When I originally bought my HH Exped Asym I didn't realize the correlation of hammock size to occupants comfort. The stats said limit was 250# which happened to be what I weighed and at 5'9" I didn't figure my height to be an issue. After testing it a few times and finding this site I realize that I would have been better served with either the HH Expl Deluxe or the HH DJ XL but I am cheap & at the time, knowing virtually nothing about hammocks, wouldn't have sprung for the xtra $$ anyway. In time I have figured out a good lay & am currently happy with what I have although I am now looking for a wider & possibly longer hammock but that's another story. I'm looking at the Eno dbl or Traveler 1.7 dbl layer and leaning towards the Traveler.
Due to cost I decided on the HHSS for insulation instead of an UC, did I mention I was cheap . After testing, lowest being 27 deg, I can say I am quite comfortable with the SS & an OQ but I did find myself waking a couple times a night to cold spots after I shifted from back to side or reversing lay. I am a wide body so when I shifted part of me ended up off the pad. Fortunately I had gotten the HQ2Q mod #3 (which I highly recommend if you have the classic) so reaching out & adjusting the pad was quick & easy. Unfortunately not being fully awake and somewhat irritated at having my sleep interrupted for no apparent life threatening circumstance I put my thumb through the fragile pad, on both sides I might add. While not a big deal I couldn't do this too often without having an inventory of pads so I began looking at remedies. After some discussion with HH I purchased the pad for the Expl. It is aprox' 3-4" wider and only about $5. more than the pad specified for the Exped. After a couple of nights down to the low 30's I can say problem resolved, never woke up due to cold spots even though I did shift several times a night. Amazing what a few inches will do. As a side note; when the temps start heading below 50 the recommended space blanket over the open cell pad of the SS is necessary. I have read the complaints about the rustling of the SB but if you tuck the xtra back under the pad once you get in it becomes a non-issue.
