Killtec KOS 91 Flex Jacket 70512255

The Killtec KOS 91 Flex Jacket is a knitted fleece vest designed for men who spend time outdoors and need a reliable mid-layer. Its straightforward construction makes it a go-to piece when you want extra warmth without bulk, whether you’re hiking, camping or simply layering up for a chilly morning.

Made entirely from 100% polyester, this vest combines a full-length zip with a regular fit to balance freedom of movement and insulation. The knitted fleece surface traps heat close to your body, while the zip lets you quickly adjust ventilation as conditions change. It’s a simple design that slides under a shell or stands alone on crisp days.

Polyester is known for wicking moisture away from your skin and drying quickly, so you stay comfortable even if you work up a sweat. The regular fit means the vest sits close enough for efficient layering but leaves enough room to move freely.
