Outdoor vests add core warmth or storage while keeping the arms free. Fleece vests breathe well during movement, while insulated vests provide more warmth for their weight and are useful in cool, dry conditions.

Compare insulation or fleece weight, breathability, wind resistance, weather resistance, packability and pocket placement. Choose fleece for active moisture management and insulated construction when warmth-to-weight matters more.

Keeping the core warm can improve comfort without trapping as much heat around the arms. A vest does not replace a shell in strong wind or rain, but it can be an efficient part of a layering system in cool, variable weather.
