Quick answer: walking hut to hut, a 50 to 58 litre pack is plenty, and the Osprey Exos 58 is light enough that you barely notice it. Camping with a tent, go to 65 litres and pick the Osprey Atmos AG 65 for its comfortable suspended back. Either way, line it with a dry bag.

How big a pack for a Great Walk?

Because Great Walk huts provide mattresses and most have gas cookers, a hut walker carries surprisingly little: sleeping bag, clothes, rain gear, a small cook kit and food for three or four days. That fits in 45 to 55 litres. Booked into campsites instead, you add a tent, a sleeping mat and a stove, and 60 to 65 litres makes life easier. Food is the variable: four days of dinners and breakfasts takes more space than people expect.

The picks

Best for hut-to-hut walkers

Osprey Exos 58 Backpack

An ultralight pack with a ventilated mesh back panel and enough frame to carry a full Great Walk load comfortably. Ideal when the huts take care of your bed.

  • Light pack weight, so more of your load is food and clothing
  • Ventilated back for humid bush sections
  • Women's version is the Osprey Eja

Skip it if: you are carrying a tent and heavy camping gear. Its frame prefers moderate loads.

Best for campers and heavy loads

Osprey Atmos AG 65 Backpack

Osprey's Anti-Gravity suspension wraps a tensioned mesh panel around your back and hips, spreading heavy loads better than most packs. The one to choose if you are camping or carrying for two.

  • Very comfortable with 15 kg and more
  • Adjustable fit
  • Women's version is the Osprey Aura AG

Skip it if: weight is your priority. It is heavier than the Exos.

The pack liner: the cheapest insurance you will buy

Essential

Sea to Summit Lightweight Dry Bag

A roll-top waterproof bag that goes inside your pack. Put your sleeping bag and hut clothes in it. If everything else gets wet, those stay dry, and that is what gets you through a wet night.

  • Pick a size that fits your sleeping bag plus a set of clothes
  • Light, and it doubles as a food or clothes bag in the hut
