Agreed with above, just get a quilt. I own a few for my hammocks (which I also own a few) there are plenty of shots in the forum under my user name incase you want to search but my go to is now hammock gear. I have a 0 and 30* setup. Just remember you need something under you in a hammock too. wind will pull the heat our your bottom and give you CBS (cold butt syndrome). I also have some JRB quilts and a next but the hammockgear is still my fav. Some of the hammock setups this winter And some size comparisons, this is my hammock and large tarp (with doors for sealing yourself in if needed). Hammock is a warbonnet blackbird XLC, tarp is a warbonnet superfly. I use whoopie slings with a toggle/ marlin spike hitch setup. Hammock compressed Fly compressed My 0* insulation (actually overstuffed so its closer to -5 or so but still) FYI this is WAY higher than your price range. The JRB stuff can be had on sale thruought the year, so keep an eye out to save a few bucks, but it still cost a pretty penny. Check out "the ultimate hang" by Derek something or other for some great advise.
