Packing for a through-hike is different from packing for a weekend trip, because your bag becomes your home for weeks or months. Every item needs a fixed place, so you can find things in the dark, in rain, or when you are tired. A good packing system also protects your body: weight carried close to your back and at hip height feels lighter and keeps you balanced on uneven trail. Spend time getting the system right before you start, and it will pay off every single day.

Begin with the sleeping bag at the bottom of the pack, in a waterproof stuff sack or a pack liner. It is the item you need last each day, and it benefits from the cushioning of sitting at the base. Above it, pack your spare clothes and any soft items, which fill gaps and create a stable platform. The heaviest items, usually food, the stove, and water, go in the middle of the pack and close to your back, roughly between your shoulder blades. This keeps the centre of gravity near your body and stops the pack pulling you backwards.

The top of the pack is for things you need during the day or first at camp: the rain jacket, a warm layer, the first aid kit, and the tent or shelter if you pack it separately. Use the hip belt pockets for small essentials you reach for constantly, such as snacks, lip balm, a phone, and a small knife or multitool. Side pockets hold water bottles and a water filter. Anything strapped to the outside should be secured tightly, because loose items snag on branches, get lost, and throw off your balance.

Waterproofing is essential on a long trail. A pack cover helps, but rain often finds its way in through seams and openings, so line the inside of your pack with a large plastic bag or a dedicated liner, and keep critical items like electronics and your sleeping bag in their own dry bags. Organise small items in zip bags or tiny stuff sacks by category: repair kit, toiletries, electronics, and food. Clear organisation means you stop unpacking everything to find one item, which saves time and frustration at every stop.

Resupply days are part of the packing routine. When you pick up food, repack it immediately: remove cardboard boxes and excess packaging, combine similar items, and put the heaviest food in the centre of the pack. Plan which meals you will eat first, and place the first day of food where it is easiest to reach. Keep a small bag for rubbish, and empty it at every town stop. Weigh your pack after resupply, because a few heavy luxury items can creep in at town stops and make the next stretch harder than it needs to be.

Finally, adjust the pack to your body every morning. Tighten the hip belt first so most of the weight sits on your hips, then the shoulder straps, then the load lifters that pull the top of the pack toward you. The chest strap stops the shoulder straps sliding off. If something hurts after an hour, stop and adjust rather than pushing through, because small discomforts become injuries over hundreds of kilometres. A well-packed bag should feel like part of you, not a burden you drag along the trail.

As the weeks pass, your packing system will evolve, and that is a good thing. Items migrate to new pockets, some gear gets sent home from trail towns, and a few comfort items earn their place permanently. Keep a small notebook or phone note listing your current packing order, so after a town stop you can rebuild the system exactly rather than guessing. Consistency is what makes a through-hike bag feel effortless, even after hundreds of kilometres on the trail.
