Chemical Defense Gas Mask Pouch
My original intention was to look for those generic sling pouches (aka Chalk Pouch) with cushion inside, to use for lenses or bottles, but most of them are intended for hooking using karabina to belt loop or for slipping across belt. Most of them are not able to be mounted top-down, which was what I required. Furthermore, they are mainly drawstrings and though quick access, but contents are not completely sealed and not to mention water-resistant. Then, I came across a Lens Pouch by Tatanka which are the right type of mounting using buttons instead of velcro. I passed on that since it is not versatile and expensive ($25-28), though water-resistant guaranteed. There are other pouches that seem like a fusion of the Tatanka lens pouch and chalk pouch, they are slightly cheaper (~$18) but a tad too small. Hence, I decided to settle for the D&G (not to be confused with the designer brand) CD Gas Mask Pouch which is reasonably-priced for the versatility and size, I just hope that it is water-resistant, but nonetheless, I will always have ziploc bags ready.
