Equipped to tackle cold-weather, sweat-producing activities like skiing, climbing or trail running, the Marmot Isotherm Jacket offers warmth, wind-resistance, and moisture-wicking properties.
Equipped to tackle cold-weather, sweat-producing activities like climbing, the Marmot Men’s Isotherm Jacket offers the combined heat saving and moisture wicking power of Polartec Alpha insulation sheathed in a durable, lightweight wind-resistant 20D Pertex Quantum face fabric. Reinforced softshell construction in the shoulders and sleeves adds an extra level of weather protection where it is needed most, while the DriClime mesh lining lends breathability.
The Isotherm Jacket provides confidence through the full range of upper body movement thanks to Marmot’s Angel-Wing construction preventing ride up at the waist. A zip chest pocket, two zip hand pockets, and an interior mesh pocket safely store small essential items near at hand. Elastic bound cuffs and an elastic draw cord hem help to seal out windy gusts and snow. The regular fit allows you to easily wear light base layers underneath and weatherproof outer shells over the Isotherm Jacket.
