I always go for snaps, for the same reason and that they create a weakest link that will give before the fabric in case of mishap. I've often uncinched my foot box to vent my feet and wouldn't be without the option, so no sewn footbox for me. The fabric is dutch's 0.67 for the tops, orange one side black the other ( I've made the inner / outer the same so it can be flipped depending on which side is grubbier / how stealthy I want to be etc) and 0.75Oz 7d Robic with the breathable/almost waterproof coating (same spec as pertex endurance but less than half the weight). That 10d may well be the same stuff as Dutch's $10/m 0.67oz. Shell is finished, we'll see how long uk hammocks takes to deliver the 350g of 850 polish down. I've sewn the baffles 2" for the bottom 1m and 1.75" for the top as I inevitably end up sleeping in my hypertherm smock and this quilt is meant to be as light as I can make it within its design.
