What Our Gearhead® Experts Are Saying: "I rely on the Sonebula Crewe for ski touring, winter running, and chilly bikepacking trips because it manages temperature and moisture better than almost anything else. The 200-weight merino stays warm when I’m still, breathes when I’m moving, and never gets that plasticky feel synthetics can."We pull on the Merino 200 Sonebula Long Sleeve Crewe when the day demands a layer that adapts seamlessly to cold starts, hard climbs, and shifting mountain weather. The 100% merino jersey fabric provides natural warmth and breathability, keeping us comfortable whether we’re kick-turning through fresh snow, loading up for a winter bikepacking loop, or hiking into cooler elevations. Because merino regulates temperature so effectively, this midweight top thrives as a technical baselayer or as a standalone piece on crisp shoulder-season days. Its moisture management and odor resistance shine on extended outings, while the soft feel ensures next-to-skin comfort during long missions. From backcountry laps to cool-weather travel, it’s a reliable partner across seasons and activity levels.
