Castelli Unlimited Thermal Jersey

The jacket, which is very warm yet extremely packable, is perfect for your adventures or multi-day tours. It features a windproof outer layer made of microfiber fabric with Polartec® Alpha® Direct insulation.

• Coated windproof microfiber fabric with DWR treatment
• Polartec® Alpha® Direct insulation for maximum loft with minimal volume
• Nano Flex stretch fabric at the lower sleeves, sides, and lower back provides additional elasticity and breathability
• Zippered pockets on the chest and back
• Two large back pockets covered with a flap to look good even off the bike
• YKK® Vislon® zipper with a U-shaped pull
• Woven inner label and vintage scorpion logo on the sleeve

When the challenge lies more in distance than speed, this jacket combines warmth and comfort with a style that looks great both on the bike and during coffee stops.

We are increasingly undertaking long adventure tours. Sometimes this involves overcoming significant elevation changes or riding through the cold of night and the heat of day. Then it’s multi-day bikepacking trips. This jacket shines in such situations because it provides plenty of insulation and warmth when needed, but can be packed small into your saddlebag when not in use.

The outer layer is a material you may have seen in some high-end down jackets from major brands. We like it because it is so lightweight while still keeping the wind out. The inside is made of Polartec® Alpha® Direct, the lightest, most packable, and moisture-wicking insulation on the market. It warms like synthetic down but doesn’t require an inner layer that would restrict breathability and add weight.

For your next unlimited adventure, simply pack this jacket and a GORE-TEX Idro jacket in your bag, and you’ll be ready for anything.
