NRS Ether HydroLock Dry Sack

Yes. The combination of the HydroLock zip-seal and the roll-down StormStrip top is designed to be 100% waterproof, even during full submersion.

The envelope shape is flatter than a traditional cylindrical dry bag, making it ideal for sliding into tight spaces like kayak hatches, backpack side pockets, or between other gear items.

The window is made from urethane, which is flexible and tough. While it is durable enough for standard outdoor activities, you should avoid dragging it over sharp rocks or abrasive surfaces to prevent scratching or punctures.

The StormStrip top acts as the final seal for the bag and doubles as a convenient grab handle. Once you have zipped the HydroLock seal, fold the top down and buckle it to create a secure, easy-to-carry handle.

Absolutely. The welded seams and zip-seal closure create an airtight environment that effectively keeps out fine particles like sand and dust, making it a great choice for beach trips or desert environments.

Consider what you are packing: the 2L to 5L sizes are best for small essentials like phones, wallets, or first aid kits, while the 15L to 35L options are better suited for clothing layers or sleeping bags. If you are unsure, remember that the envelope shape is quite compressible, so you can often size up without adding much bulk.
