A fleece vest warms the core while leaving the arms free, making it useful for active hiking, travel and transitional weather. It is a smart option when a full fleece jacket feels too warm but a T-shirt or baselayer is not enough.

Compare fleece weight, breathability, wind resistance, pocket placement and bulk. Lightweight vests work well under a shell, while thicker fleece can serve as a casual outer layer in dry conditions.

Core warmth can make the whole body feel more comfortable without trapping as much heat around the arms. However, a vest provides limited wind and weather protection, so combine it with an appropriate shell when conditions become exposed.
