I purchased this bag for use in backcountry rescue scenarios. Plenty of room for all of the medical equipment plus extra room for layers and other hiking/camping essentials. Bomber construction, super fast shipping, it came with a red cross velcro patch (not listed on item's description) and also a free duffel bag! The free duffel was a total surprise and I'm now using it as a gym bag. Totally satisfied with this purchase. I will DEFINITELY be ordering through MLC again!
