A good E&E bag is essential, and when you do find a truly good one, it can be wonderful. The Tac Ruc E&E from MilitaryLuggage.com is a truly good bag. So much so that I'm considering making it my SAR bag since the things needed for an emergency bug out are much the same for an emergency SAR call-out.
At 12x6x20, it is a roomy bag and the abundance of webbing makes it easy to cusomize.
The interior is indeed roomy. The bag overall appears to be rugged, well built, and ready for some hard use. It is also avialable in coyote brown.
If you decide that it's not for you, well, the fine folks at MilitaryLuggage.com have a new return policy you need to know about:
Basically we are so confident a customer will be pleased with their products, if they are not we will take it back within 30 days if it’s new, unused with original tags. BUT here’s the real part of that guarantee. The customer does not have to pay to ship it back. We send a prepaid shipping label and they ship it back at no expense. We will do this anywhere in the US (including Alaska & Hawaii). With APO customers since we cannot send a prepaid shipping label, all they have to do is send us a postal receipt showing how much it cost to ship back and we will refund them that. It’s a true no risk guarantee.
Full details are here. Selection, price, and real customer service: you can't ask for more.
