Can anyone account for the difference in weight between the TrekLight double and the ENO double? TrekLight is listed at 19 oz, whereas the ENO is three ounces more at 22 oz. To the best of my knowledge, they are practically the same hammock with identical dimensions. I could be wrong.

I see that the ENO has a strap added to the stuff sack. I can't imagine that accounts for 3 oz. Does one come with heavier metal attachments for hanging?
