The Exped suspension is their take on ladder straps, looks like it shouldn't work but it does and I'm happy to trust it.
As promised, here's a shot of the Exped Travel Hammock Plus (not the Travel Lite Plus) in its stuff sack along with a 750ml water bottle for comparison. The other bag is the homemade 3.3m/11ft hammock with its suspension.
The Exped will compress further, to about the length of the word "Exped" on the side of the bag, the Lite version starts out 3cm shorter to begin with so will compress that little bit more. The homemade one will compress to about half the shown size - that's just a bag I happened to have lying around that it would fit into. The Exped weighs 420g, the homemade one 490g. (The Travel Hammock Lite is 260x120cm in size whereas the Travel Hammock is 250x147, the homemade one is 330x150)
Edit: Without the suspension the homemade one will fit into a standard Alpkit Stem Cell so I'd say that the Exped would compress to that as well /edit.
Hammocks are a bit of a learning curve, for me at least, and figuring out what is best (for you) isn't easy. There's no simple formula of: You are X tall so need a hammock X+Y% long, X/n wide, with foot end higher than head end by so many cm. Seems to be a bit like bikes: some just work for you while others won't fit no matter what the geometry figures say. It gets to the point it's all personal preference! I could use the Exped for sleeping but I think I need to dial it in very precisely for it to work for me. The extra length of the homemade hammock gives me some leeway in that regard.
Really need to get some shots of me in both to give an idea of relative sizes, etc.
