Nebulus
Polo shirt SINES

The Summerfresh polo shirt from SINES made a very good overall impression in our test. The polo shirt has three buttons on the front and various decorative elements in orange. It is available in six different colors and sizes. For our test, we received the polo shirt in dark blue and size M. The polo shirt fits our tester like a glove. The material quality and workmanship were just as impressive as the polo shirt in the practical test. This shows that the polo shirt fits comfortably for a long time and ensures good ventilation even at high temperatures despite its sporty cut. You can also add your own personal style by opening or closing the typical polo shirt buttons on the front.

Advantages

✅ High wearing comfort
✅ Good workmanship and quality
✅ Buttons on the front
✅ Shape-retaining collar
✅ Various decorative elements

❌ A few protruding threads

Packaging and labeling

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be ensured.

The polo shirt in its product packaging

In our case, the Summerfresh polo shirt from SINES was delivered together with other products in a sturdy shipping box . The shipping box was undamaged and could be easily opened with a knife or scissors. The shipping box was also optimally sized, as it was filled to the top. This protects the environment: not only is the amount of material required for the shipping box minimized, but the small space required by the package also ensures better utilization of the transport vehicles. Inside the box was the SINES polo shirt in its product packaging.
The product packaging consists of a transparent plastic bag in which the SINES polo shirt was packed. The film is tear-resistant and cannot be stretched. A Summerfresh logo is printed on the front of the packaging. There is also a sticker with a barcode and the product name and size of the polo shirt. 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 on the film. The adhesive strip is reusable. If the shirt is sent back, the bag can be resealed with the existing adhesive strip.
The SINES polo shirt is very well protected from damage and soiling by the shipping box and the plastic bag.

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?

As you would expect, the SINES polo shirt does not require any additional accessories and is delivered without them. There is a playing card-sized box on the label, which is printed in high gloss with the Summerfresh logo depicting a pineapple.
There are no instructions for use, but they are not needed. Washing instructions can be found on a label on the inside of the shirt, where this is illustrated with the familiar symbols. There is also information on the material composition of the SINES polo shirt and the size and product name.

Back of the polo shirt

For our test, we received the Summerfresh polo shirt from SINES for men in dark blue. In addition to this color, Nebulus also offers the polo shirt in grey, green, light blue, orange and white. The dark shade of blue is subtle and can be worn for any occasion. The polo shirt is evenly woven from fine threads and feels pleasant both inside and out.
As is usual with polo shirts, the polo shirt has an opening at the front that reaches down to the chest. This overlaps on a strip around three centimetres wide, on which three buttons are positioned one above the other. The buttons have a matt, shimmering orange color. The orange color serves as a contrast to the dark blue of the rest of the polo shirt and is also used in several other places. The polo shirt does not have a breast pocket.
Unlike the majority of the polo shirt, the collar is sewn from thicker threads and therefore has a different structure to the rest of the shirt. As a result, the collar is also thicker than the rest of the fabric, making it particularly dimensionally stable. The color is largely identical to the rest of the polo shirt, but there is a narrow orange stripe at the bottom that matches the buttons. This design is also picked up on the sleeves. A section around two centimetres wide is sewn onto these, which is also sewn with thicker thread and therefore of a different thickness and strength. Like the collar, this also ends with an orange stripe running all the way around.
The orange color can also be found in other special design elements. These include the Summerfresh logo with the brand-typical pineapple, which is printed on the left chest. As a special extra, the back fabric layer of the overlapping area around the chest opening is also orange.
The fabric of the polo shirt is stretchy and tear-resistant within limits. Although it is not particularly thick and therefore pleasantly light , it is completely opaque. According to the label, the shirt is made entirely of cotton. The seams are all even and neatly finished. Unfortunately, there are a few protruding threads, but these are only very short. Apart from this, the polo shirt has no manufacturing faults. The polo shirt has the typical, pleasant smell of brand-new clothing.
Overall, the polo shirt in dark blue with orange decorative elements has a summery and appealing design. The quality of the fabrics used and the seams, as well as the overall finish, are also 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 maximum score is 100 points

The Summerfresh polo shirt from SINES is sold in various sizes between S and 3XL. In our test, we received the polo shirt in M. The polo shirt fits our slim tester, who is 170 cm tall, like a glove. The shirt fits comfortably and is loose-fitting, making it very comfortable. The fabric feels pleasant against the skin, as you would expect from a polo shirt. Another positive aspect is that there are no irritating labels on the inside that could cause scratching when worn. The existing label has soft edges and is not noticeable.
The polo shirt can be personalized using the three buttons. When the buttons are opened, the orange fabric behind the overlap is also visible. If the top button is closed, none of this is visible. The neckline of the polo shirt is then tight, but without unpleasantly constricting the neck.
The low weight of the polo shirt is noticeable when worn. The shirt is therefore not uncomfortable to wear, even during sporting activities. The fabric is also slightly permeable to air, making it comfortable to wear even at high temperatures. In this context, the cut of the polo shirt is particularly impressive. Although the T-shirt is figure-hugging, it does not sit directly against the body. This leaves a thin layer of air between the fabric and the body, which ensures good heat dissipation in high temperatures or during physical exertion.
In the last part of our practical test, we wash the polo shirt according to the manufacturer’s instructions. In the case of the Summerfresh polo shirt from SINES, this means an easy-care wash cycle at 30 °C without drying and ironing at 110 °C, which corresponds to the usual specifications for comparable garments. After washing, the laundry smells of the detergent used, but otherwise there is no noticeable difference. Both the polo shirt and the print survive the washing process without any damage or fading.
All in all, the Summerfresh polo shirt from SINES impressed us in our practical test. It fits comfortably, can be used flexibly, has an advantageous cut 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.

*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.2 stars. Many customers criticize that the green color does not look like the one in the pictures, but is much darker. As we are not testing the polo shirt in green, but in dark blue, we are unable to judge this. The dark blue matches the color in the sales pictures. Many customers praise the good quality, the packaging and the advantageous cut of the polo shirt. We were able to confirm this in our practical test.

Prices of up to €79.90 are charged on the Internet for equivalent products. Very inexpensive products are available for as little as €8.92. The Summerfresh polo shirt from SINES is currently in the lower price segment with a price of €19.99 on Amazon. The price ratio is very good for the quality and scope of services you get.
