In cold climates, a thick knitted scarf (sometimes known as a "muffler"), often made of wool, is tied around the neck to keep warm. This is usually accompanied by a heavy jacket or coat. Also, the scarf could be used to wrap around the face and ears for additional cover from the cold.

In drier, dustier warm climates, or in environments where there are many airborne contaminants, a thin headscarf, kerchief, or bandanna is often worn over the eyes and nose and mouth to keep the hair clean. Over time, this custom has evolved into a fashionable item in many cultures, particularly among women. The cravat, an ancestor of the necktie and bow tie, evolved from scarves of this sort in Croatia.

Scarves that are used to cover the lower part of face are sometimes called a cowl. Scarves can be colloquially called a neck-wrap.

Scarfs can be tied in many ways including the pussy-cat bow, the square knot, the cowboy bib, the ascot knot, the loop, the necktie, and the gypsy kerchief. Scarfs can also be tied in various ways on the head.

Backpacking, recreational activity of hiking while carrying clothing, food, and camping equipment in a pack on the back. Originally, in the early 20th century, backpacking was practiced in the wilderness as a means of getting to areas inaccessible by car or by day hike. It demands physical conditioning and practice, knowledge of camping and survival techniques, and selection of equipment of a minimum weight consistent with safety and comfort. In planning an excursion, the backpacker must take into consideration food and water, terrain, climate, and weather.

Packs hang from the shoulders or are supported by a combination of straps around shoulders and waist or hips. Types range from the frameless rucksack, hung from two straps, and the frame rucksack, in which the pack is attached to a roughly rectangular frame hung on the shoulder straps, to the contour frame pack, with a frame of aluminum or magnesium tubing bent to follow the contour of the back.

The Kelty-type pack, which is used with the contour frame, employs a waistband to transfer most of the weight of the pack to the hips.

A sun hat is a head covering specifically designed to shade the face and shoulders from the sun. The sun hat incorporates a variety of materials and types, including the straw sun hat, pressed fiber sun hat, and the pith helmet (sun helmet). In modern times, sun hats are common in places around the world, mainly in holiday resorts residing in countries close to the Earth's equator. They are particularly useful in protecting against ultraviolet rays (UV). The style of a sun hat can range from small to large brims. However, as a general guideline, the brim is four to seven inches in width.

Modern materials have revolutionized backpack construction, utility, and capacity.

The earliest packs were made from canvas, which, while strong and durable, added considerable weight for the backpacker to manage and lacked resistance to the elements. Today’s packs are constructed of nylon or similar lightweight materials and are usually at least partially waterproof.

Clothing is weatherproof and insulating, including shell parkas, insulating underwear, down clothing, windpants, ponchos, sturdy waterproof boots with soles designed for maximum traction, and heavy socks. Tents may be a simple tarpaulin, a plastic sheeting tube, or a two-person nylon mountain tent. Sleeping bags of foam, dacron, or down and air mattresses or foam pads may be carried. Lightweight pots and pans and stoves are specially designed for backpacking; dehydrated food provides stew-type one-pot dishes.

Backpackers must be able to read topographic maps and use a compass; they must also carry emergency food and first-aid equipment and be acquainted with survival techniques.

In the later 20th century, backpacking became associated with travel, especially by students, outside the wilderness.
