Is this warm enough for winter hiking?

Yes as a base layer under a mid layer and shell. On its own it is not enough for severe cold or wet weather.

How does it compare with merino base layers?

It is thinner and cheaper-feeling than merino and wicks well, but merino offers more warmth and odor resistance.

It is designed as a close-fitting base layer with stretch. Some buyers say it runs small, so consider sizing up if you are between sizes.

It can be worn alone for mild activity, but it is built as a layer and offers little protection from wind or rain.

Yes. The zip lets you vent heat quickly during climbs or hard effort without removing layers.

It is a synthetic thermal top and is typically machine washable on a cool cycle. Follow the care label.
