Heatseeker Insulated Jackets

Which insulation do you prefer?

• Down: Ultralight, warm and packable; loses insulation when damp
• Synthetic: Insulates when damp, dries quickly; heavier and less packable than down
• Down/synthetic: Warm in targeted spots; warm when wet but heavier than pure down

Consider these features

• Waterproof: Most are water-resistant; choose waterproof for added protection

• Ventilation: Pit zips or core vents help release heat during high-exertion activities
• Hoods: Some detach or accommodate helmets
• 3-in-1 jackets: Outer shell and insulated midlayer zip together; wear separately or as one
• Pockets: Stash gear, secure valuables
