TWIVEE
Backpack protective cover

The TWIVEE 2-in-1 backpack protective cover and rain cover is a versatile and practical accessory for travellers. The innovative cover functions both as a protective bag for transporting the rucksack on the plane and as rain protection during outdoor adventures.
The flexible size of the cover, which covers a range of 60 to 110 litres, allows it to be used on a variety of backpack models. The carrying function proves to be particularly practical as it allows the rucksack to be carried comfortably on the back, even when the cover is in use. The opening on the back allows access to the carrying straps, ensuring the functionality of the product.
Another unique feature is the lockable main opening, which offers additional protection against theft. Furthermore, the case is check-in compatible and is accepted by all airlines, making it an ideal companion for air travel. An integrated document pocket inside the case allows important documents to be stored safely.
The material quality of the cover ensures protection against both dirt and rain, making it an indispensable companion for any journey. Although the cover is extremely robust, it is still lightweight and easy to handle.
The TWIVEE backpack cover offers an outstanding combination of functionality and safety, making travelling with a backpack much easier.

The first impression of the TWIVEE 2-in-1 backpack cover is thoroughly positive. The cover is supplied in a compact, resealable bag, which is ideal for storage when not in use.
On first inspection of the product, the high-quality workmanship is striking. The seams are neatly finished and extremely stable. The material is extremely hard-wearing, yet lightweight. The well thought-out details, such as the lockable main opening and the integrated document pocket, also deserve a mention.
Another advantage is the easy handling. The cover can be easily pulled over the rucksack and adapts perfectly to different rucksack models thanks to its flexible size. The ability to carry the rucksack comfortably despite the cover, which is made possible by the openable back, is rated as extremely positive. Overall, the TWIVEE backpack protective cover leaves a very good first impression, both in terms of the packaging and the contents, both of which are described as high-quality and well thought-out.

The 2-in-1 backpack cover from the manufacturer TWIVEE appears to largely fulfil its advertising promise. The workmanship can be consistently described as high quality, and the functionality of the cover is also perceived as versatile. The robust material quality and precise seams ensure reliable protection against dirt and rain, meeting the needs of outdoor enthusiasts and frequent travellers.

*Themaximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.1 stars. In some cases, the quality of the seams and zips are criticised. On the other hand, the elegant and functional design and versatility are emphasised positively. In our practical test, we were able to confirm that the well thought-out and functional design of the protective cover was well received by customers. Consumer criticism of the protective cover’s seams and zips is only partially justified.

Prices of up to €55.00 are charged on the Internet for equivalent products. Very cheap products are available from as little as €9.99 . With a price of € 29.99, the TWIVEE backpack protective cover is therefore currently in the middle price segment. For the quality and performance received, the price-performance ratio is very good.
