I have a trash compactor bag, what is the candy cane closure you are talking about and where can I find one?

Zpacks has really good products and I did by a small dry sack from them, but it was not completely waterproof. A friend had a similar experience and filled his up with water and it leaked. My guess is the way they do their stitching.

Might ditch the crocs after all. I was bringing them for a luxury, and to let feet air out at the end of the day.
