The Biegga Neve boasts a brushed tricot liner, making it both comfortabl even with short sleeve tops, and slightly warmer than average, perfect for use in cool and cold weather. This jacket will serve you both on hikes and everyday outdoor use. *Note!* The liner fabric is far from being thick, but it's more comfortable when combined with a short sleeve top, and a bit warmer. - Waterproof, windproof, breathable DrymaxX Ultimate main material - Liner: brushed Active Dry tricot - Integrated, adjustable hood - Cuffs with Velcro adjustments - Pit ventilation - Three zipper pockets - Hem adjustment This is a PFC-free product.
