    Default Sleep system for Annapurna & Machu Picchu


    I'm planning Machu Picchu & Annapurna gear list. For both I'm being recommended a -10C sleep system, so I would like to invest once to cover both these treks.
    I currently have a Marmot Phase 30, so far from fitting the temperature. I see 2 options :
    - I buy a sleeping bag/quilt that covers -10 : simple solution, but it limits the use of it to these 2 treks only (or at least this type of treks).
    - I buy a quilt to use with my Phase 30 (current idea being EE Revelation 20 as outer layer) : the versatility of the layering system would theoretically cover all types of trek I could do in the future, however I'm reading on different forums very opposite opinions - some love the layering system, some state that the compression of the outer layer on the inner results in loss of insulation and therefore doesn't work/too risky.
    I'm not an expert, specially for these mountain treks. Do you have experience in using a layering system for those, or met with people using it? Any recommendation?

    Late reply but still... It all depends when you are trekking in the Annapurna region and if you plan to get high. No, I mean walk to high altitude, as in crossing Thorung La or going to Annapurna Base camp. If you do these in the November to February period - you must have a good down sleeping bag. However, a moderate sleeping bag, with a blanket or two will be ok. Lodges in the Annapurna area provide extra blankets. I do not think you will suffer of cold in these conditions (it will be like -5 degrees inside the room at 4800 m altitude in High Camp on the Annapurna Circuit or at ABC) but it will be less comfortable with all that weight on top of you. But you will not die. I think... Still, a good down sleeping bag is difficult to beat. You can purchase one in KTM for 120-150 USD, a really good one. Or maybe just hire one for 2 dollars a day for the trek.
