Klim Aggressor -1.0 Long Sleeve

The KLIM Aggressor -1.0 Long Sleeve is built for riders who generate plenty of heat and need a base layer that helps them stay cool rather than warm up. Designed as the lightest and coolest option in KLIM's Aggressor layering system, the Aggressor -1.0 uses advanced chemical-free cooling technology to actively improve comfort in warm riding conditions. The lightweight mesh construction promotes airflow while rapidly moving moisture away from the skin to enhance evaporative cooling. Unlike traditional treatments that can lose effectiveness over time, the cooling properties are built directly into the fabric for consistent long-term performance. With fast-drying materials, antimicrobial properties, and 4-way stretch comfort, the Aggressor -1.0 Long Sleeve is an ideal choice for spring riding, mountain riding, adventure touring, motocross, and high-output snowmobile riding. It's basically designed for riders who are more worried about overheating than staying warm.
