Quito weather isn't that bad. The 9200+ elevation is reporting 68F, thunderstorms and humidity 49%. The jungle area, considerably lower in alitude is gonna be warmer and a lot more humid. The equipment list options for either a bivvy sack or sleeping bag. The bivvy sack promised - didn't make it - darn. The ones at the store are $200+. Even worse my wonderful North Face down bag, suitable for Mount Everest Expeditions, will most likely soak up moisture and stay wet the whole time.
Online I can see the Kelty Light Year XP and the Mountain Hardwear Lamina. Does anyone out there have any experience with either?
Kelty Light Year XP
"The Light Year XP 40° is a summer-weight synthetic bag with a hip-length zipper and zippered foot vent that is perfect for light and fast adventures in unpredictable conditions."

Mountain Hardwear Lamina
"The Lamina™ 0 is an excellent choice for damp, winter conditions. Welded layer construction maintains loft in the bag through repeated washings and compression cycles. This comfortable, roomy, mummy cut bag is insulated with ThermicMicro™ fill. Face gasket and Ergo Draft Co"

They are both light weight and synthetic - key for this adventure. They both compress into really small stuff bags another nice feature. Have any of you used either bag? I am leaning to the Kelty because I burn up with the North Face Inferno and the Kelty is the warmest. Ideas - anyone?
