Materials - TNF™ APEX Fabrics

A soft shell technology breakthrough. Apex is a signature material, researched and developed exclusively by The North Face. Apex makes the fleece/shell combination possible through its proprietary blend of characteristics. Apex offers the dynamic duo of a tightly woven abrasion-phobic face for protection, and a soft-brushed interior for performance and comfort. Apex technology is built to stretch for comfort and mobility and is treated with our Durable Water Resistant (DWR) finish.

Apex features are nylon constructed and woven for stretch enhancement to achieve the balance between weather resistance and breathability. The average air permeability rating for these fabrics is below 20 CFM.

Apex is finished with DWR to increase water shed. DWR is laboratory tested for durability and extended wash and wear according to the standard AATCC 22 Water Repellency Spray Test. All Apex™ fabrics meet The North Face standard rating of 90 (70 after a specified number of home washings) for long-term durability.)

All Apex garments keep you dry in a thick fog or light rain environment. Apex garments are built for warmth. The tightly woven fabric face creates a hard barrier to the elements of cold weather, while the soft-brushed interior allows for a soft warm-next-to-skin feel. The brushed interior also promotes a microclimate, allowing for superior moisture management and continued climate control.

TNF™ Apex Aerobic
TNF™ Apex Aerobic fabric denotes the lightest weight and most breathable of Apex garments. It offers the greatest stretch and mobility, with a CFM of 10+, making it ideal for running, cycling, and other highly mobile, aerobic activities.
Wind Resistance: 10+ CFM
Weight Range: 4 - 7 oz.
Usage: High levels of extended aerobic activity (running, biking, climbing) in mild winter and spring conditions.

TNF™ Apex Universal
TNF™ Apex Universal is the most versatile of the Apex fabrics. With enhanced stretch and a CFM between 5 and 15, it is both breathable and water resistant, making it ideal for a wide range of activities and weather conditions.
Wind Resistance: 5 - 15 CFM
Weight Range: 8 - 11 oz.
Usage: Medium levels of aerobic activity (hiking, biking, climbing, skiing, snowboarding) in moderate winter conditions.

TNF™ Apex ClimateBlock Fabric
Apex ClimateBlock is the most protective Apex fabric. Virtually waterproof and windproof, the fabric also maintains a comfortable level of breathability. Apex ClimateBlock is ideal for trekking, skiing, and snowshoeing in challenging, inclement weather conditions.
Wind Resistance: 0 CFM
Weight Range: 11 - 14 oz.
Usage: Mild levles of aerobic activity (hiking, skiing, snowboarding) or for use in more severe winter conditions.
