Nebulus
Knitted hat RULES

The RULES beanie from Nebulus made a good overall impression in our test. The knitted hat is unisex and available in one size . It is available in two attractive colors, the timeless navy blue and the bright white. The hat is ideal for head sizes from small to medium. Unfortunately, it only fits a little tightly if you have a larger head circumference. Nevertheless, the knitted hat adds a stylish touch to any outfit and is an essential accessory for fashionable heads. In winter, it also keeps you pleasantly warm on cold days.

Advantages

✅ High wearing comfort
✅ Good workmanship and quality
✅ Pleasant fit
✅ Keeps you very warm

Disadvantages

❌ Cleaning by hand wash only
❌ Too tight for a large head circumference

RULES knitted hat in its product packaging

The RULES hat from Nebulus was delivered together with other products in a sturdy shipping box. The shipping box was undamaged and could easily be opened with a knife or scissors. The box was also optimally sized and filled to the brim. This helps to protect the environment, as not only is the amount of material required for the shipping box minimized, but the transport vehicles are also better utilized. Inside the box was the RULES cap in its product packaging. The product packaging consists of a transparent plastic bag in which the RULES cap was packed. The film is tear-resistant and not stretchable. The Nebulus logo is printed on the front of the packaging. There is also a sticker on the packaging with a barcode and the product name and size of the cap. There are warnings on the back that the bag poses a choking hazard. The information is available in four languages, including German and English. The bag has an opening at the top, which is sealed with an adhesive strip . If the bag is returned, it can be resealed with the existing adhesive strip. There is a thin layer of paper between the individual layers of the folded cap to prevent the material from rubbing during transportation. The RULES cap is very well protected from damage and soiling by the cardboard box and the plastic bag.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the package complete and does the manufacturer make it as easy as possible for me to use the product straight away?

Back of the RULES knitted hat

For our test , we received the RULES beanie in navy blue. In addition to navy blue, Nebulus also offers the hat in white. The dark blue color gives the hat a timeless look.
The upper part of the hat is knitted from medium-thick threads. The lower part of the hat, on the other hand, is characterized by a two-layer, thicker knit that has been carefully sewn and folded over . This special finish gives the hat not only an extra layer, but also an attractive look and a high level of comfort.
As a color contrast to the blue base color, the hat has a patch showing the manufacturer’s name Nebulus and the Norwegian flag. This patch creates an interesting visual effect.
The fabric of the hat is thick, slightly stretchy and tear-resistant. According to the manufacturer, the hat is made of acrylic. The seams are all evenly and neatly finished. There are hardly any protruding threads and, if there are any at all, they are only very short. Apart from this, no other manufacturing faults can be found on the hat.
Overall, the blue RULES hat from Nebulus is a fashionable accessory. The quality of the materials used and the neat workmanship of the seams are impressive.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

The one-size-fits-all design of the RULES cap allows customers with different head sizes to wear it. Furthermore, as a unisex product, the cap is equally suitable for all genders. This is undoubtedly an advantage, as there is no need to select a specific size. However, our male tester noted that the cap was a little too tight and therefore felt slightly uncomfortable. However, it is important to note that this can be subjective and depends on individual preferences and head shapes. We would still wish for a second size. The fit is good for women with an average head size.
The material feels comfortable on the head. The thick knitted fabric keeps the hat very warm. It also protects the ears well. The RULES hat is therefore also suitable for particularly cold winter days.
Another aspect that should be taken into account when caring for the hat is the fact that it can only be washed by hand . This means that customers have to spend extra time and effort to keep the hat clean. It is advisable to follow the manufacturer’s washing instructions to ensure the quality and longevity of the cap. In our opinion, however, a material that can withstand machine washing would be a great advantage in terms of handling.
Overall, the RULES beanie impressed us in our practical test. It fits our tester comfortably, feels pleasant against the skin, keeps her nice and warm and also withstands washing without any problems.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also examine consumer ratings and check whether the critical and positive reviews are actually justified.
