Just got them so all I’ve done is stuff one to the gills with clothes but as always, craftsmanship is outstanding , as is attention to detail. This new fabric looks & feels tougher than regular Dyneema. A tiny bit heavier but I don’t count grams so it doesn’t bother me to trade some capability for a tiny weight penalty. Photo is Med long sack W / bulky 650 fill down vest, two merino balaclavas & room for 2 folds to make water tight. ( I know most people say you need 3 folds but I’ve not had problems with just 2 ).
