Hot Days. Frosty Mornings. Cool Evenings. Perhaps Rain. Chilly Winds. Perfect Jacket.

What makes AN OSi Cool Jacket different? Like similar jackets OSi Cool Jackets are geared toward warm weather, but that is where the similarity ends. When the weather turns cool, windy or even rainy the Cool Jacket's exclusive WATERPROOF/BREATHABLE/WINDPROOF THERMAL (removable) liner keeps you riding without changing jackets.
