Outerwear & Layers

Windbreakers, half-zips, and warm-up layers for training outdoors.

Packable Windbreaker

Stuffs into its own pocket for a run-commute bag; windbreakers trade warmth for packability, so pair with a base layer below freezing.

Waterproof Rain Shell

Check the listed waterproof rating (mm) against 'water-resistant,' which is a different, lower bar — the two get used interchangeably in titles.

Warm-up layer for before and after training, not built for running in — the fleece lining adds bulk and traps heat.

Common Questions

Before you buy outerwear & layers

What's the real difference between water-resistant and waterproof?

Water-resistant sheds light rain and repels it for a while before soaking through; waterproof (usually rated in millimeters on the listing) holds up under sustained rain. The two terms get used loosely in titles, so check the product description specifically.

Do I need a vest and a jacket, or just one?

They solve different problems — a vest adds core warmth without sleeve bulk for mid-range temperatures, a jacket adds full coverage for cold or wind. Runners who train across seasons often end up with both rather than one do-everything piece.

How much warmer does fleece lining actually make a jacket?

Meaningfully, but it also traps more heat and adds bulk — fine for pre/post-workout warmth, less ideal for the run itself where you'll generate your own heat quickly. Check whether a listing is marketed as a warm-up piece or an actual running shell.
