The KOS 80 Flex Jacket Mens by Killtec is a lightweight stretch fleece vest designed for outdoor activities and everyday layering. With its full-length zipper and regular fit, it offers warmth and comfort when you need a reliable mid-layer on cool days or a standalone piece during mild weather.
Constructed from a blend of 95% polyester and 5% elastane, this jacket features Killtec’s Power Stretch technology, giving it a four-way stretch that moves with your body. The material combination ensures quick-drying performance and retains its shape, while the regular cut allows room for base layers without feeling bulky—ideal for hiking, travel or relaxed weekend wear.
Power Stretch refers to fabrics engineered to combine polyester’s moisture-wicking and durability with elastane’s elasticity. Elastane is a synthetic fiber known for its ability to stretch and recover, so the jacket adapts to your movements and maintains its fit over time. This means less restriction on the trail and consistent comfort throughout your activities.
