Every seam has ripped — repaired with aqua seal and that has failed.
Lightweight but not durable! Every seam has ripped and I can’t repair.

Works but will tear
Worked great initially to compress everything and keep it dry. But with just some clothes in the pack, one seam popped on the first use.

Durable, Compressible and water Resistant
Nice product when space is limited and protection for clothing is necessary in the back country.

Good product. No issues. BUT.. could be better.
Great compression dry sacks. No real issues. We use these for our sleeping bags. One thing that could make it better was if 2 of the straps could have a buckle incorporated in with the strap adjusters. This would be very useful in the chance the straps get twisted(as the do often when nothing is in the bag.).. you could then unclip 2 of the buckles and quickly untangle the straps and then buckle it back with ease.

Works well for outdoor gear in any weather.
I use these when packing gear in to a several day trip in the back country. They compress great and are very light weight.

great compression sacks
I have used my compression sacks backpacking on the rainy lost coast, CA and have held up great, excellent for compressing and kept my gear dry! Stoked on my purchase!

5L Fits Hyperion 20 regular perfectly!
Bought this for a waterproof solution to packing my Hyperion 20 regular. 5L Blockerlite Compression fits the bag like a glove. Compresses down to an extremely small size and I have no doubt the waterproofing will hold up. Photo next to my hat for size reference when compressed.

Great for my sleeping bag
I have the 20L version and use it for my heavier down sleeping bag. It compresses nicely and the AirPurge is a great feature to get it down as small as possible. It's lighter than what I used before so that helps keep weight down in my pack, too. Doesn't need to be super durable since I'm just moving it from my bag to my tent and it's not getting beat up outside.
