Obermeyer Oly Men's Baselayer Zip Top

The Obermeyer Oly Men's Baselayer Zip Top is a stretchy, brushed base layer made to sit next to the skin and manage moisture all day. It adds a touch of warmth without bulk and vents through a zip neck when you start working. It is the dependable foundation that keeps your whole layering system performing.

Why we like it:

The brushed-back fabric is the comfort detail; it feels soft and warm against the skin while still wicking sweat on the climb. The zip neck makes temperature control effortless.

Features and Functions:

The Oly top is made from an 81 percent polyester, 19 percent elastane blend with a brushed back and a DWR finish, engineered to wick moisture and stretch with movement. A zip neck lets you vent heat fast, making it an easy-to-manage base layer for active cold-weather days.

Fit and Sizing:

A performance fit hugs close to the skin for efficient warmth and moisture transfer. True to size, made to layer invisibly under everything.

Bottom Line:

As the base of a layering system, the Oly is best at moisture-wicking warmth beneath a midlayer and shell. A comfortable, stretchy foundation for skiing and winter activity.
