I just used my new 50 degree trail winder underquilt this past weekend. At 44 degrees it was kinda cold. At 55 degrees it was still a bit cool but quite doable. I am a cold sleeper and don't plan on using it below 60 degrees anyways. I love how easy it is to set up once you have fit it to your hammock. Its just loop it on one end and clip it on the other, just like my wookie. Big thumbs up.
