Women's Glacial™ IV Fleece Half-Zip Pullover

The Women's Glacial™ IV Fleece Half-Zip Pullover is Columbia's go-to midlayer: 100% polyester microfleece that provides genuine warmth at a weight light enough to pack and carry rather than bundle. The half-zip gives you the warmth retention of a closed neckline with the option to open it when your body temperature catches up.

• 100% polyester microfleece — the micro-weight fleece insulates effectively without the bulk of a full-loft midlayer; Columbia's Glacial series has been refined across four generations for exactly this warmth-to-weight balance.
• Half-zip construction — zip opens to mid-chest for ventilation on the move; fully closed traps warmth efficiently for stationary use or cold conditions.
• Lightweight packable construction — folds to a compact bundle; the polyester doesn't hold moisture, so it dries fast if caught in light rain.
• Relaxed everyday silhouette — works as a standalone layer for cool weather or as a midlayer under a shell jacket for outdoor activities.
• Machine washable — cold wash, tumble dry low; polyester microfleece holds its structure and loft through regular washing without pilling excessively.

Fits true to size in a relaxed fit. Columbia sizing is consistent and generous; if you plan to layer over a heavier base layer in cold conditions, stay with your usual size. The half-zip neck accommodates high collars underneath without pinching. Pairs cleanly with outdoor trousers or casual jeans.
