What Our Gearhead(R) Experts Are Saying: "I've been using this fleece for shoulder-season hikes, and it's a great balance of warmth and breathability. The full zip makes it easy to adjust when the sun comes out, and I like how it transitions from trail to town without feeling like I'm still in my hiking kit." We reach for the ACG TF ADV Canwell Glacier Full-Zip Sweatshirt when we need warmth that moves as easily through the city as it does on a shoulder-season hike. Nike ACG gave this fleece a soft, brushed interior for lasting comfort and engineered it with versatility in mind-cozy enough for lounging, breathable enough for climbing switchbacks. The full-zip design lets us regulate body temperature on the go, while the universal cut and stylish finish mean we don't think twice about keeping it on after the trail. Whether we're packing for a cool-weather road trip or simply layering up for crisp mornings, this fleece earns a spot in the rotation.
