Páramo is different - you'll find you can cut down on the layers you carry because the jacket fulfils more functions. Páramo jackets also vent more effectively than many other garments. Páramo is designed to be worn not carried and many Páramo wearers simply wear their Páramo jacket next to the skin - it's a soft fabric, not at all like wearing a membrane. If you've got time have a look on the OM gear reviews or read some of the forum discussions on Páramo, or talk to someone who wears Páramo and what they think. We do have a very loyal following - with good reason!
