Castelli Fly Direct Jacket

Easily packable, lightweight thermal jacket, perfect for longer cycling adventures or as an extra layer in fluctuating temperatures. This warm winter jacket features a lightweight FLY design and Polartec® Alpha® Direct insulation, making it compact and suitable for various conditions and long bike rides.

The Fly Direct Jacket combines an extremely lightweight design with Polartec® Alpha® Direct insulation in a jacket that keeps you exceptionally warm. Its lightweight construction allows for quick packing into a pocket or frame bag when temperatures change. The design of this jacket is based on an ultra-lightweight windproof layer, which is treated with a DWR finish for riding on wet roads or during short rain showers. Next, we added Polartec® Alpha® Direct insulation to this layer, which is incredibly warm and breathable despite its low weight. The front features a YKK® Vislon® two-way zipper that opens easily for comfortable temperature regulation as training intensity increases. On the back, there are three pockets providing ample storage for essentials on the go. Reflectors on the waist and sleeve cuffs enhance visibility. Together, these features make the Fly Direct Jacket the top choice among winter jackets when it comes to weight, warmth, and easy packability.
