Sonic Hoody – Men's

For high-output cold-weather efforts where bulk kills performance, the Sonic Hoody is our go-to midlayer for trail runners and fast-and-light alpinists. Graphene-enhanced fabric pushes thermal efficiency well past standard fleece, so you stay warm without overheating when the pace picks up. The low-profile fitted hood layers cleanly under a helmet or hat without shifting.

• Graphene-enhanced fabric delivers more warmth per gram than standard fleece — serious heat retention without the weight penalty
• Stretchy athletic construction moves with you through full range of motion, whether you're grinding uphill or pulling on a shell
• Fitted hood sits low-profile under a helmet or hat — stays put without bunching or riding up
• Built for high-output cold-weather activity: trail running, fast hiking, and alpine approaches where regulating body temp matters
• Graphene colorway is a versatile dark neutral that disappears cleanly under any outer layer
