Helikon-Tex Chinook Waterproof Jacket

Helikon-Tex Chinook waterproof jacket with 2.5L membrane (20,000mm / 20,000 g/m²/24h). Lightweight (400g), with taped seams, ventilation zippers & YKK® zippers

The Helikon-Tex Chinook Rainproof Jacket (Code: KU-KCH-PO) is an extremely lightweight (weighing just 400 gr in size L) and durable outer garment, designed to provide complete protection from rain, snow, and wind in temperatures ranging from -5°C to 10°C. It is part of the Patrol, Outback, Range & Urban lines, offering an ideal solution for operational use, shooting range, hiking, and everyday urban commuting.

Equipped with an advanced 2.5L membrane (100% Polyurethane), it achieves top-level waterproofing of 20,000 mm and excellent breathability of 20,000 g/m²/24h. This combination prevents water from penetrating from the outside while effectively releasing moisture and body heat during intense physical activity. The outer fabric (100% Polyester, 100 g/m² density) features a PFC-free DWR (Durable Water Repellent) coating, preventing the absorption of water and dirt.

For complete waterproof protection, the Chinook features taped seams, two-way waterproof YKK® zippers, and a Prym snap fastener at the bottom. The 2-point adjustable hood with a high collar protects the face, while the underarm ventilation zippers allow immediate temperature regulation. It includes 4 functional pockets (2 front pockets with protective flaps and 2 zippered shoulder pockets), Velcro panels on the shoulders for attaching patches, as well as adjustable Velcro cuffs and a drawcord at the hem.

Thanks to its compact design, the jacket can be stored inside its own hood or in the included carrying bag, taking up minimal space in a backpack.
