I recently had the #4 modification done on 2 HH Ultralight Backpakers and a HH Scout. The quality of the work is fantastic. I also had the slits sewn up for all three hammocks and the undercovers for the Ultralights and was very impressed with the attention to detail of the job. The gear organizers and peak bags were also high quality as well. The communication regarding all the details of the modifications and shipping was great. I was so impressed with the work that I am asking if they can modify my Ed Speer and Blackbird hammocks.
