The Norrøna /29 pureUll Neck moves easily between a skin track, a hiking trail, and a walk across town. A single-knit 100% merino wool construction at 180 grams per square meter keeps the fabric light enough for everyday wear while still regulating temperature and resisting odor on longer outdoor days. That balance is what lets one neck gaiter cover both a technical outing and a casual one without swapping pieces. What Our Gearhead® Experts Are Saying:"I leave mine on after I finish skinning, since it doesn't trap heat once I stop moving and still looks normal enough to wear into town."
