How warm is it compared with a regular fleece?

It is a midweight fleece, warmer than a thin grid fleece and about on par with a standard 200-weight pullover. It works as an outer layer in cool, dry weather and as a midlayer under a shell in cold.

Does it fit true to size?

Most buyers take their usual size, but the cut is trim through the shoulders and chest. Those who want room for a base layer underneath often size up.

Is it windproof or waterproof?

No. The fleece blocks some chill but wind passes through, and it is not water resistant. Wear a shell over it in wind or rain.

How should I wash it?

Machine wash cold with like colors and tumble dry low. Avoid fabric softener, which coats the fleece, and wash it with other synthetics to limit lint pickup.

Is it good for hiking?

For mild, low-output days, yes. For steep climbs it can run warm, so many hikers use it as a layer they put on at rest stops rather than wear the whole way.

What makes it different from Patagonia's other fleeces?

The sweater-knit face gives it a casual, non-technical look, while the R1 and similar pieces are built for breathability during activity. The Better Sweater favors warmth and everyday wear.
