The durable 2-layer material is combined with SEAL synthetic insulation and has a hydrophobic surface treatment that protects against moisture. The materials used regulate heat very well and wick away moisture quickly. Thanks to the sporty cut, the jacket offers a large range of movement. To prevent snow from penetrating inside, we used an elastic snow belt with snap closure and added an adjustable bottom edge to the jacket. But also adjustable Velcro cuffs with inner elastic sleeves with thumb hole for the best possible jacket fixation. Strategically placed mesh vents in the armpits provide additional ventilation.
