A combination of light weight under and overquilts and all packaged with a decent weight. I, at first avoided the Grand Trunk Evolution hammock because it appeared heavy at 4.2 lbs. Once I realized that adding all my gear together came out heavier, I went with the Grand Trunk. So much easier than worrying about hanging underquilts...

If you are camping in a hammock in the winter, this thing is for you. It’s incredibly comfortable and warm. I used it for two nights in sub 30 degree weather. I stayed nice and toasty.

Say goodbye to that cold under draft and say hello to absolute comfort...I was worried that it wouldn’t keep the heat in and I was wonderfully wrong. I can’t wait to keep putting it to the test this summer because so far it has fulfilled everything I could of hoped for. This is truly worth every penny.
