As of July 31, 2014 the Ursack S29 All­White has been placed on the Inter­a­gency Griz­zly Bear Com­mit­tee (IGBC) list for cer­ti­fied bear resis­tant con­tain­ers. It is impor­tant to note that no pre­vi­ous mod­els of Ursacks have been added to the list.

In 2012, Yosemite and SEKI (Sequoia/Kings Canyon Nation­al Park) turned over the Ursack test­ing to the IGBC. Now that the Ursack has cleared this hur­dle with the IGBC, it is pos­si­ble — and although I am hes­i­tant to say it after so many years of review, maybe even like­ly — that the Nation­al Park Ser­vice (NPS) will approve of their use.

In light of this new approval, the NPS has not yet for­mal­ly admin­is­tered an approval of the Ursack S29 All­White. Since the review was done by the IGBC this will most like­ly have to be approved but he NPS before per­mit­ting hik­ers to car­ry the Ursack instead of a hard-sided can­is­ter. I WOULDN’T push your luck car­ry­ing the Ursack over a hard-sided can­is­ter until the dust has set­tled and details have been worked out, although tech­ni­cal­ly if you car­ry the cur­rent IGBC approval list you MAY be able to talk a ranger out of the citation.
