I like this for the price and for my purpose.
Last year I went hammock camping in August, expecting lows at night to be in the 50s. Instead we got driving rain, high winds and 40s.
keeping warm in the wind in a hammock can be challenging on a good night, I had the gear to manage what we expected, but not what we had!
So I took a simple fleece blanket I had with me and jury-rigged an under-quilt with it using rope and some shock cord and it served to get me through the trip with some middle of the night adjusting when a gap opened up under me and I got cold.
An under-quilt is essentially a barrier to keep the wind from drawing heat off the bottom of a hammock. Since insulation is compacted under your weight, and hammocks are thin, the bottom is where you lose most of your heat.
I bought this blanket and snapped 5 grommets along both ends and 2 grommets each side. Then I threaded some paracord through the grommets with a barrel lock for adjusting. Total cost was less than $20 and it fits well, packs small and will be used if we see low temps licke that again.
