m block wrote a review of DAKINE Blade Pack - 1800cu in on March 3, 2008
I own several packs,three of them being Dakine. This bag holds all my backcountry gear, shovel, probe,and first aid gear. Even when the day warms up it can hold all my layers. I use the bladder from my other Dakine pack and have no issues with freezing tube or valve.
