Marmot's Essence jacket uses a durable stretch fabric to offer full waterproof protection and excellent breathable performance in a lightweight package.
Marmot says:
Mountain-tested by guides, this award-winning, super lightweight champ utilizes Marmot’s highly specialized, hyper breathable wind- and waterproof stretch fabric and a streamlined design to deliver ultimate protection ideal for ultra light hiking, adventure races and multi-pitch alpine climbs. Ultra lightweight with incredible stretch performance.
Marmot's Essence Jacket is a good balance of lightweight design and durable construction. The membrane technology provides a really good level of rain protection & breathability for a very reasonable price.
Marmot have kept the weight down by only having the most essential features, such as a single pocket on the chest & elasticated wrists. You can get the hood close to your head with two adjustable drawcords at the chin and with the velcro adjustment on the rear you can adjust the volume of the hood even further, allowing you to hunker down when the weather gets rough.
