The fabric is actually 1.0 oz/sy and I am at 200# and I would go double layer.
BTW, I have used this fabric before to make a hammock over cover for my Blackbird and for a hammock sock. It's light weight and extreme breathability are perfect for those applications too.
I have enough woodland camo 1.1 that is also super wide for one layer and I'm going to add one layer of the ACU camo to make a double layer reversible hammock depending on the foliage and season of the year.
