Granite GearRunning

サイズは手頃で、使いやすい。軽量でコンパクトなので、ザックの中がパッキングしやすいと思います。是非、お試しあれ。

At first glance this looks like any other compression sack, and you start to wonder why you bought it in the first place. But then you stuff it full of gear, compress it down to nothing, realize that it fits nicely in your pack, and its waterproof; it's at this point that you come to find out that you actually got your money's worth.As far as compress-ability is concerned, I use this for my Hammock Gear top quilt and I can reduce the size of my bag by half when compared to the sack that it came with.Waterproofing seems excellent as well, I haven't field tested it yet (thankfully). But I did fill my sink full of water, and fully submerged my bag several times, then left it floating in the sink for almost 30 minutes. I wasn't planning on leaving it in the water that long, but I forgot it was in the sink after a few minutes. Much to my surprise my quilt was 100% dry!Great product, and does exactly what it's supposed to do.

These are the greatest for backpacking. Cheaper than the similar and more expensive ones I bought at a local camping store. The strings get tangled sometimes but no biggie. Kept my clothes dry on a 2 week trek in New Mexico last summer.-R

It’s lightweight and it compacts well for storage when you aren’t using it. Hasn’t broken on me yet.

Lightweight and strong. Very happy with my purchase.
