Spyder Men's Bolt Shell Jacket:
Technical shells should stand up to external weather conditions and allow airflow to prevent internal condensation and overheating. The Bolt has a upper back exhaust vent to allow venting in a typical hot spot. Underarm zippered vents put you further in control of your microclimate. Layer underneath for cold weather, or simply wear a baselayer in warmer temperatures. The Bolt has you covered.
