Have had a Greylock 3 for a couple years now and couldn’t be happier with my choice. Always warm enough, deflects rain droplets that ricochet off the ground during storms, stays snug in position all night. Hammock camping friends of mine who went with cheaper options always say they are jealous of the Jacks R Better. I can safely say if you’re looking for a nice workhorse of an under quilt for your typical hammock setup, this one will not disappoint.
