The outer fabric is elastic (95% polyester, 5% elastane) and features an integrated membrane that makes it windproof and water-repellent. The surface is additionally treated with Bionic Finish® Eco for enhanced water repellency, without the use of fluorocarbons (PFC-free). The interior of the jacket has a soft brushed fleece lining to provide warmth.
The design includes four pockets (two on the chest, two for the hands) with zipper closures, adjustable cuffs with Velcro, elastic inner cuffs for better insulation, and an adjustable drawcord at the bottom. It is worth noting that the product does not have taped seams.
