Emergency Kit Logo needed

CEK-- this one is specifically for College Emergency Kits

I create individualized emergency earthquake kits for colleges. I am a startup company. Eventually, the "C" might be Corporate or Community or Car (you get the drift). I want something that is simple that I can put on the bottom of a backpack or small duffle and also on my brochure and website. The backpack and kit will also have the college or university logo in the forefront.
I am a mom of four- your average, disaster preparedness freak... who had an idea that people seem to have grabbed onto...

While the users of this product are college students-- the buyers will be their parents. It is a serious emergency kit but I don't want something too stuffy or "governmenty" (is that a word). The buyers could also be university officials who want to be re-assured that this business is legit.

Originally I was thinking of a monogram with the E in the middle-- or something with the c surrounding the e and k.
I am hoping for something simple and classic but also cool that doesn't just feel "standard issue". I am also hoping that eventually I can use the logo as the business branches out.
Again, nothing cartoony or difficult to produce.
One color if possible because these are going to be mass produced potentially embossed or even ironed on....
I hope that is helpful. Thank you
