I've owned & enjoyed my Mosquito Jungle hammock for many years now; taking it with me on numerous bike trips and hike trips. I've always slept on a insulating pad in my hammock when out doors. But I noticed during a couple of indoor hangs, without the pad that the hammock was much more comfortable. What I needed was an underquilt. This year I was finally able to justify the purchase of an UQ (a bonus from work made it possible). I bought an Enlightened Equipment Prospect 76", 30 degree synthetic UQ. Over the last week or two we've had some hot days in the Pacific NW so I set up my system outside and have enjoyed some comfortable nights. I am really pleased with my new purchase.
