Designed for all day use in mixed 3 season conditions, the Dyno LT Jacket is constructed from Granite Stretch, 4-way stretch, wind-resistant fabric with a PFC-free DWR for shedding light showers. The fabric's denier gradient construction regulates temperature and is ideal for multiple fast paced mountain activities including climbing and walking. You will appreciate the thermoregulatory properties of the material especially during active movement in the mountains and climbing. The jacket has a fully adjustable roll-up hood, with a reinforced hem with space for a climbing helmet and a two-way YKK VISLON main zipper with an internal protection leg, compatible with a climbing harness. Ergonomically sewn sleeves for easy movement. The jacket has two large side pockets with inner zipped mesh (also suitable for a map) and one outer zipped thimble pocket. Adjustable drawstring hem.
