UYN Natyon 3.0 Poland Pants Medium 2026 UnderwearUYN Natyon 3.0 Poland Pants Medium 2026 Underwear is the highest, representative class of thermal underwear—a model tested in competition conditions and recommended by the world's top national teams.The latest generation is as much as 34% lighter than its predecessor thanks to a redesigned construction and the full integration of bio-NATEX fiber, while also being 4% more flexible, providing exceptional freedom of movement while maintaining full stability.A combination of sports laboratory research and on-slope testing allowed the introduction of new functional zones: Meta-Ribs on the quadriceps, which stabilize and support muscles under load, and Pressure Branches on the knees—relieving joints, improving ligament function, and reducing Point-specific pressure during intense activity. Targeted compression increases blood flow to the limbs, reduces fatigue, and improves movement dynamics.This model has a strictly athletic character, designed for the most demanding users who expect underwear at the level of the national team.Features of the UYN Natyon 3.0 Poland Pants Medium 2026NATEX – a new generation natural fiber Bio-yarn made from 100% natural raw materials, exceptionally lightweight and quick-drying. It reduces clothing weight by as much as 34% and dries 50% faster than traditional fibers. Its elasticity allows for a precise fit, and its natural bacteriostatic properties reduce odor during prolonged activity.HEATMEMORY – active heat retention Special insulating chambers retain heat in key muscle zones, preventing cooling after stopping or when intensity drops. The system works both during training and in competition, ensuring a constant microclimate.META-RIBS – stabilizing muscle micro-network An advanced rib structure woven directly into the quadriceps area. It creates gentle pressure that stabilizes muscle function, supports correct posture, and improves concentration. It also improves blood flow, allowing muscles to work at their optimal level for longer.PRESSURE BRANCHES – knee joint relief Special pressure relief channels reduce pressure on ligaments and areas most vulnerable to overload. They improve comfort, smooth movement, and minimize micro-strain, which is crucial during dynamic position changes.Targeted compression – improved blood flow Stronger compression on the limbs increases circulation, reduces the effect of heavy legs, and slows the onset of fatigue. Ideal for intense training, skiing, running, and activities in cold conditions.Ultra-lightweight race-ready construction – 34% less weight Minimalist weave and reduced layers make the pants noticeably lighter while maintaining full joint and muscle stabilization. This is performance-class clothing inspired by national team clothing.Frequently Asked QuestionsFor whom?
