White Collection

The Go Jacket is Castelli's most versatile jacket. It can be used as a light shell in mild conditions or go to cold conditions by adding insulating layers underneath. Stretchy, comfortable, breathable, windproof, water resistant, elegant, and lightweight, this jacket has it all. Get out and Go.

Our lightest and most packable wind shell that fits close to body with a stretch breathable back. It effectively blocks wind on the front without causing overheating.

For those days when most people ride the trainer. We use a fleece-lined GORE-TEX INFINIUM™ WINDSTOPPER® outer layer with a full Polartec® Power Stretch® inner layer to make our warmest bootie ever.
