very good sack so far! (Review by Rimmer)

Leading to an early spring expedition, I purchased a new pack this winter. I have relied on large Dollard store bought plastic large zip lock bag as a dry system for a few years now...the problem is and as been "compression and overall volume". Although my new pack is 75 liters and love it, the zip lock option was becoming bulky and burdensome. This review is premature since I have not tested the water resiliency but as far as my immediate needs it exceeds my expectations. The compression straps are sturdy and really do compress the content!. there is however an ( art/trick) on how to pack this sack...heavy non compressible items first, then the rest. The daisy chain is excessive but will become very useful since I use a Hennesy hammock and don't have a lot of room to keep things dry in the tent. It will allow me to hang my dry bag just under the opening of my tent but if the water repellent is true I don't even need to be worried about that . I have the 15 Liter and was able to compress all of my dry stuff plus a few pairs of socks...happy feet! AND it fit nice and snug within my pack which is why I like this product so much. More to come when I test the Canadian harsh spring in Algonquin

Great compression sack (Review by out there)

Ok, so its hard to get excited about a compression sack, right? This one is perfect. I was on a multi day kayak trip and needed UL and bomber waterproof. It is totally waterproof, super lightweight, and the air purge thru the yellow patch means that after you compress it down to a little ball, you can sit on it and make it flat and even more compressed. Its so simple and effective.
