When speed, weight and packability matter most, the Superalloy Bio Rain Jacket delivers reliable waterproof protection without weighing you down. Designed for trail runners, fast hikers and anyone who wants an emergency shell that's always within reach, it packs into its own pocket and weighs just 155g. Its ultralight construction also makes it an excellent option for many trail running events that require competitors to carry a waterproof jacket as part of their mandatory gear.*
Built with Marmot's NanoPro™ waterproof technology and an ultralight bio-based ripstop fabric, the Superalloy provides waterproof, windproof and breathable protection while taking up minimal space in your running vest, daypack or travel bag. Whether you're chasing a weather window on the trail, travelling light or preparing for unpredictable conditions, it's the jacket you'll be glad you packed.
Its minimalist design doesn't compromise on performance. Fully taped seams, an adjustable hood, water-resistant front zip and a chest pocket that remains accessible while wearing a running vest or backpack provide the protection you need without unnecessary bulk.
