HASTER UltraClima underwear is made in seamless technology with the participation of polypropylene microfiber. Ultraclima is the most refined and technologically advanced collection of seamless underwear. The unique composition of UltraClima causes that the underwear:

- breathes thanks to the optimal fiber structure
- suitable for use with intense effort
- it removes moisture well thanks to the developed capillary system of polypropylene fibers and at the same time retains warm air,
- comfortably adheres to the skin thanks to the use of flat seams,
- transports sweat to the outside, drying the skin.
- gives optimal wearing comfort, does not cause irritation and is pressure-free,
- provides adequate ventilation through a special system of knitted textures (adapted to the anatomy of the figure) - shows above-average drying capacity.
-has antibacterial functions, neutralizing negative odors

UltraClima thermoactive underwear is significantly drier during / after exercise than other types of underwear - because polypropylene microfibre is hydrophobic - it does not absorb moisture.
In order for thermoactive underwear to function properly, it should fit the body perfectly. Appropriate selection of the size ensures adherence to the skin surface, thanks to which a proper microclimate is obtained.
