James V.wrote a review of Arc'teryx Lunara 10 Bag - 610cu in on May 29, 2014
Familiarity: I've used it once or twice and have initial impressions
This bag has a very simple design - a large internal pocket with an elastic band and an outer zip pocket. The material is rugged, stiff and loud, a bit more fabric-y and supple than a dry bag, but not much. That said, it's not designed for a laptop and office supplies, (and for that reason I almost sent it back when I first received it.)
I used it recently however as my medical kit for a recent trip to Haiti, where I served as the team physician. It was really perfect for this purpose. I squeezed my customized Adventure Medical Kits, size Guide I in the main compartment, and my stethoscope in the outer zip pocket. Through dust, rain, orphans, and rides in the bed of a modified 4X4 on dirt roads, my equipment and supplies were clean and protected. On returning home, I wiped the dust and grime off with a Clorox wipe, and it's looking good as new. The bag will now continue to function as my first aid grab-bag on Boy Scout trips and family outings.
My complaint would be to do away with or allow for adjustment of the 1 inch elastic strap inside the bag. As featured, it allows for stabilization only of perhaps a hard-back Tom Clancy novel. The strap does not secure anything thinner, making it worthless I think.
