The MyFAK Large is a great upgrade for probably-too-prepared field medics like me who like to carry a ton of stuff "just in case." The bag offers great organization with good-sized pockets to store a variety of things, even some bulkier stuff that tuck nicely into the larger mesh panels. Having all the compartments be mesh is also great to visually scan everything a find what you need in an emergency. The quality seems really good and I assume it would handle some rough usage, although I keep mine in a waterproof vinyl bag for wilderness excursions that may encounter rivers or downpours. If My Medic could produce a waterproof (or at least highly water-resistant) version of this bag... that would be incredible.
