The Kühl Wingman Primaloft lightweight synthetic insulated jacket uses 60g Primaloft One insulation and 100% Nylon fabric that has been waxed to help shed wind and water. The wax coating gives it a textured 3-D vintage effect as it fills in ridges and creases in the diamond shape quilting. Primaloft® One makes a great low bulk insulator with the benefits of being sandwiched behind a wind and water repellent nylon. It has approximately the right value of a 300 GSM fleece without the weight and bulk. Light and compressible, synthetic insulation like Primaloft will still keep you warm even when the fabric is damp. A built in stow-away hood is rolled up and fitted inside the collar and secured by two buttons so it can be easily accessed on the fly. The inside is lined with soft 100% Polyester fabric. Hand warming pockets feature a zippered closure. The left chest pocket has the classic button flap closure. Great as a layering piece, as a jacket in its own right at near freezing temps when you?re being active, and for around town --forgo that umbrella, The Kühl Wingman always has you covered.
