Initial review and first impressions as of July 7th 2018:
I was definitely a little worried ordering clothes online without being able to try it on at a brick and mortar first.
Unfortunately for old guys like me who are accustomed to going to a store, trying something on before buying, this seems to be the trend and its here to stay.

Quick facts regarding my own purchase: I am around 5'10" 190 pounds. Nearly zero muscles (not proud of that). Above average flab (flabulous?). The "Large" size fit me like it was taylor fitted for me. My size is pretty average in almost every aspect, and most of the clothing I buy pretty much fit the way they say it will.

Quick Review:
Materials feel thin and average (too soon to really know: no stars deducted at this time). Jacket overall along with pockets are single stitch and I've already had to "reinforce" a velcro piece (wasn't thrilled about that: one star deduction). Very pricey (but I have not found a better option: no stars deducted). Zipper seem average to inferior (all have held up as this item is around 2 days old: no stars deducted).
Potential buyers should be aware that this item carries your weighted items differently from what you could be traditionally accustomed to (will go over in long review). Overall, I like this item. If it were around $39.99 - $49.99 I would whole-heartedly recommend this item. At $175.00 as of July 7th 2018? Hm... It is pricey, but to find an item in this category to satisfy these same requirements, you would be hard-pressed to find a better item!

Long Review:
I purchased this item as I hate having to empty out all my pockets when I go through the TSA when flying, and from my concerns about pickpockets in the countries I have on my itineraries. My last trips left me quite exhausted having to constantly be aware of such issues. Pickpockets know where all the traditional places a person keeps wallets and valuables, so I expect they are naturally honed to filch from these spots (like muscle memory). When you move things around a little, it naturally gets a tiny bit more challenging - so since I believe that ALL people should "work" for their money. My potential pickpockets should too.

FIT:
I was very pleasantly surprised with the fit of this coat. Obviously there were concerns about it bulging out in abnormal spots with all the items fitted in, so I did start packing things in to see how they fit and how it would look. Definitely did not want to look like I was carrying a lot of goodies under my coat. I purchased the black color to minimize the appearance of obvious bulges, and I believe that this does work somewhat. Items placed into the jacket did have minor protrusions, but definitely much less than I though they would have. If you want the jacket to look more fitted, the bulges will be harder to conceal. If you are ok with something a little more baggy, I imagine you will have more room (and comfort) with your items. I'm not sure how a larger coat would look in terms of droopiness - one of the cons of not having a brick and mortar store to experiment with.

MATERIALS:
The fabric felt somewhat cheap for me. Obviously it is not hard, durable canvas or some sort of "ripstop fabric" (tm?). However, there is nearly no "breaking in period" and the fabric is soft enough to "droop" and not get caught on certain angles to give a smoother non-bulky. non-angular appearance. The fabric is soft and fuzzy on the outer shell and thin and cheap silky feeling nylon-ish material on the inner parts not the more durable woven ballistic nylon that we can find on our bookbags. There are pros and cons to having both (pros: it is light, breathable, and sleeves are smooth to get into and out of. Cons: it seriously feels like it will not last).
Velcro closures feel somewhat sub-par. Zippers are a mix. The zipper being used for the large inner back pocket feels cheap, and the surrounding soft cheapy nylon fabric will get caught (and further ground/cut up) by the zipper teeth. The zippers for the side pockets feel a little more substantial, but not like a solid brass ykk.
Buttons seem fine. I like that the buttons have something like a plastic "spacer" between the metal snaps and the fabric. But I have encountered much more solid and high quality buttons - So all in all: buttons, zippers, fabric... they all seem pretty average. The velcro... meh (I've already had to reinforce one, so I'm biased against it). Again, not sure that it should command the $175.00 price tag it currently has on Amazon.
As mentioned before, jacket is single stitched throughout - (I prefer double or triple for jackets) - which again feels like it could be improved upon.

WEAR:
This jacket is light and comfortable to wear without any items inside. The reason: see above. However, there is one thing that you should take note of: the weight distribution for your items are being shifted to the upper-front portion of your body. It is advertised as having a "weight management" sort of rigging - but the truth is, it basically all goes to your shoulders and back.
For people who have backpacked before, you all understand that a good bag can significantly reduce your fatigue when you are walking about. The way that many of these "good" backpacks work, is they distribute the weight to your hips - so it is OFF your back. It doesn't mean that your back cannot take any weight, but it should take less. If you are still planning on carrying a good old messenger bag or some other bag, it would be a good idea to try that on with your jacket (fully loaded up) to see where the straps are pressing.
Just keep in mind that wallets, phones, spare change/keys etc. can sometimes be in your pant's pockets. Which means that your hip is carrying all that weight through your pants.
Also, since most of the pockets for this jacket are located in the front (inside), I found myself having to stand differently (slightly pulling myself back). Anyway, I found it new and somewhat uncomfortable - but mostly because I was not "used to it." I'm sure it will get better with time/routine, but I cannot say for certain. Anyway, it is something for you guys to consider before purchasing this item.

All in all, you see that this item is still rated quite highly at 4 stars for me. It almost seems that I have more critism for this item than compliments. But it is not true. I actually really like this item. I think that it is an extremely smart item and provides additional options that would otherwise not exist. I like the design of this item and the careful consideration its makers have put into building this jacket. Can it be made even better? Sure can! Is there anything out there right now that is better? No idea! Let me know if you do!

I plan on using it as part of a larger hybrid system. I'm not sure that I would carry ALL my items in this coat. I'll probably still keep some weighty items in my pants (such as my phone and wallet - because there is just 'so' much money in there... in the form of pennies), but it is really nice to know that I CAN put more things in my jacket and potentially have everything "in one place" if I wanted it.

I will need to put more time into its use before a better review can come about. I do not recommend shying away from this jacket. I am currently rating it 4 stars because even after all my initial thoughts, I really like this jacket!

I purchase all these items with my own pennies. If you found this review helpful in any way, please share the love! Click on that thumbs up icon!
