I bought this only a month ago, and have had two tow night hangs since. I went for the Frontline rather than the traveller hammock, as I'd ready that the waterproofing on the traveller had caused condensation problems for some people. I don't intend to use it as a bivi on the deck so the waterproofing I didn't need the waterproofing anyway.

I emailed them and asked them to swap out the sleeping bag liner for two Karabiners, and they added £2.
The bag is ok, a basic canvass style, but it does the job. I managed to get two days worth of clothing, sleeping bag, 3/4 thermarest, blanket, tarp and Hammock in the main compartment. Washkit, knive, Spare cord etc went in the side pockets.
In all a great buy, and the Hammock is brilliant. The tarp did tear on the second use, but an email to DD sorted it, and they sent me out a replacement that I got the very next day.
In all, you can't go wrong with DD, and the customer service is brilliant.
