The DWR coating makes the fabric water repellent, so that water forms droplets on its surface and runs off instead of soaking in. This protects the fabric from getting wet quickly, providing greater comfort in wet conditions, but does not guarantee full water repellency.

The ultra-lightweight LiteAir carry system is based on a perforated foam panel and taut mesh that separates the back from the backpack, providing breathability and reducing pressure points. The entire system has been designed for maximum weight savings while maintaining stability and carrying comfort.
