Janji's Ms Thermalrunner insulated jacket offers winter protection without the bulk. It employs targeted insulation to maximize warmth where it matters most. Crafted with hyperlight, durable nylon, the shell resists water and blocks wind, readying one for unpredictable trails. The jacket conveniently stows into its chest pocket for effortless packability. With a bungee hem for an adjustable fit and signature reflective logos, it ensures visibility in low light conditions.
