The SOTAR Gear Bags are made to hold your gear water tight and safe. We use 22oz PVC on the body and 40oz PVC on the wrap up bottom. No other bag is tougher. All Gear bags come with ergonomic shoulder straps for ease of carrying whether you are setting up camp or making a long portage. With a top carry loop and numerous D-rings these bags are easy to load and secure in your boat. Would you believe this is where SOTAR began years ago? Glenn and Randy designed and produced a line of waterproof gear bags in the early 80's in a shop of less than 600' ft This endeavor morphed into SOTAR and our line of inflatable's we have today.
