Anyone tried them? The 14L grizzly sack by Adotec is certified bear resistant (like Ursack), weighs 199 grams. It's basically a thick dyneema rolltop bag. Ursack weighs in at 249 grams.
Of course it costs more than an Ursack, but not that much. I've gone in the direction of bear resistant bags over BV450's, I think overall it can be lighter.
Adotec has larger bags, but only the 14L is certified at this time. Rangers have def stopped me in the BW and enquired about my bear-resistant systems.
Oh, by the way, make sure not to stumble and fall into the STAUBER if you get up at night to take a leak.
Now about those bear bags - anyone tried one?
Adotec is a tiny company run by a Canadian couple. I love supporting such a venture.
