When temps drop on trail or at camp, the Active Fleece Half Zip is our pick for women who want a no-fuss midlayer that pulls double duty. Merino-blend fleece naturally regulates temperature and fights odor without synthetic funk, so it stays fresh across back-to-back days. The half-zip lets you vent fast when the effort spikes.

• Merino-blend fleece construction regulates temperature naturally — warm when you're cold, not suffocating when you're not
• Built-in odor resistance outlasts synthetic fleece across multi-day trips without needing a wash
• Half-zip collar lets you dump heat on climbs without stopping to pull a full layer off
• Soft next-to-skin feel works as a standalone piece in mild conditions or under a shell when it gets serious
• Available in Black — clean, versatile, and works from the parking lot to camp without looking like a gear dump
