The Midrange bag has been my work briefcase / bag for 7-8 years now. The quality is on par with Land's End or L.L. Bean, high quality zippers and Velcro, ballistic nylon, etc.
They have lots of other really interesting products if you look through the site. I have some of their portable tools, and they have excellent prices on real USA- made paracord which of course is equal to gaffer tape in usefulness.
