{"id":3178,"count":51,"description":"There is nothing more central to the backpacking experience than a hiker\u2019s pack. This relationship is central and nothing can end any trip earlier than a poorly-performing backpack. It\u2019s pretty hard to get excited about walking 40 more miles when your back already hurts after the first 4 miles on the trail.\r\n\r\nDuring the course of testing these packs saw use on dozens, if not hundreds, of trail miles including at least one trip of four or more days. Over our years of pack testing, it has become increasingly clear that pack specialization is a growing trend. As ultralight backpacking gets more popular, all backpacking gear \u2013 including packs \u2013\u00a0gets smaller and lighter. Ten years ago, a PCT thru-hiker would usually select a 70-liter pack for their trek, while today they might get away with a 50-liter pack. So the packs that were specialized to the mountain environment are getting more specialized, and the trail-specific packs are developing more goodies to make the packs more applicable in a mountain environment, such as the Osprey Aether Pro, which, by all accounts is a very light thru-hiking pack, but can also carry a pair of skis, instantly opening the range of possible missions where you could use it.\r\n\r\n<img class=\"alignright size-medium wp-image-37247\" src=\"https:\/\/gearinstitute.com\/wp-content\/uploads\/Gregory_Baltoro75_21-Credit-Gregory-Will-Saunders-900x514.jpg\" alt=\"\" width=\"900\" height=\"514\" \/>","link":"https:\/\/gearinstitute.com\/hiking\/hiking-camping-backpacks\/expedition-backpacks\/","name":"Expedition Backpacks (70+ L)","slug":"expedition-backpacks","taxonomy":"category","parent":3176,"meta":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>The Best Expedition Backpacks (70+ L) | Reviews and Buying Advice | Gear Institute<\/title>\n<meta name=\"description\" content=\"Our experts extensively field-tested the best Expedition Backpacks (70+ L) of the year and rated the best based on transparent, objective criteria.
