Ursack has introduce a 14.2 oz. aluminum sleeve that fits inside an Ursack to protect the food from being crunched from bears. Has anyone used this piece in conjunction with their Ursack? If I understand correctly, The powers that be that test cannisters were concerned about food being crushed in there tests last year? If so would this piece of gear put them over the hump (Ursack)? Even with the 14oz added to the other 5-6 oz of an TKO would still be a great and lighter alternative to a hard sided cannisters. Any thoughts out there folks.
