I just wanted to thank SOS for your support on our recent expeditions. We used SOS on expeditions to Cho Oyu, Ama Dablam, Himlung, Three Peaks of Nepal and Island Peak in the Himalaya, plus Carstensz Pyramid in West Papua. Our guides and climbers loved the sachets, finding the serving size perfect for rehydrating on the go and very lightweight compared to other products which is obviously key to expeditions such as these. SOS was a particular hit on the arduous jungle trek out from Carstensz Pyramid; 12 hour days through humid jungle, mud and swamps means that hydration is paramount and SOS definitely served us well in this regard! We are looking forward to using SOS on future expedition and look forward to taking it on our Everest summit expedition next year.
