Rated 4 out of 5 by from Love the pack - straps + back panel could b imprvdI was scared this bag was going to be huge on me (5'6 and replacing Blitz 30) but the Ranger Green somehow blends the size/aesthetics. The bag looks way better in person than depicted on the site. I am in love with the bag and almost scared to take it out as it was a considerable investment for me. It hasn't left the house yet but I already pulled some of the fabric from the straps' inside padding by coming into contact with some velcro web keeper I made and added myself to the strap pull ends. The main area of improvement would be to make the straps and back panel a solid material instead of something so delicate.

Rated 2 out of 5 by from DisappointedBeen using this bag for two months as DD to carry work items to/from sites, zippers and overall construction are great. Shoulder straps are so unbelievably cheap for a pack in this price range it's hard to comprehend. They've began fraying and will have no padding inside of 6-8 months by my estimate. This pack does not see extreme duty or any serious miles, hopefully this is an isolated Q/C to the 3 DAP. No matter how good the rest of the pack is I shouldn't have to take it out of the rotation to have shoulder straps repaired prematurely after hardly any real use.

Rated 4 out of 5 by from Love it, butA few months back my 3DAP was stolen out of my car. I carried it for over 8 years all over the world. Great pack. I bought this most current model as a replacement. I like the new cordura (lighter) fabric, zippers, and laptop pouch. However the shoulder straps lack the robust padding of the previous models and does not have the nice organizational pockets in the too pouch. Mostly for the shoulder straps are why i only gave it four stars. I also highly recommend MR put a zipper or velcro pocket where the plastic back panel is so that the user can quickly change out this panel for one that has aluminum or composite stays. Combined this with more robust shoulder straps the pack can easily accommodate 35 lbs or more comfortably.

Rated 3 out of 5 by from Ergonomics could be improvedThis pack is about the most comfortable tactical backpack one can find, but in comparison to hiking pack brands, one can notice some obvious ergonomic flaws. I had to remove and resow the load lifters closer to the edge , which made a world of difference in shoulder comfort. The plastic backplate is pretty uncomfortable in any situation where I was moving around. It only seems to fit when I stand rigidly, removing it feels way better.

Rated 3 out of 5 by from Another strap-related reviewI have a 2-3 year old 3DAP- used very rarely, maybe only 5 times with +20 lbs. The shoulder straps are shot in terms of the foam and comfort. I also have a 2016 Philippine made Sweet Pea whose straps are MUCH more substantial. I really love this pack and am super bummed that in their quest to enter the EDC and civilian market they've lost sight of what made them special. Gone the way of so many other US made brands. Listen to your customers!

Rated 5 out of 5 by from Bomb Proof packThis pack does everything from SAR day ops and jumping out of planes to carrying my laptops around town. I beat the crap out of my stuff and this bag has never failed me. My only complaint is that the waterproof zipper material has been chewed up by the zippers a bit but that's because I tend to tear the bag open. It hauls heavy loads surprisingly well, while still holding its shape when empty. I've owned it for a little over 3 years now, and although its covered in blood stains and battle scars, it shows no signs of slowing down anytime soon. This is the best do-it-all bag you can buy and will carry anything you need it too in any condition.

Rated 2 out of 5 by from Good pack but quality has dropped.I bought a used 3 day Assault about four years ago or so. It was so well made that I decided to spring for a new one this year. New shoulder straps feel like a wal mart pack now. Fewer organization options. Quality went down but price went up. If the price were lower I'd rate it a couple stars higher.

Rated 1 out of 5 by from Never meet your heroAs a long time fan of Mystery Ranch I always wanted this pack, I saved up and finally brought two hoping they would last me many years. As other people have said the straps are terrible, thin and uncomfortable. I contacted the US and UK customer service and because I live in the U.K they where not interested in helping me to upgrade the yoke to the new updated version, as the bag was so uncomfortable I had to get rid of them. A massive disappointment.
