Waterproof, lightweight dry sack with space-saving compression.
Our most versatile, feature-laden packing system sack, the Blocker Compression Dry Sack saves space on paddling and trail adventures, while the waterproof valve rapidly vents trapped air to ease compression—all this with fully waterproof construction ensures essential contents are protected, condensed and organized.
Details
- Versatile materials: Lightweight 70D polyurethane-coated nylon materials are a tougher, more resilient cousin to the ultralight BlockerLite materials. More durable and versatile, these materials are great for all-around use with confident waterproof protection.
- Smarter compression: Unlike conventional systems that pull against seams, our Continuous Compression system encircles the sack to minimize seam strain, maximizing durability for dependable protection.
- PurgeAir™-equipped: Our unique and waterproof PurgeAir valve vents trapped air, helping the sack compress further after being sealed, and is both more durable and more reliably waterproof than waterproof/breathable fabric membranes.
- Waterproof closure: Roll-top closure features a wrinkle-free stiffening strip to ensure a secure seal when closing the dry sack.
- Durable construction: Fully welded seams result in stronger and more durably protective construction compared to sewn-and-taped seams.
- Efficient-Packing: PackTight™ packing system sacks feature flat-sided, rectangular shapes that nestle closely together, packing 20% more efficiently than rounded sacks for easy, space-saving organization.

A Perfect 5-Star Refill Solution!
Color: 2 Black,1 Cyan,1 Magenta,1 Yellow
As a heavy user of my Epson EcoTank printer, I am always on the hunt for reliable, high-quality, and cost-effective refill ink, and the QIOCKTO 522 set is exactly that—a phenomenal find!
Effortless & Mess-Free Refilling: The design of these bottles is truly genius. They feature the same key-lock nozzle system as the OEM bottles, meaning they only fit into the correct color tank, and the refill process is completely automatic and totally mess-free. I didn't spill a single drop, which is a huge win for EcoTank owners.
Exceptional Print Quality: After refilling, the print results are indistinguishable from the original Epson ink. I've printed everything from detailed photos to plain text documents, and the colors are vibrant, the blacks are deep, and there is no smearing or clogging. My printer recognized the ink perfectly and continued operating without any errors.
Incredible Value: This 4-pack offers a massive volume of ink for a fraction of the cost of the brand-name refills. For the quality and the quantity you receive, this is hands-down the best value on the market for keeping your EcoTank running.
If you own a compatible EcoTank printer and want to save money without sacrificing quality or ease of use, these QIOCKTO 522 ink bottles are a must-buy!

Easy to use Ink Refill for Epson printers
Color: 2 Black,1 Cyan,1 Magenta,1 Yellow, Color: 2 Black,1 Cyan,1 Magenta,1 Yellow
This was a fantastic ink refill for my Epson 522 printer. I had been simply purchasing new cartridges in the past, but I decided to simply try to refill it the current ones that I was using. This was easy to use and surprisingly mess free. It didn't change the compatibility once I refilled the cartridge, which was a worry. The cost was very reasonable considering the expense of buying new cartridges. The quality was high when I started to print, and I was very impressed that there was no smearing or degradation in the ink or the readability. This worked very well, and I am extremely happy with the product. Clean up was trivial. I was amazed that there was no leaking either. Would definitely buy again.
