Hazard 4 Defense Courier Diagonal Laptop Bag Review

tl;dr – 5/5, awesome laptop bag, treated like hell for a year, still going strong

A little over a year ago, at the NRA Annual Meeting in 2016, I was in desperate need of a new laptop bag. Scouring different vendors on show floor yielded little result. Everyone had similar versions of the same bags, covered in MOLLE and sporting a myriad of pockets, but none of those I visited seemed to have a dedicated laptop bag.

On the last day of the convention, Erin pulled me over to the Hazard 4 booth. She was eyeing a very nice looking poncho and had brought me over to see if they could find me another bag.

The Defense Courier bag jumped out at me because it was distinctly NOT tacticool. It was a functional laptop bag that would blend in well in a corporate environment. I wanted the bag, not to show off at the range, but to actually use for work and hump gear from jobsite to jobsite. Some jobsites are not exactly permissive when it comes to the right to self-defense (some for legitimate reasons, others for purely political).

I didn’t just want to post a review right after I got the bag, though. I wanted to see how it actually held up. So here’s my report on the bag after over a year of hard use. It carried my tools and laptop every day of work and several for play. It wasn’t babied – it was thrown into the back of my truck, drug on the ground, dropped, and used roughly.

The front has a nice panel of loop material for patches to hook into. Minor complaint that the Hazard 4 logo is permanently attached and can’t be removed. A large enough patch can cover it up, though.

The smooth material has garnered a few scuffs – mostly from encounters with rough concrete. It’s structurally intact, and cosmetically it really should look far worse than it does for what it’s been put through. The buckles still work flawlessly, despite the right one having been slammed in a car door on accident.

The large front strap fits well when slung across the back. The padding doesn’t move and slide around like some designs, which I like when making longer walks with the bag (I recently worked in a convention center that took over 30 minutes to cross from one end of a hall to the other). There is a second, stabilizing strap that hooks into the main one, but I generally don’t make use of it and keep it tucked away.

The main compartment is huge. It’s tempting to fill it with too much stuff. While the bag can hold it, it gets cumbersome to haul around too much weight. My 15″ laptop fits snugly in the protective pocket and has been well preserved despite my treatment of the bag. The inner, side pockets are seemingly tailor-made for holding a power strip and the laptop charger. The power strip doesn’t stick out of the bag, when it’s closed it is a perfect fit.

A front zippered pocket holds pens, cables, and other random tools. The pouches attached to the front MOLLE are each an extra purchase from Hazard 4. I use them to keep cables, battery packs, and an extra pair of glasses.

This is the only other significant damage I can find on the bag. A couple of threads coming loose on the laptop sleeve from heavy use.

It’s an expensive bag. MSRP is $156. I got it on sale at the show for $120, and the extra pouches for $10 and $15. I have to say it’s absolutely worth it, though. A year of hard use and it hardly looks used. I heartily recommend it. I only wish they made a version for larger laptops as well.


MAG-40, Take Two

Erin, psyching up and hydrating before her final shooting qualification

I spent the week up in Live Oak, FL at a MAG-40 class. This time, I was helping out as an instructor! The old adage really is true, if you want to master something, teach it. Walking new shooters through the techniques and watching them really helped me understand things that I hadn’t thought about before. It was also quite a lesson in how to teach, as the other instructors were eager to assist me in assisting others.

The most memorable moment for me was the Exemplar Drill. The student aims at the target downrange while the instructor uses pressure with their finger on to of the student’s trigger finger to “pull” the trigger. It’s to help give the student a feeling of a smooth rolling press. It also helps them see any issues in accuracy relating to trigger pull. First run through is dryfire, 100% instructor pull; Second run is live-fire, 100% instructor pull; Third run is 50/50 instructor pull – student pull; Final run is 95% student pull, 5% instructor pull.

I had one student, a gun owner of 6 months, that was shooting all over the target. Everything was on paper, but it was a 12 inch group at 7 yards. The first live run through the exemplar drill had him shooting 2 inch groups. “Hot Damn. This stuff really works!”

NRAAM 2016: Saturday Morning

Better than cartoons, Knives!

Ka-Bar sold out yesterday, they were offering sporks 3 for $10. Their booth was the first place I went this morning. The deal was changed to $5 each, but still less than the $7 MSRP. It’s all plastic, though I don’t know the specific kind, no metal that I can tell (There may be some hidden in the handle, but that’s just a guess. I’ll have to test when I get home).


NRAAM 2016: Thursday Night

Picked up our badges early, grabbed some merch at the NRA store before it sold out, and then headed downtown for some dinner. A local pizza chain drew us in with a discount.




Oddball tells me the deep dish pizza is the best in the region. Jack and I stuck with non-breaded wings to keep to our low-carb diets.

I Made a Thing: HOTAS/Chair/Desk

I play Star Citizen a lot. ( It’s a new space-sim online multiplayer game still in alpha with six degrees of freedom when piloting space craft and fully simulated Newtonian physics. It’s being made by Chris Roberts, the creator of Wing Commander. Check it out if you’re into that sort of thing. ) You can play it with just a keyboard and mouse, but other controls are much more fun and immersive. I needed a more ergonomic solution to using my Joystick and Throttle. Leaning over my desk wasn’t comfortable and couldn’t be done for any real length of time.
