OK folks, Going to be doing some work and looking for a day bag - something to take into recovery zones for 10-12 hours at a time. Needs to hold the typical gear associated with mucking out houses, clearing debris and being pretty much self-sufficient for the day. Obviously, looking for durability as its going to get trashed and I dont want to replace it every time I go out. External water bottle pouch, someplace to tie down a helmet and gloves and some MOLLE would be perfect. Not looking to drop a ton of cash on something that's going to be mission specific (no way that bag gets used for anything else after spending time near contaminated water and the debris associated with it). Thoughts?
