Honestly I was put on to this bag by Escape from Tarkov, and finally purchased it prior to being deployed. The internal pouches are a good size, for clothing and other items, with only the center pouch being optimal for larger items. I could fit 2 pairs of size 14 boots in the middle pouch, and tons of clothes in either side pouch, as well as the zippered pouches on either side. The outside pouches on the front are very well proportioned as well, with a seemingly purpose built helmet and earpro bottom pouch and a first aid kit pouch on that flap. The solid frame is also very well designed and performs as you would expect it to. The inbuilt water shield is also a huge bonus.
Some of the outstanding features are the quality of the zipper pull tabs, the amount of padding around the hips and back and the molle. Holy smokes there's so much molle.
The best part, and the part I used literally every day, was the claymore pouch literally detaching and become a waist bag. People definitely comment about the fanny pack, but it is the most expensive, and probably best, fanny pack you will ever use.
I left a star off because dealing with customer service was rough. They were quick enough to respond and mostly polite, but they were unhelpful, as once the pack had crossed the border, I was left in the dark, as no tracking information was updated, and it appeared as though the pack was stuck in Toronto for a week, causing panic where I had to reach out on my own accord to several organizations to receive an update. This is uncalled for when purchasing a pack of this caliber and price.
Otherwise, I'd recommend, and I'd buy it again.
