tough. and i mean tough. i am 6'3" 204. never squeaked or creaked during the night. much easier to set up with these straps than the cordage on the Hennesy A-sym Hammock. just slap it around a tree branch and stick it into the other side of the clips... i know there is a balance to be maintained between lightweight and adaptability, but i would like to see more loops placed closer together at the distal end of the straps. i feel like it would help to more easily level out the hammock over a greater span.
