This men’s insulated vest employs Primaloft Gold Eco and the protection of a 100% recycled polyester shell to make it warm enough for a cool day while keeping the bulk to a minimum. We added a durable water repellent (DWR) finish to shrug off misty mornings and light precipitation. A special back pocket is cut from mesh so a cell phone can be put in flash mode and used as a blinky for increased visibility at night, and should you have a dedicated light, you can clip it to the reflective utility loop placed on the low back.
