Tents: 2 x Hilleberg Soulo (we decided to carry one tent each to give ourselves personal space in the evenings.) These were superb in all weather. As the weather got warmer, we saved weight by switched to the Hillberg bivanorak which was just an incredible bit of kit – possibly our favourite of all!
Hiking Poles: Black Diamond. These were indispensable. They speed you up, help you keep your balance, and take 20% of pressure off your legs
Sleeping Bags: Mountain Hardwear Wraith -20 kept us alive during the cold winter. For the insulation it provides, it's really very light. As temeperatures increased, we switched to the Mountain Hardwear UltraLamina
Stove: MSR plus two fuel bottles and repair kit, plus titanium pan and spoon
