Ive got a 1.9 coated ripstop hammock- double stitched end channel style- comes with 20' of 1 inch polyester webbing. This hammock measures (flat) 4' 10" by 9' 4". It should support 250 lbs as it is- the channel is reinforced at the ends by grosgrain ribbon. the webbing Im including is not attached to the hammock and has no rings or buckles with it. you will need to supply those yourself, and i would consider the JrB "tri-glides".
I have too many hammocks, and this one is pretty large (to big for me )
