Peter Storm Women's Long Sleeve Thermal Zip Neck Baselayer Top - Black - Size 18

Its primary purpose is to provide thermal insulation and help regulate body temperature during active pursuits in cold weather.

It is best suited for activities like fitness, walking, hiking, and other outdoor or active pursuits in cool to cold conditions.

Refer to the brand's sizing chart or consult product measurements if available. Given it's a close-fit garment, accurate sizing is important for comfort and performance.

While it can be worn on its own in milder cool conditions, it is designed primarily as a base layer to be worn under other clothing for optimal warmth and performance.

The fabric is a blend of 65% polyester and 35% viscose, designed for thermal insulation and comfort.

The zip neck allows for adjustable ventilation. You can zip it down to increase airflow and cool down, or zip it up for extra warmth and protection.

For very extreme cold, it functions best as part of a layering system, worn over or under other appropriate garments.

Ensure the baselayer is a snug fit and worn directly against the skin. For colder conditions, consider adding an insulating mid-layer and a windproof outer layer.

Avoid using fabric softeners. If stiffness persists, re-wash with a small amount of mild detergent on a gentle cycle and air dry.

Gently pull the zip. If it's stuck on fabric, carefully maneuver the material away. If persistent, apply a small amount of graphite (from a pencil lead) to the zip teeth.
