FAQ - Frequently Asked Questions

The mechanical stretch properties of Trustgarn products guarantee optimal adaptation to the shape of the body, which not only increases comfort but also allows for double sizes. This makes handling and selecting clothing much easier. We recommend choosing a size smaller. For example, if you are a size M, it is advisable to buy the item in S/M. If you are a size L, you should buy M/L.

The right clothing is very important for people with neurodermatitis, psoriasis and diabetes. It influences physical and psychological well-being. By choosing suitable materials and cuts, those affected can significantly improve their quality of life. Everyone, regardless of their health challenges, should have the right to dress themselves and with confidence.

An international expert commission of dermatologists in atopic dermatitis research recorded both the importance and requirements for optimized atopic dermatitis clothing in consensus papers (guidelines) as early as 1999. This shows that mechanical irritation factors (e.g. rough, scratchy fiber ends) and chemical irritation factors should be avoided: fiber material, yarn, surface, finishing and cut design as well as the sliding behavior of the underwear on the skin - and under conventional outer clothing - are important parameters in the development of optimized clothing systems for diseased skin.

For this reason, textiles worn close to the body must be selected very carefully by those affected.
Recommendations for buying suitable clothing for people with neurodermatitis can be found primarily on the Internet, many of which are scientifically dubious. Such recommendations are usually based on experience and not on scientifically sound results. For example, natural fibers are recommended, i.e. pure cotton - preferably "organic" - silk, linen and hemp. Wool and new wool are not recommended due to the roughness of the fibers.

We exclusively use the existing knowledge of HAMED, the pioneer in research into textiles with direct skin contact. The fibers of the FG02/60Z series, further developed by HAMED and tailored to the manufacturing process, are antibacterial, suitable for allergy sufferers, do not produce microplastic abrasion and are the basis for previously unknown usage properties and unique wearing comfort.

The basic material of our textiles is not a new invention and is used in a modified form in medical technology. Stents, heart valves, surgical sutures and burn compresses are made from the basic material.

Trustgarn's three-dimensional manufacturing process is an exclusive and central element that distinguishes our products. This process makes it possible to make the garments significantly lighter without sacrificing quality and functionality. The items gently adapt to the body and are particularly beneficial for people with sensitive skin that is sensitive to pressure and friction.

We are setting new standards with our developments in the field of clothing for patients with dermatoses such as neurodermatitis, psoriasis and diabetes. Through close cooperation with our partners as part of a European research project, we have redesigned the manufacturing and process chain. The challenge in producing clothing for people with skin diseases is to enable direct contact with the diseased skin without causing additional irritation or discomfort.

The uniqueness of our underwear lies in its complex and three-dimensional honeycomb structure, which is both patented and unparalleled in the industry. This special structure not only offers an optimal fit, but also enables effective regulation of body temperature.

Targeted air circulation creates a pleasant microclimate, which is particularly beneficial for patients with dermatoses.

The redesigned manufacturing system, together with the unique three-dimensional knitting process, enables us to offer products that meet the specific needs of this patient group.

Trustgarn underwear sets new standards in terms of comfort and skin compatibility. A key feature is the low coefficient of friction, which, in combination with an almost identical value for adhesive and sliding friction, enables a seamless transition between standing still and moving. This non-stick effect is particularly beneficial for people with diseased or sensitive skin.

Exceptional comfort is the result of the unique manufacturing system. The underwear is manufactured using a patented knitting system that is not only breathable, but also has thermoregulating properties. This has a significant positive effect on individual comfort and represents a striking distinguishing feature from competitors.

Another advantage of our products is that they have no negative impact on the physiological skin flora. They are biocompatible and do not contain microplastic abrasion. This not only contributes to skin health, but also to the sustainability and environmental compatibility of our textiles.

Trustgarn products are the result of extensive tests carried out at the renowned Hohenstein Institutes. These tests for mechanical skin irritation and biocompatibility, in accordance with DIN EN 10993 23, are proof of the high quality and safety of the textiles. Recognition as medical devices and approval in the European medical device database EUDAMED underline Trustgarn's seriousness and commitment to developing products that are both effective and safe.

The tests carried out revealed the following properties and characteristics:

Medical product • Medically tested • Suitable for people with atypical dermatoses such as neurodermatitis and psoriasis • Breathable • Biocompatible • Thermoregulating • Allergy-friendly • Skin-friendly and tested as a “skin care” product • Free from harmful substances • Non-irritating • Antibacterial • Biocompatible and tested for harmful substances

The following were also excluded during the examination series:

Cell damage • Allergy-causing effects • Negative skin reactions

The Hohenstein Institute is a renowned research and service facility originally based in Bönnigheim. Textiles such as bedding and clothing are tested there. In addition, research is carried out in other laboratories in Europe, Asia and the USA. Textiles and chemical substances are tested as part of the research at the Hohenstein Institute. In addition to clothing, bedding and toys, detergents and washing equipment are also tested. The fit of clothing and the quality are also examined as part of the tests.

Our articles meet the requirements of the directives as a Class I medical device (Regulation (EU) 2017/745 MDR, Annex VIII, Rule I) and are compliant with Regulation (EU) 2017/745 MDR, Art. 19, Annex II + III

Our articles have been medically tested, tested for skin irritation and examined for harmful substances. Our products also have a significant antibacterial effect. These and other tests form the requirements to achieve conformity as a Class 1 medical device with the lowest risk for patients.

Our products are manufactured with dedication and the utmost precision to ensure maximum quality and sustainability. To ensure that this excellent quality and durability is maintained, please pay attention to the following information.

✓ Do not use fabric softener

✓ Use a mild liquid detergent

✓ Use a laundry bag for washing machines

✓ Wash the shirts at 30° on a wool or delicate cycle

Adjustment and size recommendations for textiles from Trustgarn (detailed explanation)

Choosing the right clothing size is crucial for comfort. The mechanical stretch properties play a key role, especially in Trustgarn textiles. These special properties not only ensure optimal adaptation to the body shape, but also offer the possibility of using double sizes.

The stretching mechanism in Trustgarn textiles (as described above) allows the fabrics to adapt flexibly to the individual body shape. This results in a comfortable wearing experience. Another
The advantage of these stretch properties is the ability to offer double sizes, which is a welcome flexibility for many customers.

To ensure the best possible fit, it is recommended to choose a size smaller. This recommendation is based on the specific properties of the materials, which adapt to the body over time while still retaining their shape. For example, customers who usually wear a size M should purchase the items in the size combination S/M. This choice ensures that the garments fit snugly without being uncomfortable.

For customers with a clothing size L, it is advisable to choose size M/L. This decision not only supports the handling and selection of clothing, but also ensures that the garments fit perfectly and that the advantages of the stretch properties are fully exploited. The stretch properties of Trustgarn textiles ensure excellent adaptation to the shape of the body and allow for a significant increase in wearing comfort.
