Waterproof construction with a wrinkle-free roll-top closure ensure that sack contents are kept safe and dry. A continuous compression system encircles the sack to pack tighter and minimize seam strain, while a PurgeAir valve vents trapped air, helping the sack to compress further after being sealed. Fully welded seams provide unmatched strength and durability, compared to sewn-and-taped seams, and the 70-denier polyurethane-coated nylon is tough and versatile for reliable all-around waterproof protection. Unlike traditional, rounded stuff sacks, the SealLine Blocker Compression Dry Sack is shaped like a rectangle with flat sides that nestle closely together and pack 20 percent more efficiently, for space-saving organization. Available in a variety of sizes and colors for building out the perfect packing system for backpacking, camping, boating, expeditions, and travel. Manufacturer’s limited lifetime warranty. Made in the USA. ## Features - Equipped with our unique and waterproof PurgeAir valve that vents trapped air for easier compression and is more durable and waterproof than breathable fabric membranes - Dry bag features a flat-sided, rectangular shape that packs 20% more efficiently than rounded sacks for easy, space-saving organization in a backpack or duffel - Continuous Compression system encircles the sack to minimize seam strain, maximizing durability - Lightweight 70D polyurethane-coated nylon materials are tougher and more resilient than most other ultralight dry sacks - RF welded seams are more durable and waterproof than sewn-and-taped seams - Roll-top closure features a wrinkle-free stiffening strip to ensure a secure seal when closing the dry sack - Small 5 Liter size is ultralight at just 3.5 oz (100 g) and measures 6.4 x 3.5 x 11.8 in (16.5 x 9 x 30 cm) ## Technical Specifications | Specification | Value | |---------------|-------| | Item Package Dimensions L x W x H | 12.32 x 3.23 x 2.05 inches | | Package Weight | 0.15 Kilograms | | Item Dimensions LxWxH | 11.25 x 3.5 x 1.5 inches | | Item Weight | 0.27 Pounds | | Brand Name | SealLine | | Warranty Description | 3-Year Manufacturer Limited | | Model Name | Blocker Compression | | Color | Orange | | Material | Nylon | | Suggested Users | unisex-adult | | Number of Items | 1 | | Manufacturer | Cascade Designs Inc. | | Part Number | 09784 | | Model Year | 2018 | | Style | Blocker Compression Waterproof Stuff Sack | | Included Components | dry bag | | Size | 5-Liter | | Sport Type | Camping & Hiking, Outdoor Lifestyle | ## Images ![SealLine Blocker Compression Waterproof Stuff Sack - Image 1](https://m.media-amazon.com/images/I/71rx87VDD8L.jpg) ![SealLine Blocker Compression Waterproof Stuff Sack - Image 2](https://m.media-amazon.com/images/I/61zRMM3JF9L.jpg) ![SealLine Blocker Compression Waterproof Stuff Sack - Image 3](https://m.media-amazon.com/images/I/71V-vufws1L.jpg) ![SealLine Blocker Compression Waterproof Stuff Sack - Image 4](https://m.media-amazon.com/images/I/71Bmla5Z8dL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Convenient. *by T***T on Reviewed in the United States on July 20, 2023* I use this to carry a goose down sleeping bag. It is much easier and faster to put the bag in this dry bag than in the original and it compresses down farther so it takes less room. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Water/Air/Dust proof *by J***R on Reviewed in the United States on August 26, 2021* Keeps out water, dust and air. Easy to stuff and rectangle shape stops it from rolling which is an added bonus. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works Great! *by G***. on Reviewed in the United States on November 14, 2018* The media could not be loaded. Β I bought it for the wrap around straps and air purge. My son and I are going to Northern Tier so I needed something durable and able to keep things dry in very wet conditions. I loaded it up with my NT gear and put it in the shower for 15 minutes. Then I let it float for another 15 minutes. Everything inside was completely dry! I bought a 2nd one for my son. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/124609368-sealline-blocker-compression-waterproof-stuff-sack](https://www.desertcart.be/products/124609368-sealline-blocker-compression-waterproof-stuff-sack) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-06*
