In addition to their use in outdoors pursuits, backpacks are sometimes used in other sports as well. Hydration packs, sometimes used by athletes and military personnel, carry water (in either a bladder or a rigid bottle) and have a tube connected to them from which the wearer can drink without removing the pack; this feature is also included in some more general-purpose hiking backpacks. Backpacks that carry skateboards have also become more popular in the youth culture. https://i.pinimg.com/236x/d8/32/f8/d832f81e7862eb58f2a9e9a78c0182f0--bible-journal-hillbilly.jpg
Large backpacks, used to carry loads over 10 kilograms (22 lb), 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 stabilising 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 nearer the wearer's own center of mass.

Rolling backpacks are backpacks with wheels on the bottom and an extending handle. Because of their design, rolling backpacks reduce the strain on the user, though the shoulder straps may be used to carry the pack for short distances when the terrain is not suitable for wheels. Rolling backpacks are most commonly used while traveling by airplane or train. https://i.pinimg.com/236x/c0/55/ce/c055cebd7e3c24d8f3a19d5412ab7242--direct-sales-thirty-one.jpg
Sports and hydration backpacks are smaller with a profile closer to the body, wider straps and can come with water bladders and hip belts for running, cycling or hiking. Running hydration packs are the smallest and lightest, many under 2 litres and most under six litres. Compression straps across the top of one's body are common as are hip belts. Cycling hydration packs are six to ten litres sitting high on the back. Although daypacks are small averaging ten to thirty litres, all Trekking and Hiking hydration packs are generally the largest and heaviest. Thirty five up to sixty five litres and above are common. https://i.pinimg.com/236x/5e/d9/c2/5ed9c2b1a859ecaa02c112dd49beb2b6--younique-lip-liner-younique-makeup-looks.jpg
