What Our Gearhead® Experts Are Saying: "I’ve worn the Fay Midweight Merino Top on everything from cold skintracks to casual winter days, and it always hits the sweet spot. The merino blend keeps me warm without overheating, and I love how it naturally resists odor. It’s soft enough for all-day wear but technical enough to be my go-to baselayer."When the temps drop, we reach for the Fay Midweight Merino Top to keep us warm, dry, and comfortable through long days outside. Halfdays crafted this versatile baselayer with a thoughtful blend of merino wool and viscose, giving us the best of both worlds—thermoregulating warmth and next-to-skin softness.

Whether we’re skiing, hiking, or lounging at camp, the Fay Midweight Merino Top is a staple in our cold-weather kit.
