aLOKSAK bags are resealable element-proof storage bags featuring a hermetic seal. That means absolutely no water, air, dust or humidity permeates the closure. The transparent bags are flexible, puncture resistant and designed for various applications and environments.\nLokSak says:\nThe aLOKSAK is an element-proof storage bag that prevents leakage and preserves items against damage from water, air, dust and humidity. These bags are made of a durable polyethylene blended film and are 100% water/air tight. They are considered disposable though, unlike other 100% water/air tight bags, they can be opened and resealed numerous times.\nIdeal for: TSA size for travels. Unlike other commercial zip closures that leak, the aLOKSAK resealable closure forms a hermetic seal which does not allow any leakage. No more damage from toiletries leaking during your flight. \nContains 2 bags.\n\nOur Verdict\nThere would seem to be nothing much to say about a re-sealable bag – but there is! I’ve been keeping my phone in one for the past month – constantly taking it in and out of pockets and bags, opening and closing it about once a day to charge the phone. Result? – The bag still has a watertight/airtight seal.\nSo, a bag is not just a bag. There’s no comparison between one of these aLokSaks and the re-sealable bags you buy for the freezer – the seal is much more effective and durable for a start, and the bag itself is made from a higher grade of material, so its a lot tougher. The seal is easy to open as the back is offset from the front (you’ll know what I mean when you see one).\nFinally on product life; it may be that aLokSaks don’t last as long as more bespoke products, but when they wear out its no hardship to get another one, and I have no doubt that they will last the length of your trip however far and for however long you roam.\n- Reviewed by Ultralight Outdoor Gear\n\nFeatures\n\nCertified waterproof to 200 feet/ 60 meters\n100% protection from water, sand, humidity, and snow\nMade in the USA\nReusable and recyclable\nFDA and NSA approved medical grade materials for food and biohazard storage\n\n\nSpecifications\n\nWeight per bag: 14g\nOuter dimensions: Outer dimensions:8.75\
