Una of the questions I get asked most in the shop is: \u201cWhat pack capacity do I need?\u201d<\/strong><\/p>\n

The doubt is usually the same: 30L, 40L, 50L or more? And many times the answer doesn\u2019t depend on how many days you\u2019re out, but on the real volume of your kit<\/strong> and how you use it.<\/p>\n

What really matters is the volume of your gear<\/strong> (and how much buffer you need for food, water, and weather changes).<\/p>\n

In this guide you\u2019ll see when a 30L<\/strong>, 40L<\/strong>, 50L<\/strong>, or 60L+<\/strong> pack makes the most sense, with a practical, realistic approach for hiking (and especially useful if you want to go lighter).<\/p>\n

The key rule<\/h2>\n

Trip length doesn\u2019t determine your pack. What actually takes up space is:<\/p>\n

    \n
  • Sleeping bag<\/strong> (often the bulkiest item)<\/li>\n
  • Sleeping pad<\/strong><\/li>\n
  • Shelter<\/strong> (tarp or tent)<\/li>\n
  • Clothing<\/strong> (especially in cold conditions or variable weather)<\/li>\n
  • Food<\/strong><\/li>\n
  • Water<\/strong> (depending on the route)<\/li>\n<\/ul>\n

    That\u2019s why you can do long routes with 40\u201350L<\/strong> packs if your gear is compact.<\/p>\n

    And the other way around: you might need 50\u201360L<\/strong> for just a few days if you\u2019re carrying a bulky bag or winter kit.<\/p>\n

    30-liter packs<\/h2>\n

    Who they\u2019re for<\/strong><\/p>\n

      \n
    • Day hikes<\/li>\n
    • Fast-and-light trips.<\/li>\n
    • Minimalists with ultralight, compact gear<\/li>\n
    • Mild, stable climates<\/li>\n<\/ul>\n

      When to choose 30L<\/strong><\/p>\n

        \n
      • You carry only the essentials and your kit packs down small<\/li>\n
      • You don\u2019t need bulky extra layers<\/li>\n
      • You don\u2019t usually carry much water or food<\/li>\n<\/ul>\n

        Typical limitation<\/strong>: very little buffer for weather shifts, multi-day food, or bulky items.<\/p>\n

        40-liter packs<\/h2>\n

        For many hikers, 40\u201345L<\/strong> is the sweet spot for ultralight backpacking.<\/p>\n

        Enough capacity for multi-day trips without hauling \u201cempty\u201d liters.<\/p>\n

        Who they\u2019re for<\/strong><\/p>\n

          \n
        • Multi-day trips<\/li>\n
        • Long-distance hiking with compact gear<\/li>\n
        • Typical 3-season use<\/li>\n<\/ul>\n

          When to choose 40L<\/strong><\/p>\n

            \n
          • Your kit is well optimized (or you\u2019re getting there)<\/li>\n
          • Your sleeping bag and pad aren\u2019t especially bulky<\/li>\n
          • You hike routes with fairly frequent resupplies<\/li>\n<\/ul>\n

            50-liter packs<\/h2>\n

            A 50\u201355L<\/strong> pack is usually the \u201cwith breathing room\u201d option without moving into expedition sizes.<\/p>\n

            It works really well if your kit isn\u2019t very compact yet, or if you want extra comfort by organizing things better.<\/p>\n

            Who they\u2019re for<\/strong><\/p>\n

              \n
            • Standard kit (not necessarily ultralight)<\/li>\n
            • More food between resupplies<\/li>\n
            • Routes where you need to carry more water<\/li>\n
            • Variable weather or more extra clothing<\/li>\n<\/ul>\n

              When to choose 50L<\/strong><\/p>\n

                \n
              • You don\u2019t want to be right at the limit for space<\/li>\n
              • You\u2019re carrying a slightly bulkier sleeping bag or clothing<\/li>\n
              • You want versatility across more types of routes<\/li>\n<\/ul>\n

                60-liter packs and above<\/h2>\n

                This capacity makes sense when you really<\/strong> need the extra volume.<\/p>\n

                For 3-season hiking, in many cases it\u2019s overkill.<\/p>\n

                Good for<\/strong><\/p>\n

                  \n
                • Winter or high mountains (more insulation, extra gear)<\/li>\n
                • Technical equipment (crampons, ice axe, rope, helmet)<\/li>\n
                • Expeditions or routes without resupply<\/li>\n
                • Very bulky gear or heavy loads<\/li>\n<\/ul>\n

                  How to choose your capacity (a practical method)<\/h2>\n

                  Before you buy, try this:<\/p>\n

                    \n
                  1. Lay out all your gear<\/strong> on the floor.<\/li>\n
                  2. Put it into a large bag or box to get a sense of the real volume<\/strong>.<\/li>\n
                  3. Add the volume of food<\/strong> (about 1\u20131.5L per day<\/strong>, depending on your diet and packaging).<\/li>\n
                  4. Factor in water<\/strong>: if the route has dry stretches, you\u2019ll need more capacity or better management.<\/li>\n<\/ol>\n

                    This method will give you a much more reliable estimate than thinking only in \u201cdays on trail.\u201d<\/p>\n

                    Conclusion<\/h2>\n

                    If you reduce the volume of your gear, you\u2019ll be able to use a smaller pack. And a smaller pack usually means:<\/p>\n

                      \n
                    • Less weight<\/strong> (from the pack itself)<\/li>\n
                    • Better stability<\/strong> and less sway<\/li>\n
                    • More simplicity<\/strong>: you carry what you need, not \u201cjust in case\u201d<\/li>\n<\/ul>\n

                      In ultralight hiking, the goal isn\u2019t to carry more\u2026 but to carry smarter<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
