I realize that this is a bit off the backpacking orientation of this site, but I hope you can make some suggestions on a good summer weight, light sleeping bag.

I am planning a hostel to hostel week long hike in Spain next spring, so am looking for a sleeping bag of about 45 degrees, hopefully light and small. I am considering the REI Travel Down sleeping bag, $139 and about 28 oounces.

I don't want to go the expense of the Western Mountaineering bags in case the bag picks up bedbugs on the trip and has to be thrown out before I come home.

So-

Any comments about the REI travel down bag?

Any suggestions for a good 40-45 degree down bag which is light and won't break the bank??

Yeah- I know- light, warm, cheap- pick two---

Thank you!!
