All-day base layer comfort built for movement in the Butter Up 1/2-Zip Top
What Our Gearhead® Experts Are Saying:
"I’ve worn this as a next-to-skin layer on long winter days, and the softness really stands out. It stretches easily under layers, manages moisture well, and the half zip is perfect for dumping heat without stopping."
We start cold mornings knowing comfort will matter hour after hour, and the Butter Up 1/2-Zip Top sets the tone from the first layer on. It feels smooth and forgiving against the skin, moving easily as we hike, travel, or settle into a long day outside without ever feeling restrictive.
The fabric breathes as our pace changes and wicks moisture before it becomes a distraction. With simple venting and a fit that layers cleanly, the Butter Up 1/2-Zip Top becomes the piece we forget we’re wearing—in the best possible way.
