A tent is a shelter covered with sheets of cloth or other material and attached to pole frames or support ropes. Smaller tents may be freestanding or anchored to the ground, while larger tents are usually secured using drawstrings tied to stakes or tent pegs. Originally used as portable homes by nomads, tents are now more commonly used for recreational camping and temporary shelter.  

A waterproof bag is a flexible container that is sealed in a watertight manner. Waterproof bags are commonly used for kayaking, canoeing, rafting, canyoning, and other outdoor activities where delicate items get wet, as well as extreme sports like skiing and snowboarding. Dry bags are used to protect electronics from water. They are also used to keep sleeping bags and spare clothing from getting wet, such as in a camping environment.  

Seamless underwear has no visible seams that can cause discomfort and affect your well-fitting garment. This style of panty is usually made from a Lycra cotton blend that sits flat against the skin and wicks away sweat and moisture. They're gentle on the skin and fun to wear!  

Waterproof shoes feature a lining like Gore-Tex that keeps water from getting inside the shoe and soaking your feet, unlike traditional running shoes that have an ultralight mesh upper. Water resistance provides the best support and traction in mud, rain and snow.  

Medical protective clothing has good moisture permeability and barrier properties, and can effectively resist the penetration of alcohol, blood, body fluids, air dust particles, and bacteria. It is safe and convenient to use, and can effectively protect the wearer from the threat of infection. Comfortable to wear, good hand feeling, strong tensile strength, breathable and waterproof, no cross-infection, etc.  

Diving suits are diving supplies, which are used to prevent excessive body temperature loss during diving, resulting in hypothermia, and can also protect divers from reefs or harmful animals and plants.  

Waterproof gloves and mittens are often used in cold and wet conditions. When used properly, they protect your fingers and keep your hands dry and warm on and off the track. Wearing waterproof gloves and/or mittens is extremely important when hiking in the mountains, as the weather at high altitudes often changes quickly. In very cold conditions, even insulated waterproof gloves may not be enough to keep your hands warmth.  

The classic layered clothing system consists of three or more layers. Each of them has its specific function. For example, inner layers, also known as base layers, are designed to wick moisture away from the body, disperse it to prevent colds, and efficiently transport moisture to the outer surface of the garment. The second layer, called the middle layer, has one main function, which is to prevent the loss of body heat by trapping air and providing insulation, while the main task of the outer layer is to protect the other two layers from the elements. It is important to emphasize that sometimes this classification can be misleading. Remember, there are so many different circumstances and conditions, so take everything with a grain of salt. To be able to cope with changing conditions, don't be afraid to make adjustments (try mixing and matching various hiking clothing).
