Insulated Jackets

Insulated jackets are outerwear designed to keep you warm by trapping body heat. Unlike waterproof jackets that protect you mainly from rain, insulated jackets focus on thermal insulation — they help retain your body heat in cold conditions.

Main Purpose:

To keep you warm in cold weather by using materials that trap heat.

Types of Insulation:

1. Down Insulation (Natural):

   • Made from duck or goose feathers (the fluffy undercoating).

   • Pros: Super warm, lightweight, compressible.

   • Cons: Loses warmth when wet (unless treated); can be expensive.

2. Synthetic Insulation:

   • Made from man-made fibers (e.g., PrimaLoft, Thinsulate).

   • Pros: Retains warmth even when wet, cheaper, hypoallergenic.

   • Cons: Slightly heavier and less compressible than down.

Key Features:

• Insulated Layer: Traps warm air close to your body.

• Outer Shell: Sometimes water-resistant or waterproof.

• Lightweight to Heavyweight Options: Depending on temperature needs.

• Packability: Some compress into small sizes for travel.

• Hooded or Non-hooded: Hood adds extra warmth.

Common Uses:

• Winter hiking, skiing, snowboarding

• Everyday winter wear

• Mountaineering or alpine climbing

• Layering under a shell in extreme cold

Comparison: Waterproof vs. Insulated Jackets

Note: Some jackets combine both features — waterproof and insulated — especially in winter or ski jackets.
