Another go-to when traveling to any destination is the Jungle Bag from Snugpak. Almost fits in your pocket yet its a solid sleeping bag with a 55 degree rating, insect netting and did I mention that it compresses down and fits in the palm of your hand?
You can accessorize the bag with an additional insulation layer from Sea to Summit which can add an additional 10 to 15 degrees of rating to the bag (highly recommended).
A great deal with a low cost - $79 direct and on Amazon.
We have bags with more loft (and a higher price tag) but the Jungle Bag gets the most use.
