{"id":3179,"count":101,"description":"These backpacks are the appropriate capacity in volume (30-49 L) for typical overnight or minimalist two- to three-night backpacking trips. All these backpacks used an internal frame, some extremely minimal while others were quite substantial. We researched eight backpacks and chose these six, representing a broad range of design philosophies.\r\n\r\nOvernight packs, more than any other category of packs, are often used for multiple purposes; day hiking, backpacking, daily carry, climbing, and day touring ski trips, for a few examples. For multisport outdoor enthusiasts, the overnight pack is often the most-used in their quiver as it can serve as a jack of all trades. Choosing one pack to cover all potential uses is possible, but expect compromises.\r\n\r\nOvernight packs are often among the most popular in a brand\u2019s lineup and therefore dominate much of the development efforts. Suspension design tends to be at the forefront of development efforts. All the suspension designs profess load transfer to the hips while remaining comfortable. Suspension systems may employ proven designs such as the plastic frame sheet with aluminum stays, but advanced frame sheet and stay materials such as polycarbonate or carbon fiber are becoming more common. Some use tensioned mesh to ensure ventilation in the heat while others rely on channeling or raised components to hold the pack away from the body. Still others involve moving components to allow the pack to follow the body\u2019s natural movement patterns while hiking or scrambling. These packs have evolved an incredible amount since the advent of the internal frame backpack in 1967 by Greg Lowe, and this will persist as advancements continue in materials technology and understanding of human movement patterns. We expect improvements across all criteria to persist with a related reduction in weight.","link":"https:\/\/gearinstitute.com\/hiking\/hiking-camping-backpacks\/overnight-backpacks\/","name":"Overnight Backpacks (30-49 L)","slug":"overnight-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 Overnight Backpacks (30-49 L) | Reviews and Buying Advice | Gear Institute<\/title>\n<meta name=\"description\" content=\"Our experts extensively field-tested the best Overnight Backpacks (30-49 L) of the year and rated the best based on transparent, objective criteria.
