I started out my so far short career in hammocking with the Expedition. Alas, it was just too short to be comfortable for me (6ft 2in, 230lbs). I should have spent the extra to begin with, but finally sprung for the Explorer Deluxe with Side Zip.
I spent 4 nights (5 days out on the road on the m/c, from Vancouver, to Kettle Falls, WA to Heron, MT, to Coulee City WA, and back to Vancouver) in the hammock. Wow, I was so comfortable. While the bottom entry is a neat idea, I find I prefer the side zip. The extra length and width of the Explorer was also nice. I got a nice flat lie all the time, and slept very soundly. I did not miss my tent one bit.
Its also amazing what a conversation starter it is. I would roll into a campground in the afternoon, unload, set up the hammock, and soon enough anyone who passed by would ask about how I managed to get so much on a bike, and gee, is that a hammock?
