What Our Gearhead® Experts Are Saying: "I like this beanie for cold starts and technical days when a full hat would be too much. It fits cleanly under a helmet, adds just enough warmth, and doesn’t get clammy when I’m moving. The merino blend really helps it stay fresh after long days." We pull on the Overlook Merino Wool Liner Beanie when cold air meets high-output movement. Patagonia designed this low-profile beanie to deliver lightweight warmth without bulk, making it ideal for layering under helmets or wearing solo during cool-weather adventures. It’s the kind of piece that quietly does its job and never gets in the way. The merino wool blend naturally regulates temperature, keeping us warm when it’s chilly while still breathing as effort ramps up. Moisture-wicking performance helps manage sweat, and the naturally odor-resistant fibers keep it feeling fresh through repeated use. Simple, packable, and easy to forget you’re even wearing it, this liner beanie is a cold-weather essential we keep close.
