Al usar el equipo se siente muy cómodo, ergonómicamente se ajusta perfecto al cuerpo. La textura se siente suave y es de muy buena calidad. La distribución de los compartimentos son de gran utilidad y bastante espaciosos.Arrived quick and seems nicer than expected ! Will try it out on Aug 6th ! But so far, seems awesome !On the included "Thin Blue Line" patch:At first I didn't really want it as for the past several years it's been misused as a symbol of police privilege by a certain type of people. However on a certain day early in January 2021, those people proved that they don't actually support the police when they were willing to beat officers to death. Personally, I wouldn't do that, and they've lost their right to wear the symbol in earnest.Now about the actual bag.Good things I've noticed initially:-thin profile but spacious main pouch and secondary pouch. The small pouch is also lined with a nice material.-the reflective straps are awesome since I'm out at night in the street a lot. I'll probably add more. Also the sternum strap is fully adjustable and removable, as is the hose clip for the shoulder straps.-There IS a passthrough for the hose, I don't know why some reviews said there isn't.-The bladder opening is big enough for me to fit my hand in, great for cleaning!-Bladder was super clean and yielded nothing other than crisp water taste.-Hose is removable and bladder stops water from flowing when the hose is detached.-Classic American FlagAfter first test:-Seems pretty comfortable against my back.-Actually ventilates a bit.-Insulation works great.-Could use better shoulder support. The previous bag I returned actually had adjustable straps over the shoulder straps that added support, but I don't think most backpacks have this.Things I don't like:-FALSE MOLLE D: the molle style straps around the lower section of the bag are not vertically spaced as close together as true molle, meaning you cannot make as secure a weave with any extra pouches you may want to add.-The devicive use of police symbolism to sell "tactical" style gear to certain demographics.I'm considering a second.Anyone who has never been in the Army, Marine Corps, or otherwise, you might want to videotape a slower explanation on how to put all the pieces together!!!! The video online is just some macho guy telling which one uses or would purchase, not a great deal of help to anyone else, right?This is a very well built hydration pack. Its easy to use and the backpack not only looks great but has plenty of space even for an extra bladder or other things you want t carry. Highly recommended.Reasonably well made. The hydration bladder uses vinyl tubing, you'll want to replace that with silicone tubing as algae will grow on the vinyl. The tubing is also extremely stiff in colder temperatures due to this. May need to be headed to remove it from the hose barbs to replace it.Great backpack! I got this backpack for day trips and commutes to school on my motorcycle as well as a day bag for hiking and I couldn't be happier. The size was perfect for what I needed and personally I don't feel fatigued from wearing it while I ride my motorcycle for my 30 mile commute. I added 2 molle water bottle holders to the sides that I purchased separately and put my own patch on it and now it's perfect. Been using daily for about a month now and hasn't ripped or shown any signs of defects. This bag was a great purchase for little money specially since it also came with the water bladder. I was hesitant as it had no reviews but overall I'm glad I made the purchase.I'm a confirmed bag hoarder as I search for the the perfect bag for my urban edc. This is almost the perfect size bag. It's a smidge too big height wise but perfect width and depth. I have two complaints. the molly webbing on the exterior is too close together for a good weave when attaching other pouches to it . The second is that when set down on its bottom it promptly rolls forward on to its front. This is highly annoying and makes getting into the pockets harder than it needs to be.Company contacted apologizing for missing flags. No harm. Really great quality on the bags. Thank you.The product says im to receive to 2usa flag velcro patches.I only received 1 canadian on each one.Disappointed that we didnt get the 2 as said in the product details.Other than that. Bags are great, nice thickness. Perfect size for our kids to use hikingGood quality and perfect size for my needs
