Brennan Kwrote a review of Patagonia Black Hole 2L Cube on August 18, 2017
Familiarity: I've put it through the wringer
I've used this since they came out primarily to keep my first aid and emergency supplies together in one place. This definitely does the job and holds a surprising amount of stuff. Sure it weighs more than other similar pouches may, but the black hole material has shown me time and time again that it is some pretty durable and bomber fabric. It is water resistant which helps in the winter time with snow sometimes getting in. It is easy to move it from pack to pack, or just to throw under a car seat for those car camping trips because it keeps everything together in one place.
In the small I keep:
Brooks -Range Ultralight Mini Guide Tarp
Full comprehensive first aid kit for 3
A couple packs of shot blocks
Various types of tape
There is still room to spare as well.
