## Overview

The SealLine Blocker Compression Waterproof Stuff Sack is a 5-liter ultralight dry bag designed for outdoor enthusiasts. Featuring a unique waterproof PurgeAir valve for easy compression, it maximizes packing efficiency by 20% with its flat-sided design.

Weighing only 3.5 oz, it’s the perfect companion for camping and hiking adventures.

## Description

The SealLine Blocker Compression Dry Sack is a fully waterproof roll-top compression stuff sack for organizing, condensing, and packing contents in backpacks and duffels for trail and paddling adventures. 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.

### ⭐⭐⭐⭐⭐ 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.

     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.
