Castelli Collapse Jersey

It keeps you warm while providing enough ventilation to prevent overheating. The inside is made of fluffy brushed fleece for warmth and comfort. The sleeves and sides feature additional stretch for a perfect snug fit.

The thermal jersey is the first step in cold-weather clothing, where Castelli has set the standard for high-performance apparel. We have continued this tradition here. You will wear this jersey on cool days, which is why we have equipped it with a fluffy brushed fleece back, while keeping the fabric stretchy to ensure a good fit. And since you will choose it when it’s not cold enough for a jacket, we designed the fabric to allow some airflow so you don’t overheat. We believe that a jersey like this should be highly functional. That’s why it has three spacious rear pockets, a silicone-coated anti-slip waistband, and a smooth YKK® Vislon® zipper.

Technical specifications:

• Warmer fabric on the torso
• Medium-weight warm X-Stretch on sleeves and sides for a great fit
• Anti-slip waistband
• 3 pockets on the back
• Smooth YKK® Vislon® zipper with a protective flap.
