Hot Days. Frosty Mornings. Cool Evenings. Chance of Rain. Chilling Winds.

Perfect Jacket.

What makes OSi Cool Jacket a cut above the rest? Designed to satisfy the discerning rider, OSi Cool Jackets are geared toward warm weather, but easily protect when the weather is a bit cool, a bit windy and even rainy with the ONLY full-sleeve, zip-out WATERPROOF/BREATHABLE/THERMAL liner on the market. Something you usually pay a lot more in a jacket. 

So why suffer a sweaty, rain-resistant, plastic bag of a liner when you can be comfortable and pay less
