What Our Gearhead® Experts Are Saying:"This is my go-to base layer for mixed conditions—light enough for high-output days, but warm enough for early starts. I love the soft merino blend, and the half-zip is perfect for quick venting when I start to heat up."We reach for the Outdoor Research Alpine Onset 1/2-Zip Top when early mornings demand a little extra warmth but we know the day will heat up. Made with a soft blend of non-mulesed merino wool, polyester, and Lycra, this layer delivers the breathable insulation we need for skiing, hiking, or climbing—without ever feeling bulky or restrictive.
