Just wondering if anyone could recommend a decent bag that won't break the bank for an Orizaba attempt in December. I have been looking at the Mountain Hardwear Lamina 0F synthetic bag, Marmot Never Summer 650 down bag (middle expensive), and EB Karakorum 0F Down (most expensive). Any recommendations would be awesome.
Also wondering if anyone could comment on a good layering system: I was thinking of a base dri-fit tshirt, cap3 long underwear top over that, Patagonia R1 hoody over, North Face Leonidas Soft shell, and then a North Face Micro Thunder 800 down light weight puffy to top it all off.
