Warmer than a lightweight crew but far from a bulky sweater, the Patagonia Capilene Thermal Weight Women's Zip Neck lands in the sweet spot for winter baselayers. The gridded fleece face feels soft and holds heat, and the neck zipper gives you quick control when the effort ramps up.

Why we like it:

The real selling point is versatility, since it works solo on the skin track and layers invisibly under a shell when the temperature falls.

Features and Functions:

This grid fleece is Polartec Power Grid, 4.5 ounce of recycled polyester with a touch of spandex, using its raised grid to trap warmth and its open channels to move moisture, and HeiQ Mint fights odor over long trips. A tall zip-neck collar shields the throat, flat seams keep the top smooth under layers, and it is Fair Trade Certified.

Fit and Sizing:

The cut is trim and follows the body for clean layering, and most women will find their standard size right.

Bottom Line:

Pull it on for cold resort laps, ski tours and winter hikes where you want warmth you can dial back. It suits women who want one baselayer top to cover most winter conditions.
