Castelli Unlimited Thermal Jersey

The jacket that is very warm yet extremely packable – 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 underside of the sleeves, sides, and lower back provides additional elasticity and breathability. Zippered pockets on the chest and back. Two large rear pockets covered with a flap for a stylish look 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 taking long adventure trips. Sometimes that involves overcoming significant elevation changes. Or rides through the cold of night and the heat of day. Then there are multi-day bikepacking trips. This jacket excels in such situations because it offers plenty of insulation and warmth when you need it, yet packs down small in your saddlebag when you don’t. The outer layer is a material you’ve seen in some high-end down jackets from major brands. We like it because it’s 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, just pack this jacket and a GORE-TEX Idro jacket in your bag, and you’ll be ready for anything.
