User Review: Granite Gear AirVent DryBloc Solid Pack
Price Paid: $22
This thing rocks. The picture doesn't show it, but this is a roll top dry sack as well as a compression sack similar to the Sea to Summit eVent compression drysack, but even better as it is ultra light weight.
This is the perfect compression sack for down sleeping bags or other gear you need to keep dry without adding too much weight.
