Customers praised this durable 28L backpack for travel and daily use, noting "excellent value for money" and quality materials. Fits airline requirements and holds substantial gear. Common concerns: laptop access when packed, small water bottle holder, and stiff fabric. Customers loved comfort, spacious design, and versatile features.
J'utilise mon sac à dos chaque jour pour me rendre au travail. Je l'utilise aussi en voyage, il a le format idéal pour tout. J'adore mon sac Military 28L.
Quality fabric, zippers and clips, lot of usefull space given its size. If packed correctly there is no problem with stability and carry comfort. The shoulder pads are wide and padded enough for 28l variant, but might be not enough for 44l version if packed with heavier items. I would rate it 5 star if the compression straps were a bit longer so they could be used to strap a roll of foam mat on the side. They could also use mirrored clips so the strap could be used as compression strap across the backpack, not only at the sides. They could be also used to secure shoulder straps when used as suitcase.
Additional tabs for straps at the bottom of the pack would be nice as well.
Just received mine in storm colour and i love it. It feels and looks amazing.
Bought one for my boyfriend who loves Yellow in my attempt to introduce him to this brand. Fits his laptop, climbing gear, 26oz water bottle. I bought Classic 28L honeycomb to match him
Lots of features for price point. Among the best backpacks for price I have reviewed.
The ultimate air-travel backpack for a personal item!
An excellent and reliable backpack, the only drawback is the inconvenience of accessing the laptop during security at the airport, or if you just want to get the laptop out when the backpack is full.
This backpack is pretty perfect. Comfortable, roomy, substantial…and it truly fits under the seat! I was delayed at the Dallas airport for 11 hours the first time I used it and basically had it on the entire time as I walked around (no wheeled luggage to maneuver) and waited at various gates. I was surprised at how comfortable it is - my back never got sore from carrying it. It is definitely my new travel companion.
Great backpack, own 3 of these now and well impressed with the quailty
Used it once and it’s so-so. Wish the backpack strap can be hidden/tuck away, water bottle pocket is useless, mesh/stretch material are better choice.
velka spokojnost
I have been really happy with this bag. It's extremely versatile. It can be used for daily commute, hiking, as a personal item bag on an airline. Paired with the packing cubes, it works really well for short trips on a budget airline. The MOLLE system makes it really helpful for camping trips or outdoor activities. It's comfortable, made with strong materials, and looks good.
The biggest fear I had was the water bottle holder. A lot of the reviews said it didn't fit larger water bottles. I think this applied more to old versions of the bag. I was happy to find I could fit my 40oz Owala FreeSip Sway in without much of a problem. It sticks out the top, but seems pretty secure in the pouch. The Owala FreeSip Sway has a tapered shape so it can fit in a standard cupholder, so that might help. A bottle that is wider all the way down might be a little more tough, but the stretch material seems pretty accommodating to me.
I'd highly recommend this bag to anyone looking for a reliable, good quality backpack for travel or everyday use. Great value for money. Love it.
⭐⭐⭐⭐⭐
Nice quality, fits well in the Ryanair backpack sizer. Good quality, this will probably last for a good while. Will reccomend to my friends.
Well built, looks good, airline personal item compliant. Good Product.
Great color.
Great stitching.
I wish the straps were better organized when carrying the backpack like a suitcase.
Overall, it's excellent. 👍
Entrega rapida muy conteto con cabinzero
Everything is ok
Great quality fabric, zippers and details!
Couldn’t be happier with my purchase. Highly recommend!
I got this bag almost 2 years ago, and it is still like the first day. I use it for my trips and my everyday activities.
I already have and love the military 36L, but needed something a tad smaller as well.
As my 36L, it's well-built, the zippers and sewing look sturdy, and the back panel and shoulder straps are well-padded. I am on the shorter side so YMMV, but for me the size is comfortable to carry.
I like that there are many more colours to choose from, so I got a green one this time.
I haven't used the molly webbing yet but I bought a water pouch that comes with a snap hook for a future trip ;-)
I packed it with the Classic packing cubes (one large, two medium), containing tennis shoes, light sleep clothes, flip flops, spare shirts, one pair of trousers, underwear, cables/charger.
