Thermounterwäsche UYN Man Elevatyon Biomorph UW Pants Medium Black - 2025/26

The UYN Man Elevatyon Biomorph underpants are made from bio-derived fibers and designed to improve leg function in cold temperatures. Biomorphic construction provides a natural range of motion, while sophisticated three-dimensional technology supports muscles and improves natural thermoregulation.

Joint-protecting structure: Like the connective tissue of cartilage that protects joints from shock and promotes movement at the same time, Proconnect technology provides greater strength in the most exposed areas without affecting the elastic characteristics of the fabric

Fabric breathes in areas of high perspiration: In areas where perspiration is particularly intense, Biodry technology expels sweat through fine bio-fibres and allows the skin to breathe. The three-dimensional structure is developed by studying skin respiration in amphibians. In these cold-blooded animals, the skin is thin, highly vascularised and has numerous folds to increase surface area

Retains heat and turns it into energy: Isoduct technology targets those areas of the body that tend to cool quickly. Channels integrated in the fabric retain air in contact with the skin, so it warms up through body heat and creates a protective layer to the outside. The principle of Isoduct technology is inspired by the fur of arctic animals. The hairs create pockets that trap air, which is the most powerful insulator in nature, and protect against the cold.

Alveolar structure for active breathability: The thinner structure of the knitted fabric mimics the functions of the pulmonary alveoli by facilitating the exchange of moisture produced by the body with fresh air outside for superior breathability management. The alveoli are the smallest structures in the lungs, their function being the exchange of respiratory gases between the blood and the atmosphere. They look like small air chambers with a very thin wall.

Support and flexibility from wing veins: Inspired by the veins of insect wings, this ultra-light and flexible 'exoskeleton' provides targeted support in all areas of the body that need it, while at the same time connecting the functional zones. Insect wings are extremely powerful in relation to their weight. The intricate pattern of veins defines their functionality and distinguishes insect types from each other.

Quick to dry, quick to make you feel comfortable: ariacel was born from the cellulose filaments of wood pulp. it innovatively combines the comfort of natural fibers and the functionality of synthetic fibers cool to the touch thanks to its structure, ariacel fiber dries quickly, leaving the skin feeling cool

bright and flowing: because of its appearance, this fiber is similar to silk

Beech fibre, durable and breathable: BIOLIGHT is a plant-based fibre that gives UYN garments unique characteristics. Derived from the cellulose of beech plants, this fibre is smooth, soft and bright, and provides and extremely pleasant touch. BIOLIGHT is characterised by its breathable properties and its ability to retain moisture (twice as much as cotton). Thanks to its structure, BIOLIGHT fabric helps to keep the skin cool and dry. BOTANIC ORIGIN Extracted from the beech tree from responsibly managed forests 100% BIODEGRADABLE Born from nature, returns to nature SUPERIOR PERFORMANCE Retains twice as much moisture as cotton, is pleasantly soft and light.

The vegetable wool: Nature never fails to amaze us. Nature gives us KAPOK, a precious and totally organic fibre obtained from the fruit of the Ceiba Pentandra, a sacred plant that grows up to 60 metres high, widespread in the rainforests of South America. Known as 'vegetable wool' for its extraordinary lightness, KAPOK fibre has only recently been used in the textile industry for padding cushions and mattresses. We at UYN were the first to succeed in using the natural yarn in sportswear - as a fabric with exceptional active properties and not as padding. THE WORLD' S LIGHTEST NATURAL FIBRE KAPOK is a hollow fibre composed of 80% air, with a very low density (0.35 g/cm3). Because of this, Kapok is the lightest natural fibre in the world. NATURALLY INSULATING The structure allows the KAPOK fibre to trap a large amount of body-warmed air thus creating an insulating barrier that protects against temperature changes. SOFT AND HYPOALLERGENIC High-quality and soft, it dries quickly, is hygroscopic and has natural antibacterial and hypoallergenic properties. TOTALLY ORGANIC KAPOK fibre grows wild in pristine forests, no intensive cultivation is required and the fiber is harvested by hand. No fertilizers or pesticides are used in its cultivation.

Eucalyptus wood has never been so comfortable: The wood obtained from Eucalyptus trees becomes ECOLYPT, a 100% sustainable natural fiber with exceptional properties. The characteristics of the pulp of the wood from which it is obtained give ECOLYPT strength and great elasticity. Its structure is composed of very small hydrophilic fibers that absorb up to 50% more moisture than cotton. In addition, the fiber is highly breathable, minimizes the formation of odors and thanks to its temperature regulating properties is able to provide a cooling effect in hot temperatures and warm in cold days. The entire production process of ECOLYPT fiber is characterized by a closed loop: all water and enzymes are recovered and reused in a further production process.
