AlpineCrest - Unisex Thermolite® Air-Fleece Thermal Hooded Sweatshirt

Material: 100% Tech Polyester

Designed for lightweight warmth and everyday comfort, this Thermolite® hooded sweatshirt features hollow-fiber insulation that helps retain heat while allowing moisture vapor to escape. Made from 100% polyester, it is breathable, quick-drying, wrinkle-resistant, shrink-resistant, and finished with a modern color-block design.

Thermolite® Hollow-Fiber Thermal Technology – The air-fiber construction is inspired by the insulating properties of polar bear fur, using hollow fibers to create spaces that trap still air within the fabric. This helps retain body warmth while maintaining a lightweight and comfortable feel.

Lightweight Warmth Without the Bulk – The hollow-fiber structure provides an insulating layer without relying on heavy fabric. It delivers comfortable warmth while keeping the sweatshirt light and easy to wear for outdoor activities and everyday layering.

Moisture-Wicking & Quick-Dry Performance – The breathable fiber construction helps move moisture vapor away from the body and allows it to evaporate efficiently. This helps maintain a drier, more comfortable feel during active movement.

Highly Breathable Comfort – The air-fiber structure allows airflow and moisture vapor to move through the fabric, helping reduce stuffiness. It is designed to balance warmth with ventilation during changing activity levels.

Temperature-Regulating Comfort – The insulating air spaces help retain warmth when temperatures drop while the breathable construction helps release excess heat during movement. This creates a more balanced wearing experience across changing outdoor conditions.

Helps Block Cold Air – The thermal fabric construction creates an insulating barrier between the body and outside air, helping reduce the impact of cool airflow. It's well suited to fall outdoor activities and early-winter layering.

Soft Air-Fiber Texture – The fabric has a soft, lightweight texture that feels comfortable against the skin while maintaining a warm, insulated hand feel. Its smooth construction makes it easy to wear throughout the day.
