Isotherm Insulated Jacket - Men's

The Marmot Men's Isotherm Insulated Jacket keeps you warm, dry, and, most importantly, ready for action when you take it into the mountains for some hiking or climbing (or both). A combination of ultralight ripstop fabric, softshell panels, and low-profile insulation allows you to climb comfortably while still keeping you warm while you're belaying.

Polartec's Alpha insulation is the U.S. Special Forces' go-to insulation for dynamic missions, so you know you can rely on its warmth when you're summiting. Softshell panels give the shoulders and sleeves excellent breathability and a four-way stretch for uninhibited mobility, while the Pertex Quantum shell provides windproof protection in an ultralight fashion. Angel-Wing Movement ensures freedom of movement when you're reaching for the anchors.
