With a full set of technical features and using a unique combination of tough, super lightweight Pertex Quantum CS-10 fabric in the main body and breathable Hypervent panels across the back and under the arms, the Montane Men's Featherlite Pro Pull-On protects from the wind while offering breathable comfort in key areas.Pertex Quantum CS-10 fabric uses unique diamond shaped nylon yarns, making it exceptionally tough for its 37g/m² weight. An optimum thread count creates a fabric which has an increased resistance to snagging and abrasion. Ideal for areas where wind protection and abrasion resistance are needed. A durable water repellency helps shed light rain. Air permeable nylon Hypervent fabric used across the back and under the arms to allow heat and moisture to escape. Technical tailoring around the arms prevents the lower hem lifting while you reach high. The fully windproof climbing helmet-compatible hood with wired peak rolls away and zips into the collar when not in use. A YKK reverse coil zipped chest pocket is designed to fit a GPS or mobile phone securely while the ergonomic lightweight zip pullers make use easier when wearing gloves.
