A dry bag is a type of flexible container which seals in a watertight manner. Dry bags are often used in kayaking, canoeing, rafting, canyoning, [1] and other outdoor activities in which sensitive items would otherwise get wet, as well as extreme sports such as skiing and snowboarding. Dry bags are used to protect electronics from water. They are also used to prevent sleeping bags and spare clothing from getting wet, as in a camping context.
They are often a construction of plastic film, plastic-coated fabric, or waterproof fabric ( Nylon, Vinyl, TPU, PVC and Tarpaulin )which is formed to create an impermeable, waterproof bag. Construction techniques include welding,(RF or Radio Frequency Welding) sewing (a seam-tape is used to seal over any needle holes) and gluing.
A large range of sizes are available, ranging from small bags large enough for a camera or smartphone to mid-size bags large enough for a sleeping bag, to large bags big enough for several sleeping bags and a folded tent.
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.
A tent is a shelter consisting of sheets of fabric or other material draped over or attached to a frame of poles or a supporting rope. While smaller tents may be free-standing or attached to the ground, large tents are usually anchored using guy ropes tied to stakes or tent pegs. First used as portable homes by nomads, tents are now more often used for recreational camping and as temporary shelters.
A sleeping bag is an insulated covering for a person, essentially a lightweight quilt that can be closed with a zipper or similar means to form a tube, which functions as lightweight, portable bedding in situations where a person is sleeping outdoors. It is also commonly used indoors for people who do not have beds or at sleepovers. Its primary purpose is to provide warmth and thermal insulation through its synthetic or down insulation. It also typically has a water-resistant or water-repellent cover that protects, to some extent, against wind chill and light precipitation, but a tent is usually used in addition to a sleeping bag, as it performs those functions better. The bottom surface also provides some cushioning, but a sleeping pad or camp cot is usually used in addition to that purpose. The bottom surface of a sleeping bag may be moderately water repellent, but a plastic tarp or groundsheet is often used to protect against moist ground.
A dry suit or drysuit provides the wearer with environmental protection by way of thermal insulation and exclusion of water, and is worn by divers, boaters, water sports enthusiasts, and others who work or play in or near cold or contaminated water. A dry suit normally protects the whole body except the head, hands, and possibly the feet. In hazmat configurations, however, all of these are covered as well.
A zipper, zip, zip fastener (UK), formerly known as a clasp locker, is a commonly used device for binding together two edges of fabric or other flexible material. Used in clothing, luggage and other bags, camping gear, 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.
A pannier is a basket, bag, box, or similar container, carried in pairs either slung over the back of a beast of burden, or attached to the sides of a bicycle or motorcycle. The term derives from a Middle English borrowing of the Old French panier, meaning 'bread basket'.
Lamination is the technique/process of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, sound insulation, appearance, or other properties from the use of the differing materials, such as plastic. A laminate is a layered object or material assembled using heat, pressure, welding, or adhesives. Various coating machines, machine presses and calendering equipment are used.
Earthbag construction is an inexpensive building method using mostly local soil to create structures which are both strong and can be quickly built.
A plastic bag, poly bag, or pouch is a type of container made of thin, flexible, plastic film, nonwoven fabric, or plastic textile. Plastic bags are used for containing and transporting goods such as foods, produce, powders, ice, magazines, chemicals, and waste. It is a common form of packaging.
A paper bag is a bag made of paper, usually kraft paper. Paper bags can be made either with virgin or recycled fibres to meet customers' demands. Paper bags are commonly used as shopping carrier bags and for packaging of some consumer goods. They carry a wide range of products from groceries, glass bottles, clothing, books, toiletries, electronics and various other goods and can also function as means of transport in day-to-day activities.
Hessian, burlap in North America, or crocus in Jamaica and the wider Caribbean, is a woven fabric made of vegetable fibres, usually the skin of the jute plant or sisal leaves. It is generally used for duties of rough handling, such as making sacks employed to ship farm products and to act as covers for sandbags, and for wrapping tree-root balls. However, this dense woven fabric, historically coarse, more recently is being produced in a refined state, known simply as jute, as an eco-friendly material for bags, rugs, and other products.
A bivouac shelter or bivvy is any of a variety of improvised camp site or shelter that is usually of a temporary nature, used especially by soldiers or people engaged in backpacking, bikepacking, scouting or mountain climbing. It may often refer to sleeping in the open with a bivouac sack, but it may also refer to a shelter constructed of natural materials like a structure of branches to form a frame, which is then covered with leaves, ferns and similar material for waterproofing and duff for insulation. Modern bivouacs often involve the use of one- or two-person tents but may also be without tents or full cover. In modern mountaineering the nature of the bivouac shelter will depend on the level of preparedness, in particular whether existing camping and outdoor gear may be incorporated into the shelter.
A silo is a structure for storing bulk materials.
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system. It is distinguished from air purifiers, which use disposable filters to remove dust.
Nonwoven fabric or non-woven fabric is a fabric-like material made from staple fibre (short) and long fibres, bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. Some non-woven materials lack sufficient strength unless densified or reinforced by a backing. In recent years, non-wovens have become an alternative to polyurethane foam.
Hiking equipment is the equipment taken on outdoor walking trips. The duration, distance, planned activities, and environment impacts equipment selection. For example, a short day hike across flat farmland versus trekking in the Himalayas would call for different types of equipment.
A single-serve coffee container is a container filled with coffee grounds, used in coffee brewing to prepare only enough coffee for a single portion. Single-serve coffee containers come in various formats and materials, often either as hard and soft pods or pads made of filter paper, or hard aluminium and plastic capsules.
Golf equipment encompasses the various items that are used to play the sport of golf. Types of equipment include the golf ball, golf clubs, and devices that aid in the sport.
A bag is a common tool in the form of a non-rigid container, typically made of cloth, leather, bamboo, paper, or plastic. The use of bags predates recorded history, with the earliest bags being lengths of animal skin, cotton, or woven plant fibers, folded up at the edges and secured in that shape with strings of the same material. Bags can be used to carry items such as personal belongings, groceries, and other objects. They come in various shapes and sizes, often equipped with handles or straps for easier carrying.
Pollination bags, sometimes called crossing bags, isolation bags or exclusion bags, are containers made of various different materials for the purpose of controlling pollination for plants.
