ZINZ Spill-Resistant Slim and Expandable Laptop Backpack 15, 15.6 , 16 Inch Sleeve with USB Port, for Most 14-16 Inch MacBooks Surface-Books Dell HP Lenovo Asus Computers (Blue)

After purchasing and returning a pretty bad laptop sleeve, I decided to find a cheap laptop bag to fill the void in between receiving my 'proper laptop bag' early in 2023. The bag has since nice compartments for your charger and small accessories. I like that you can add a drink bottle inside as well.The only thing I worry about is the lock holding down the backpack strap. Seems it can lift up quiet easy, which could result in the bag just dropping to the floor very fast. I'm going to see if I can add some extra reinforcements to it to prevent this from happening. The zips on the bag are rather cheap looking / feeling, so I'd try and be careful when using them.There is plenty of space in the bag for my 16" MBP, though have read reviews it's too small for a 17" however. Would recommend this bag over a laptop sleeve anyway, and given the cost of it I'm more than happy to thrash this about without a care in the world.

High quality on the zippers to open and close repeatedly. Closes tight so a bit little water resistant for contents.Looks pretty stylish, handle is also thick and strong so I’ve also been carrying as a briefcase.When expanded, functions as a pretty normal backpack and fits a lot. Switching it back and forth to make wider or narrower is very easy and quickCame with a USB attachment to run cable from inside while wearing it to outside - but not really sure what it’s for (recharging your phone from a battery pack in backpack maybe?)

Utilisé en quotidien pendant 8 mois, les bretelles ont finalement lâchées sous le poids du sac chargé lors d'un voyage en avion en cabine.

looked quite a bit for a laptop/light-travel bag - one that could be easily carried empty within a larger heavy-duty travel bag. found most bags to be either way too light, or way too heavy.this bag fits the bill almost perfectly: very small and light footprint when empty (so it can be packed inside a larger, heavy-duty travel bag); expandable to carry laptop and some small items after the "heavy" travel part (e.g., travelling to the office after flying).

Update: I used this bag everyday for 3 months& a seam popped on the shoulder strap which has started fraying. Also, had to replace the hardware on it straight out of the bag.For the price, there’s a lot of good things going on in design, styling, features, and function. Mostly good, some downsides.This is not designed for heavy or thick laptops- definitely meant for lightweight laptops or tablets. Would not trust use this as a backpack for heavy loads as is- with modifications it could be good. Will likely use as a lightweight daypack for travel or personal item.This bag has so much potential to be great in the design and styling, but there are obvious quality issues with the plastic “hardware” - a clip broke straight out of the packaging from shipping without any weight in the bag. Zippers are just okay. They snag a bit on each other and extra fabric in the expanding section when unzipping. Requires a little finagling, but otherwise okay.Laptop section is lightly padded and lined with a soft sort of microfiber lining. Lining is about 10.25in/ 0.5cm. Designed with slim laptops or tablets in mind; thicker laptops for gaming and such will probably struggle to fit in this sleeve. No stretch or give in the material on the external dimensions of this area. About 15 in/38 cm long, on the diagonal measure it is about 17in/43cm.The double water bottle pockets are a nice feature when expanded. Won’t hold a Nalgene, but I was able to squeeze 26oz/750mL insulated bottle into the pocket with the bag empty. Bottle circumference for reference is 9.75in/24.7cm by my measure. It was a very tight fit, but it just fit. Mesh pocket was stretched to its full measure. Will probably utilize one for an umbrella/ rolled rain jacket or sunglasses and case and the one one for water.External pockets- both are flat. Top pocket is about 6 in/15 cm. Bottom is about 7in/19cm. Rear pocket (strap storage) is flat & 13in/33cm deep. Rear pocket could hold folders or maybe a small water bladder if you are VERY serious about hydration. I will probably place a compression packing cube with a jacket in there to serve as additional back padding if carried in “backpack mode” and easy access.The pass through port has USB A, USB C, and audio ports. They all worked on first use. We’ll see how the hold up over time.Trolley strap/ suit case handle pass through is about 9in/23cm.Minimal internal organization in the expanded internal section. One main pocket with a stretch pocket on the back for a folder or maybe a tablet. Fold down flap for stability on the bottom, but doesn’t seem like it would be very sturdy. I’ll probably reinforce this on my own. There are flaps on the side that keep this bag from fully opening clam shell style, but could be modified for that effect if desired.I would not try to load this down or over stuff this bag in “backpack mode”. I don’t think the zippers are sturdy or durable enough for rigorous or heavy use as a backpack. Straps and back have like zero padding which would make uncomfortable for long wear.Lighter loads are probably best based on the materials used.The design is pretty cool, I wish more effort had be put into higher quality hardware on the bag. I read other reviews that mentioned bad hardware. I’m going to replace the plastic parts with metal D rings and clips.Using for a trip at the end of the month. Will probably add on top of my rolling bag and not carry as backpack. Plan to use it for easy access items to be checked at security and in flight.
