- Reviewed in the United Kingdom on 6 February 2021Size Name: 17.3 inchesColour Name: BlackVerified PurchaseI wanted a lightweight bag to act as a portable home filing system for the most important documents of a household to replace the heavy metal box type. I searched the huge selection on Amazon and decided this Kroser 18" looked the one.
Delivery was immediate and I wasn't wrong in my choice. Beautifully made and sewn. Material strong and zips of a very good quality. I like the expansion giving lots more room and just enough pockets so as not to take away from the roominess. I won't be using this to carry my laptop as it's not going anywhere ! but that space can also be used for additional file storage which is what I need.
This bag would also make a perfect overnight bag too.
I recommend this bag highly. My only criticism and it's not a criticism as such. I would have preferred a different colour to black. Every bag of this style seems to be produced in black. But that aside, it's a fabulous bag and I'm immensely pleased with my choice.
- Reviewed in the United Kingdom on 15 September 2024Size Name: 17.3 inchesColour Name: BlackVerified PurchaseI needed a bag where I could not only fit a laptop in but also enough space for a large folder plus accessories for my university course.
I was a bit apprehensive because in the past I'd purchased other bags to find they were a lot smaller than advertised. Luckily this one has more than enough space and seems sturdy.
- Reviewed in the United Kingdom on 23 April 2024Size Name: 17.3 inchesColour Name: BlackVerified PurchaseI Dont ussually write reviews as I like to experience product first...
I never had work/laptop bag before.
I had this bag for nearly 9 Months now...
I carry it everyday with laptop, phones, chargers, lunch, spare socks paperwork pens etc..
It never lightly packed...
Bag is with me on short journeys, its with me in the van when Im on the tools etc...
Its not really taken care off but the bag takes care of me and its contents.
Despite of heavy use no zips failed, no straps/hoops broke, no tears rips etc...
Well sized even for a short trip.
Really recommended. (I Hope it wont let me down now after I recommended it, haha)
- Reviewed in the United Kingdom on 13 November 2024Size Name: 17.3 inchesColour Name: BlackVerified PurchaseI bought this to replace my old laptop handbag. When it arrived looked a bit smaller than the old one, but surprisingly when I started to put in all my stuff, I could put more into it than into the old one! Good product and really spacious, shoulder strap is very good as well. I can really recommend.
- Reviewed in the United Kingdom on 7 May 2025Size Name: 17.3 inchesColour Name: BlackVerified PurchaseBought this for my laptop to make it easier for me to carry around with me on my travels. I will say that the zips don't seem to ever get caught on anything which is a plus. I do think that the may be water proof as it says but I wouldn't completely say that its best so i do try my best to still keep it out the rain. The bag does also have some good padding so it can definitely help when walking and knocking the bag across the walls. For the price of this I would say its quite good quality very good use for its purpose of looking after my laptop and other equipment and also the design of the bag makes it look nice and casual to go to work with.
- Reviewed in the United Kingdom on 8 December 2024Size Name: 17.3 inchesColour Name: BlackVerified PurchaseLovely bag, great quality with lots if space in all the compartments, a great replacement for my old one.
- Reviewed in the United Kingdom on 11 September 2023Size Name: 17.3 inchesColour Name: BlackVerified PurchaseThe bag arrived in good time and it was just what I needed. In fact for the price it was much more than I expected. I am very pleased with this product and would recommend it to anyone who needs to tuck everything away in it rather than weighing done pockets. Plenty of room and great for much more than my laptop,

LEVALOTEReviewed in France on 8 June 2025
5.0 out of 5 stars Très prtaique!
Size Name: 17.3 inchesColour Name: BlackVerified PurchaseJ’utilise ce sac KROSER depuis quelque temps maintenant, et j’en suis vraiment satisfait. Il est assez grand pour contenir un ordinateur portable jusqu’à 17,3 pouces, mais aussi des dossiers, un chargeur, une souris et même quelques affaires personnelles. Il est bien pensé et très pratique pour le travail, les études ou les voyages.
Ce que j’aime particulièrement, c’est qu’il est imperméable, donc pas de stress en cas de pluie. Il y a beaucoup de poches, y compris des compartiments protégés RFID pour les cartes bancaires ou les papiers, ce qui est rassurant niveau sécurité.
Il peut aussi s’agrandir si on a plus de choses à transporter, et la bandoulière rembourrée est confortable même quand le sac est bien rempli. On peut aussi le porter à la main avec ses poignées solides.
En résumé : un sac solide, pratique et sécurisé, parfait pour les déplacements pros, les cours ou les voyages. Très bon rapport qualité-prix.
