We reviewed the SHIELDSAK by LOKSAK a month or so ago. We picked up another product from LOKSAK, this is call the OPSAK...that s a lot of SAKs. This SAK is all about keeping things sealed in or sealed out. I've been using it lately to seal out the water while listening to pod casts in the shower.....
The OPSAK is a heavy duty -for lack of a better term- ziplock type bag, except the OPSAK is very heavy duty. You can see above I have been using the OPSAK to store my SHIELDSAK with its electronic contents.
They make several sizes. The cool thing about the smaller bags are how perfect they will fit our 2 mobile phones. We have an old school Apple and a Samsung Galaxy S4. Each one will fit perfectly into its own small bag. The other feature I like is the phone screen will still function when you are using it sealed inside the bag.
