Familiarity: I've put it through the wringer
These dry sacks really are phenomenal. I use them as stuff sacks for my sleeping bag. The taped seems and waterproof fabric give me a little extra security on ski mountaineering trips while the taped seems and waterproof fabric allow me to compress the contents and seal it up as small as most compression sacs without all the extraneous straps and fabric of a traditional compression sack. It is definitely a piece that is a little fragile as most ultralight gear is but if used mostly within you pack it lasts and will remain unscathed!
