering
Mountaineering, mountain climbing, or alpinism is a set of outdoor activities that involves ascending mountains. Mountaineering-related activities include traditional outdoor climbing, skiing, and traversing via ferratas that have become mountain sports, sports in their own right. Indoor climbing, sport climbing, and bouldering are also considered variants of mountaineering by some, but are part of a wide group of mountain sports. Unlike most sports, mountaineering lacks widely applied formal rules, regulations, and governance; mountaineers adhere to a large variety of techniques and philosophies (including grade (climbing), grading and climbing guidebook, guidebooks) when climbing mountains. Numerous local alpine clubs support mountaineers by hosting resources and social activities. A federation of alpine clubs, the International Climbing and Mountaineering Federation (UIAA), is the International Olympic Committee-recognized world organization for mountaineering and climbing.

Ultralight Backpacking
Ultralight backpacking (sometimes written as UL backpacking) is a style of lightweight backpacking (wilderness), backpacking that emphasizes carrying the lightest and least amount of gear. While no technical standards exist, some hikers consider "ultralight" to mean an initial base weight of less than . Base weight is the weight of a fully loaded backpack at the start of a trip, excluding worn weight and consumables such as food, water, and fuel (which vary depending on the duration and style of trip). Base weight can be lowered by reducing the weight of individual items of gear, or by choosing not to carry that gear. Ultralight backpacking is popular among Thru-hiking, thru-hikers. In the United States, the terms "light" and "ultralight" often refer to backpackers who carry gear with a base weight below respectively. These weights are more easily achievable for smaller hikers. Larger hikers may need to carry clothes, shelters, sleep systems and backpacks that weigh up to 50% more ...

Rope
A rope is a group of yarns, Plying, plies, fibres, or strands that are plying, twisted or braided together into a larger and stronger form. Ropes have high tensile strength and can be used for dragging and lifting. Rope is thicker and stronger than similarly constructed cord, String (structure), string, and twine. Construction Rope may be constructed of any long, stringy, fibrous material (e.g., rattan, a natural material), but generally is constructed of certain natural fibre, natural or synthetic fibre, synthetic fibres. Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be made to float on water. But synthetic ropes also possess certain disadvantages, including slipperiness, and some can be damaged more easily by UV light. Common natural fibres for rope are Manila hemp, hemp, linen, cotton, coir, jute, straw, an ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cord Lock
A plastic cord lock (also known as cord fastener, plastic stopper, spring clasp or cord toggle) attaches to drawstrings and tightens without the use of knots. Cord locks allow mountaineers to fasten clothing and camping equipment quickly in cold conditions when the fingers are encased in heavy gloves. They consist generally of three parts: a barrel, a toggle (plunger), and a spring. Squeezed together, tension is released and the cord lock can move freely up and down the cords. Released, the tension is engaged and the cord lock stays in place. They come in many sizes and shapes to suit to any purpose, including plastic cord lock, mini size cord lock, no spring cord lock, with spring cord lock, with rim cord lock. Cord fasteners are used in many different applications to retain one or more cord segments or drawstrings in a tightened condition and to release such cord segments when desired. For example, cord locks are used in connection with garments that include drawstrings, such a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Zipper
A zipper (N. America), zip, zip fastener (UK), formerly known as a clasp locker, is a commonly used device for binding together two edges of textile, fabric or other flexible material. Used in clothing (e.g. jackets and jeans), luggage and other bags, camping gear (e.g. tents and sleeping bags), and many other items, zippers come in a wide range of sizes, shapes, and colors. In 1892, Whitcomb L. Judson, an American inventor from Chicago, patented the original design from which the modern device evolved. The zipper gets its name from a brand of rubber boots (or galoshes) it was used on in 1923. The galoshes could be fastened with a single zip of the hand, and soon the hookless fasteners came to be called "Zippers". Description A zipper consists of a slider mounted on two rows of metal or plastic teeth that are designed to interlock and thereby join the material to which the rows are attached. The slider, usually operated by hand, contains a Y-shaped channel that, by moving alon ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Buckle
A buckle or clasp is a device used for fastening two loose ends, with one end attached to it and the other held by a catch in a secure but adjustable manner. Often taken for granted, the invention of the buckle was indispensable in securing two ends before the invention of the zipper. The basic buckle frame comes in a variety of shapes and sizes depending on the intended use and fashion of the era.Meredith, Alan and Gillian. (2008). ''Buckles''. Oxford: Shire Library. pg. 5. Buckles are as much in use today as they have been in the past: used for much more than just securing one's belt, instead they are one of the most dependable devices in securing a range of items. The word "buckle" enters Middle English via Old French and the -4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... and the Latin ''buccula'' or "cheek-strap," as for a helmet.
