I have 4 cabelas auto inflates, they are comfortable especially for someone that likes to wear theres all the time. Do not store them in the dry compartments when traveling. I have worn my in rain storms and did not inflate but nothig worse than going on a fishing trip, opening the dry compartment on the boat, only to find them all inflates. $25 or more on each recharge kit later, my vests were ready to go. Always put in cab of behicle when driving.