I added a light laptop, a mostly empty toiletries bag (I probably won't bring it on future trips, but it gives a good idea of the space left on top of the packing cubes), a (thin) book and a travel game in the front pocket.
There was a little room to spare as well, for a couple more shirts for example.
The pictures feature a water bottle to show what size you can fit; it's tight and the bottle certainly won't fall off but it does fit.
The laptop sleeve is, to me , a good idea. Sure, it will be a little annoying to get it out at the airport (though with the packing cubes to make it easy to root around, from experience with the 36L, it's not that bad either) but between the back padding and the clothes, and the fact that the sleeve doesn't reach the bottom of the bag so the laptop won't bang on the ground, I don't feel the need for extra protection. Of course, given the size/weight constraints, don't bring your biggest, baddest, heaviest gaming laptop ;-)
Putting it right against your back also helps with balance when carrying the bag, and it doesn't make it fall forward when on the ground like it does with my ADV Pro bag, where a dedicated sleeve is at the front of the bag.
Packing cubes are a must to keep things tidy and easy to find and pack; there are no compartments so you're free to arrange things as you like.
The inner pockets are good for documents, glasses, cables, earbuds... or even toiletries!
I’ve been using the CabinZero Military 28L for a while now, and I’m really happy with it. The bag feels tough and well-made. The fabric is thick, the zippers are solid, and it just gives you confidence it’ll last.
The 28L size is perfect for me. It’s big enough to pack for a weekend trip but not so big that it feels bulky for daily use. The clamshell opening makes packing super easy, and the laptop sleeve is a nice touch.
It’s pretty comfortable to carry, even when fully loaded, thanks to the padded straps. My only small gripe is that there isn’t a ton of internal organization, just a few compartments, but I actually like the simplicity.
Overall, it’s a tough, no-nonsense backpack that does exactly what I need. Definitely glad I bought it.
I already have a previous model of this backpack in Absolute Black, which I use for my sport. For my every day actions, I wanted a second bag. unfortunately, the black ones were sold out, so I purchased the Mystic Green.
The inside of the bag is as I expected: 2 zippered spaces, of which one is mesh. The laptop sleeve is there as well, even as the spacious main compartment.
The front section has its molle webbing, which I find very handy to use for a foldable shopping bag or funny key rings.
The best upgrade however, is the larger pocket for a water bottle.
The only real downside is that the bag is pretty heavy and warm, due to the back protection. This is with both types (the old and new one). Still, this is one of the most versatile backpacks I know, so still 5 stars for it.
Which reminds me: the purchase of the second bag and the packing cubes didn't go very smoothly, but after a few days and a lot of emailing with the back office, everything was fine in the end. Thank you Suzie for your patience and real customer care.
Je l’ai depuis deux ans. J’ai fait plusieurs voyages avec, traversant à pieds plusieurs pays, je n’ai jamais regretté. Très résistant, solide, et très pratique. Je peux mettre le nécessaire pour des voyages de 14 jours ou plus. En avion, train ou en car, il se glisse partout et ne prend pas beaucoup de place. Je recommande.
Be warned: the galaxy color is really purple. I thought it was a cobalt blue or medium blue but it is just plainly purple. The pictures at the time were not really clear on it. The bag itself is amazing. Everyone I show it to is amazed for good reason. It is just really functional and amazingly spacious. I have converted multiple people. The one downside is not being able to access the laptop pocket more easily when fully packed.I would prefer to have a zipper to access it.
This bag is a must have / best go-to-Everywhere!
Ideal size to fit in all cabin airlines requirements, nice soft straps for your shoulders and superb design!
I have a Military 28L backpack and i love it! But there is one thing that would make it perfect, that would be if there was a compartment with a separate zipper for the laptop (like in the Classic Tech 28). It is hard to get the laptop in and out if you pack the backpack full. If the Military 28L had this external zipper pocket it would be 5 star. It is only a problem when i use it when i work (and have my laptop with me)
