I purchased a Hammock Gear Burrow 20 in January of 2016, so I have had it for 2 years of hiking on multiple long trails. My girlfriend also has a Burrow 20 that she has used for 2 years. We also both have the 40 degree (+1 oz overstuff) version of this quilt that we bought in 2014. We are both under 5'7" tall with slender builds and we went with the short version. We both opted for the sewn in foot box. Weights on each quilt is 16.5 oz and 16.6 oz. Both the inner and outer shell fabric is made of Argon 67. The price on each bag was $249 + $10 s&h. I am a normal temperature sleeper and MtnGoat sleeps cold.
2016 Colorado Trail (mid-July through early August):
Night time temperatures were between 25 and 40 degrees depending on the elevation. In general the nights were windy and cold. We slept in a Fly Creek UL 2, so we had the added warmth of a tent. There was a lot of wind, fog and a few nights of heavy frost. In these conditions we were really happy with the Burrow 20. We never slept cold and the bag did an excellent job of maintaining loft through damp conditions.
2017 Long Trail (mid-September through early October):
Night time temperatures were between 30 and 55 degrees. We carried a Fly Creek UL 2, but never set it up...we slept in the shelters every night. The nights were really humid and the air stayed damp. The bags kept their loft and we were never cold even in the drafty shelters.
We are planning to use these bags on the JMT in 2018.
I will stress here that MtnGoat is a pretty cold sleeper and she has never been cold in this quilt. We were sleeping in Patagonia base layers (cap 2 bottom and cap 4 hoodie top). We have both been extremely happy with these quilts and I feel the price is more than fair. The quality of construction is excellent and all 4 of our Burrows are holding up great. These quilts are literally one of our favorite pieces of gear.
I just thought I would do a quick review of this quilt because there are hardly any reviews or discussions about it.
