The Polartec® 300 fleece fabric offers versatile thermoregulation that features lightness, breathability and fast drying. The outer face has the look of a sweater, while the interior has the classic look of the pile. Polartec® Thermal Pro® fabrics are the most dynamic in appearance and technically advanced among Polartec® insulation products. Available in a unique variety of patterns and textures with textures effects - much of which are designed to increase performance - these fabrics offer many options, virtually for all possible end uses. The new "high loft" versions have reached the highest heat / weight ratio ever offered by a Polartec® fabric. Other versions offer the same look of wool combined with all the essential performance of the fleece. Polartec® Thermal Pro® is the most unique fabric of the entire Polartec® family.
