5.11 Tactical RUSH24 Military Backpack 37L - MOLLE Compatible Tactical Rucksack for Outdoor Adventures, Hiking & Travel - Durable Army Style Pack (Model 58601)

*Update 11-30-15*I went on my day trip to Universal Studios in Florida. I spent the day at both parks on my feet with the bag on my shoulders. My back was not at all sore at the end of the day. The when the bag was completely packed from buying crap I didnt need it was difficult to fit it into the park lockers. However, even when loaded down it fit fine under the seat on the airplane.One thing I have found is if I am going to be wearing the bag for an extended period of time with my laptop inside of it, if I put it in the main pocket in one of the pouches it is easier to carry than if I place it in the water bladder pocket. I love this bag more every time I use it.I am on day 3 of this bag. YouTube has hundreds of reviews of this bag. And they all pretty much state the same thing. The bag has a lot of space and lots of organization. I spent a few days watching videos of different load outs and different views on all of the pockets. I ended up with this bag because a few friends recommended 5.11 as a great company that puts out a great product.I started my search for a new backpack due to a trip that I am taking in a couple of months. I am going to Universal Studios, I will be on the road for a little under 24 hours. I need a bag that I can pack a change of clothes, a Nikon D7000 and two lenses, a 13'' MacBook, an iPad mini, and food. The world of backpacks is wide and varietied, (<---- That might not be a real word.). I have an Eddie Bauer backpack that would be perfect for my needs. But that bag is about 7 years old and I can see light coming through tiny holes in the bottom of the bag. I wanted a "military" style bag. But I am not, nor have I ever been in the military and did not want to come off as someone pretending. So that means I did not want a camouflage pattern. The bag also needs to be able to be a carry on bag for plane travel. These are just a few, but main concerns for picking a new bag.Here will be a list of how it fits my needs based on the list above.1) The main pocket will hold two sets of clothes easily.2) There are several medium pouches in the main pocket. I will put two lenses in one pouch and the another will hold the camera body.3) The bag has a hydration pack pocket. I will not be using a hydration pack with this bag as I use a camelbak when I am biking. It holds my laptop with plenty of room. Many reviews say that you should put some form of a closed cell foam into the bottom of the back to add some extra protection.4) In the front admin pocket there is a zippered pocket that fits my iPad mini with water proof case with a little extra space.5) I like to pack little packs of animal crackers and cheeze-its and Cliff Bars, those can fit anywhere.I am using everything listed above except for the clothes as an "EDC" (Every Day Carry) bag. Even with the clothes I do not think I will have this bag filled more than half way.I have added a few add ons. The bag is built to be customized as needed. There is a pretty large amount of aftermarket support for this style bag. The bag has webbing to attach external water bottle holders, ammo pouches, general purpose pouches, map holders, holsters, and just about anything else. One of the things that I was looking forward too was the velcro patches. I added a few flag patches, USA and Maryland flags. I also put on some Star Wars patches. I bought a roll of double sided .5" velcro and added more places to put velcro patches onto the webbing. I went crazy with that actually. I put on two large carabiners from my climbing harness. And lastly to break up the sold black color I put about 30' of neon orange paracord onto the bag. I wrapped the grab handles in paracord. That helped to soften up the grip handle. I also made a couple zipper pulls out of the orange cord.A few future uses.I go camping a couple times a year. I will have no problems loading everything into and on this bag. During the warmer months I do not pack a tent. I use a small hammock. But even when camping in the winter when the temps drop down to freezing or below I will have no problem attaching my tent and sleeping bag to the sides and bottom of the bag. I can not attest to how comfortable the bag will be at full weight, but the yolk style straps are the most comfortable straps I have ever used.I will be using this bag to go rock climb. Whether I am climbing indoors, I can just clip my harness and shoes to the webbing on the bag. But this bag will handle a large volume of rope if I am climbing outside.As stated earlier, I do travel by plane for work a few times a year. It would not be a problem to pack for a week and not need to take a checked bag. I will easily take a large amount of clothing.One or two quarkie things.There are upper compression straps. There are no lower compression straps. Had I not been researching backpacks I would not have known any different. But when you do not load the bag completely you want the bag compressed as much as possible to keep the weight close to your body. This makes it easier to carry for a longer period of time. Not having the lower compression straps means the contents of the bag can spread out in the bottom. But you can purchase clip on straps that will work. I have seen them at a wide price range, as low as $5 and upwards of $35 and more. I am going to play with paracord to make something if it becomes a problem.Along the lines of the compression straps are a belt strap. I have used bags with these and they do help on longer hikes or climbing if your bag is loaded down. There are mounting points to add one latter. This is not by any means a deal breaker. Just it is not there.The arm straps are comfortable and they have a chest strap to help keep the pack centered on you while hiking. They work fine for me so far. I am 6'2'' and 210 pounds. Not a big guy, but not small. They use the webbing that is on the arm straps. The adjustments are about 1"-1.5" apart from each other. It has not become a problem yet. If it does, then I will use more paracord to gap the difference between built in adjustments. Paracord can fix anything I have discovered. It is almost as useful as duct tape.The bag is made of a heavy nylon, 1050d I think is the type. It is very stiff right out of the packaging. I am hoping it does soften up some. There is a hard plastic backing board in the hydration pack pocket. I am leaving it in there for now. As I have my laptop there I think it will add some extra protection.The only negative I have seen so farThere are drainage holes in the bottom of the bag. I understand the need for these. However, I know that I will set this bag on something wet, if not in small puddles. This is just inviting water into the bag. This is not anything bad enough to make me return the bag.Bottom lineI am very happy I bought this bag. For me, it is perfect for an every day use bag. Plus, I can use it to travel. It will get abused. I plan to update this review after my trip, and then again after a year or so. These reviews are so much better after the product has been used. I also want to get a body armor plate. They fit nicely into the slot for the hard plastic backer board. I do not plan on being shot, but it would be fun to have.
