Question: What are the sizes of the two velcro areas?
Document: Where do I begin, this thing is amazing very strong and an amazing value as well. All of the compartments are very organized and have tons of dividers and organizers. The material itself is very strong and there are MOLLE straps everywhere they could put them, there are even strap holders for the bottom so you can strap an ISO Mat to the bottom or maybe a small tent. This pack is better than anything I have ever been issued in the USMC and it has 2 Velcro areas stitched onto the front which are perfect size for a name tape and flag or flight patch.
The sewing is perfect - I haven't seen a single loose string. I've even used it as checked luggage a few times, and other than scuffs on the bottom, it's in perfect shape. * Versatility - MOLLE straps everywhere. MOLLE on the bottom to strap a sustainment pouch or sleep mat. Cutouts with velcro covers for Camelbak hose or radio antennas\hand mic cables. * Comfort: at one point I had this loaded with two AN\PRC-117G radios, four batteries, four antennas, a TACSAT antenna, several extra mags, and a Camelbak - and it was still comfortable.
This ruck makes a great 3 day pack. Its almost infinitely configurable. Its covered in molle webbing o0ver the entire exterior and the inside is eat up with pouches, strapping, pockets of all sizes including some made to secure 4 30rd M4/M16 mags internally. The construction is superb. Ive used and abused mine for three years now with negligible wear and no failures. The two zippered side pockets are great for quick accessible needs. I put my camelbak 3L reservoir in one just because it fits like a glove there and its a helluva a lot easier to access then the internal pouch 5.11 made for a water bladder.
In order to run your drink tube from the bladder pouch you first run it into the main pouch, past the sunglass pouch to either side and then up through a hole in either side of the drag handle, this takes up precious tube length and it seems silly to run the tube farther away from you than it started. And the bladder pouch has a double zipper that closes to both sides so if you wanted to just run the tube out of the zipper it would either come out of the side or you would have to leave the pouch about half open.I ended up puting my bladder in one of the side pouches and just running the tube out of the top of the zipper, a two liter bladder fits pretty well, and I store flat stuff like my poncho and poncho liner in the bladder pouch instead.I store my cooking equipment in the other side pouch, it's about the perfect size for a 1-liter jetboil with an extra can of fuel on top, in addition to the one inside the jetboil.The large front compartment is a good size and has many pouches of various sizes for storing smaller items.
Large enough for any survivalists needs. Has a huge variety of pocket sizes, zippers mesh and all the goodies needed for a long and/or heavy haul.
This way I have an EDC and a main pack that work together. In any case, the Rush 72, on top of having an excellent set-up with all the compartments, pockets and compression areas, also impressed me a lot with it's look and quality of construction. A lot of backpacks say they're heavy duty or built to withstand abuse.. This one's the only one I've handled that has convinced me.
This bag has a place for everything. Big and roomy, well constructed and has attitude. I gave it 4 stars as i think the manufacturer should have added a velcro closure to the front flat pocket. The adjustment straps don't seal the middle of this storage pouch. My second 5.1.1 bag and will probably get more.
It also has the chest buckle that you see on large camping/hiking packs. Some packs have areas to store the belt and chest buckle... this does not. It would have been nice if they had been stow-able or removable. They can sort of get in the way if you just like using the shoulder straps. I'm sure a DIY person could adapt them however with the addition of some buckles for quick release.The pack itself just to warn you is heavy on its own. It is built rugged however, that is clear.
I didn't like it at first but it turned out to be really useful when I was late to class and was in a massive hurry)-More pockets than I will ever need (there are multiple pockets and sectioned areas on the interior that are extremely useful and range in size from small to fairly large)Cons:-Shoulder straps are a bit of a pain (the straps are super sturdy, which is nice, but they make putting the backpack on feel a little awkward. I usually bring the pack up above my head and but both straps on at one time.
Every Day Bag: Positive: You can carry EVERYTHING you could possibly need. Books, a change of clothes, blanket, helmet, it will all fit. Everything you put in this bag will just be swallowed up like it's bottomless. And the number of storage compartments and zippered areas is awesome. I could seriously live out of this bag. If you aren't carrying a lot then you can really cinch in the straps to make it compact.Every Day Bag: Negative: Heavy. Big.Overall: Build quality is top notch.
Answer: yes
