Many shell jackets have very thin mesh liners. 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. A staff member who usually wears size XL, commented this jacket: "Normally I choose XL, but with this jacket XL felt a bit loose, while L was clearly too small." *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 - Hem adjustment - Three zipper pockets This is a PFC-free product.
