The EPS Knit Liner for men has been designed to transition your summer helmet into the cold winter months. It features audio drop-in ear pockets so you can easily insert chips, and a BOA® dial for adjustment to achieve the best fit. Included with the purchase of this winter knit liner is a goggle clip that is securely screwed on to keep your goggles firmly attached to the helmet. This product is not compatible with the new Macon 2.0.
