Classic Thermal Merino 1/4 Zip Base Layer – Kids'

For cold-weather hikes, ski days, and chilly morning trail time, this midweight merino 1/4 zip is our top pick for keeping kids warm without the bulk. Merino wool regulates temperature naturally and fights odor through long days out, while the zip neck lets them dial ventilation on the fly. Works solo on mild days or as a reliable base under a shell when it gets serious.

• Midweight merino wool construction delivers natural warmth and breathability without synthetic bulk or post-day funk
• 1/4 zip neck allows quick ventilation adjustments from cold starts to hard uphill efforts — no stopping to layer up or down
• Merino fibers wick moisture away from skin and dry faster than cotton, keeping kids comfortable when conditions change
• Versatile enough to wear as a standalone layer on mild days or tucked under a shell when temperatures drop
• Available in Charcoal Heather, Nival Blue Heather, Indigo Linear Peaks, and Lavender Sky Heather — sizes XXS through XL
