About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

LightDry®
Mummy sleeping bag

The LightDry® mummy sleeping bag is the ideal companion for camping, bike tours and other excursions from spring to fall. With its low weight, small pack size and water-repellent outer shell, it offers ultimate comfort and protection from the wet. The mummy cut and the additional warm collar ensure comfort and warmth. During the test, positive features such as the practical MHI hollow fiber filling and the versatility of use were noted. However, some customers complained that the sleeping bag did not insulate sufficiently and that condensation remained inside.

Advantages

✅ High-quality materials
✅ Versatile use for 3 seasons
✅ Lightweight and compact
✅ Water-repellent

Disadvantages

❌ Use of plastic packaging

The first impression

Packaging and contents

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 guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

Weighting: 20%
*The maximum score is 100 points

The LightDry® mummy sleeping bag iscarefully packed and delivered without unnecessary packaging material. The packaging is adapted to the size of the product and offers sufficient protection. The product itself is undamaged and shows no scratches or soiling. Unfortunately, the packaging is made of plastic, which is not very sustainable. The scope of delivery includes the sleeping bag and a carrying bag. Instructions for use were not included, but the sleeping bag is intuitive to use.

Product processing and appearance

ℹ️ Before we start the practical test, we take a close look at the workmanship of the products. How high quality are the materials used? Are the look and feel satisfactory?

Tasche des Mumien-Schlafsacks
Pocket of the mummy sleeping bag

The LightDry® mummy sleeping bag is visually very appealing. The workmanship is very good, there are no scratches. The sleeping bag is very stable and the material is hard-wearing. Unfortunately, there is no information on the durability of the product, but we expect it to last a long time. The sleeping bag was slightly deformed at first, but this normalized after a short time.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test has the highest relevance and therefore weighting. 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 sleeping bag was found to be very comfortable, with sufficient legroom and the option of sleeping on your side. The design was praised as appealing and suitable for camping. The lightweight material is well suited for the summer months. The sleeping bag is easy to pack and has a standard closure.
Even colder nights could be survived well with the sleeping bag.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we examine 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?

CriterionRemarkScore achieved*
Price / performance ratioVery good price-performance ratio90 points
Rating cut4.0 out of 5.0 stars on Amazon50 points
Total70 points
Weighting: 15%
*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.0 stars. The high level of impermeability, the good price-performance ratio and the reasonable price are highlighted as positive aspects. One criticism is that the sleeping bag does not keep you warm enough on cold summer nights and condensation remains inside.

Prices of up to €130 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €24 . The LightDry® mummy sleeping bag is therefore currently in the lower price segment with a price of €39.99. For the quality and performance received, the price-performance ratio is very good.
