Hmmm...if I'm not mistaken the Ursack is 7.3 oz. and holds the equal of a big canister.
wbtravis... I have always wondered about the Ursack.
Are there any USFS Districts or NPS authorities that recognized it as "kosher."
Also this may be silly, but how do they stand up to Marmots? In the last 6 years I've spent in the High Sierra I've been given more trouble from Marmots than bear (I've never even seen a bear in Whitney Portal or the Backcountry [including the JMT]).
