Natural Merino Wool Blend Materials for Breathable, Odor-Resistant Warmth

Designed for active use in cool and cold conditions, the Outdoor Research Alpine Onset Merino 150 Beanie combines lightweight warmth, excellent moisture management, and a low-profile fit that integrates easily into a cold-weather layering system.

Constructed from a technical merino wool blend, the Alpine Onset Merino 150 Beanie provides natural temperature regulation and odor resistance while efficiently wicking moisture away from the skin. The fabric is highly breathable and dries quickly, making it well suited for high-output activities and extended wear.

Its close-to-head, low-profile construction allows the beanie to fit comfortably beneath helmets and hoods without creating unnecessary bulk, making it an excellent option for military field use, skiing, climbing, hiking, and other cold-weather activities.

A double-layered ear band adds extra insulation around the ears and forehead, providing additional warmth where it is needed most while keeping the remainder of the beanie lightweight and breathable.

The merino blend also provides UPF 30 sun protection, adding useful protection during prolonged outdoor exposure.

Lightweight, packable, and versatile, the Alpine Onset Merino 150 Beanie works equally well as a standalone lightweight toque or as part of a layered cold-weather system.
