Made a believer out of me.
I am usually wary about compression bags because a lot of the time they are just added weight for little compression. I have used the eVac dry bags for clothes and my sleeping bag and they worked pretty well. I decided to try the compression version after all the positive reviews and was truly impressed. It got my long Marmot Sawtooth down to a little bigger than a basketball. It is really easy to use and I know it will keep the down nice and dry.
