FREAKIN AWESOME! This bag has room to spare. We are a combination department. We have Full Time / Volunteer level Firefighters.  We run Structure, EMS, & National Wildland Response.  This bag offers me room to carry both my structure gear, and my wildland gear. It makes it nice not having to carry two sets of bags. It has room left over that I can store personal items, extra clothes, and other items needed for a National response, while keeping my structre gear with me. I am impressed. This bag surpassed my expectations!
