Details from the website are: The Montane Featherlite Jacket is windproof, ultra lightweight, and highly breathable, so it is much more comfortable to wear than even the most breathable waterproof jacket which feels clammy and sweaty in comparison. Made from high quality Wind Barrier Dynamic high performance, durable, soft nylon fabric with four way stretch which is completely windproof so it stops the discomfort associated with a cool wind. Fast drying and with a Durable Water Repellent DWR finish, it will shed a light shower and maintain breathability in damp conditions. The stretch fabric, combined with careful tailoring enables easy, dynamic upper body movement whilst you are running. Weighing in at only 107 gms (3.8 oz) this is an impressive high performance jacket ideal for runners wishing to reduce wind chill whilst wanting to retain maximum breathability for the removal of body moisture. If your t-shirt gets soaked through when you run up that hill/mountain so you wonder wether it is worth bothering with a waterproof coat, then this is the jacket for you.
