Sporting Goods
In rock climbing, nylon webbing is used in slings, runners, harnesses, anchor extensions and quickdraws. Webbing is used in many ways in hiking and camping gear including backpacks, straps, load adjusters and tent adjusters. There are two types of webbing: tubular and flat. The most popular webbing is one inch but it is available in two and three inch widths which in earlier days were often used in lieu of climbing harnesses. Wrapped around the waist several times, they were less bulky and more comfortable than the old school method of tying the rope around the waist. More elaborate configurations would include leg loops, which were essential to hold a climber who had fallen or otherwise found themselves dangling. If left supported only by rope or webbing wrapped around the waist, the diaphragm could be constricted and many climbers died as a result of asphyxiation. Narrower webbing is frequently looped through chockstones which are typically metal in shapes such as hexagonal, square, tubular, T, etc., and which are jammed into cracks as safety anchors. In other cases, webbing is looped over rock outcroppings. Unlike tubular rope, webbing is less likely to inch its way off the rock. Note that webbing construction is either utterly flat or flat-tubular; the latter tends to handle better but knots are more likely to jam. The most popular knots in webbing are the water knot and the grapevine knot. The latter is stronger, but uses more webbing for the knot. It is customary to leave a couple inches extending from the knot, and in many cases climbers tape the ends down onto the main loops. Webbing is also less expensive than rope of similar size particularly kernmantle rope which requires elaborate and expensive manufacturing. Unlike rope, which has manufacturers seeking brand identification and customer loyalty, webbing manufacture is typically generic. Climbing shops sell it off of a spool on a per yard or per foot basis. It is cut with a hot wire as is nylon rope, which prevents fraying and unravelling. However, when webbing does fray and unravel, the result is less disastrous than with rope, which is another albeit minimal advantage. Webbing suffers the drawback of less elasticity than perlon rope, and it may be more difficult to handle with gloves or mittens on.
Slacklines often use flat or tubular 1-inch webbing, or flat 2-inch webbing. Other widths are used, but are less common.

Famous quotes containing the words sporting and/or goods:
“The Boston papers had never told me that there were seals in the harbor. I had always associated these with the Esquimaux and other outlandish people. Yet from the parlor windows all along the coast you may see families of them sporting on the flats. They were as strange to me as the merman would be. Ladies who never walk in the woods, sail over the sea. To go to sea! Why, it is to have the experience of Noah,—to realize the deluge. Every vessel is an ark.”
—Henry David Thoreau (1817–1862)
“By right or wrong,
Lands and goods go to the strong.
Property will brutely draw
Still to the proprietor;
Silver to silver creep and wind,
And kind to kind.”
—Ralph Waldo Emerson (1803–1882)
