Lightweight Insulated Jackets

Which insulation do you prefer?

• Down: Ultralight, warm and packable—but won't insulate when damp and dries slowly.
• Synthetic: Insulates when damp, dries fast and often less pricey than down—though heavier and less packable.
• Wet or humid conditions or high activity? Consider water-resistant down, synthetics or down/synthetic hybrids.

How much will temperature and weather vary?

• Most insulated jackets feature water-resistant shells. Some use waterproof/breathable material—pricier but they eliminate the need for a separate rain shell.

• For high-exertion activities, look for vents in the underarm or core area to dump heat.
• Some jackets vary insulation and shell materials based by body zone to provide weather protection and breathability where needed.

Consider features:

• Hoods: Add warmth and protection; some are detachable or helmet-compatible
• 3-in-1 jackets: Combine an outer shell and midlayer that zip together, so you can wear separately or as one
• Pockets: Designed to stash gear, secure valuables and more.
