Classic All-Season Merino Base Layer 1/4 Zip – Women's

For women who push hard in variable conditions — early morning trail runs, cool-weather hunts, multi-day trips — this quarter-zip is a first layer that earns its place year-round. Merino wool regulates temperature naturally and resists odor without chemical treatments, so it keeps working whether you're grinding uphill or standing still in a deer stand. The quarter-zip collar lets you manage ventilation without breaking stride.

• Merino wool construction regulates body temperature in both heat and cold — genuinely useful in the South where mornings and afternoons feel like different seasons
• Natural odor resistance lets you wear it multiple days between washes, making it the right call for multi-day backpacking trips or back-to-back hunt days
• Quarter-zip collar gives you fast ventilation control when effort spikes on the trail or in the field — no need to stop and strip a layer
• Fitted base layer cut sits close to the skin for efficient moisture transfer and clean layering under a shell, vest, or mid-layer without bunching
• Available in standard sizes (XS–XL) and extended plus sizes (1X–3X) so more athletes get a fit that actually functions as a base layer should
