Capilene Thermal Crew Long Sleeve – Women's

Built for cold-weather output — trail runs, alpine approaches, and winter backcountry days — the Capilene Thermal Crew is our top pick for women who run hot but need real warmth. Polartec Power Grid fabric traps heat while venting hard when you push the pace, and HeiQ Pure odor control keeps it fresh across multi-day efforts.

• Polartec® Power Grid® fabric delivers a warm-to-weight ratio that outperforms traditional fleece base layers — the open grid next to skin traps heat without smothering you during high-output activity
• HeiQ® Pure odor control is built into the fabric, not a topical treatment — it holds up wash after wash and works well into multi-day trips without a resupply
• Raglan shoulder seams and underarm gussets eliminate the binding and chafing that kills a good trail day — the added spandex gives you unrestricted movement through full arm swings and dynamic terrain
• Smooth face construction layers cleanly under a shell or insulation without bunching, making it a true foundation piece for any cold-weather system — not just a standalone fleece
• Made in a Fair Trade Certified™ factory; available in multiple colorways including Night Plum/Obsidian Plum X-Dye — and the locker loop makes drying out between sessions actually happen
