The August Pant combines performance and protection. This pant features our DRYPLAY 10K/10K PFC-free membrane for unmatched waterproof-breathability, a Teflon EcoElite™ PFC-free durable water repellent treatment, Thermal STD 80-gram insulation for extra warmth, and critically taped seams to keep moisture out. And to be able to wear it as long as possible, it features our GROW WITH ME system to lengthen the gaiters and lower pant leg when that growth spurt hits much earlier than expected!
