What Our Gearhead(R) Experts Are Saying:"I keep this neck tube in my pack year-round because it weighs nothing and adds a ton of comfort when the wind picks up. The stretch fleece feels soft against the skin, and it breathes well enough that I don't overheat on steep climbs. It's the kind of piece you forget about until you really need it."We reach for the Transition Neck Tube when winter air turns sharp and we want reliable warmth without slowing down. The Thermic(TM) Stretch fleece feels soft the moment it meets our skin, and its breathable construction keeps us comfortable as we push hard up cold gullies or weave through forested trails. Easy to stash in a pocket and quick to pull on when the wind rises, it delivers instant protection during fast-paced mountain ascents. As conditions shift, the tube's flexible design adapts with us. Its smooth stretch offers a secure, comfortable fit whether we're pairing it with a shell, a midlayer, or a simple base top. The lightweight fabric dries quickly and adds warmth without bulk, making it a small but essential layer for unpredictable winter outings.
