I recently shopped for a medium size x-pac pouch, and I believe that the Rennenn X-Pac Pouch is the winner among similar rivals from Able Carry and Flowfold.
First, why x-pac? X-pac is a highly water resistant material.

Second, why the Rennen X-Pac Pouch? I compared the Rennen to similar x-pac offerings from Able Carry and Flowfold. The Rennen is superior in regard to size, materials, and value. The Able Carry Stash Pouch is a quality item, but it is too small for my needs and appears overpriced (for its size) at $23-$25 USD. I was really underwhelmed by the small size of the Able Carry Stash Pouch. The Able Carry Stash Pouch also does not possess a water resistant zipper like the Rennen. The Flowfold pouches are quality items and come in larger and better sizes than the Able Carry Stash Pouch, but these pouches also lack water resistant zippers.
