Rucksacks: 2 x Osprey Argon 85 litre. Comfortable, large, and had a cool pouch on the back and side which we kept the video camera and tripod in. We also took the raincover for the summer which was excellent. The Osprey Hydraform Reservoir was great for keeping us hydrated, especially in the summer.
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!
Rollmats: Originally went with Pacific Outdoor inflatation mats, but in the extreme lows of the Gobi Winter we discovered inflatable mats were not ideal (the air inside becomes cold, and transfers that to your body.) We switched to Thermarest closed cell mats, which did a great job.
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
First Aid Kit – with plasters, various antibiotics, laxative, immodium, and serious painkillers.
