Castelli Phase Jersey

It keeps you warm while providing enough ventilation to prevent overheating. The inside is made of soft 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 apparel, where Castelli has set the standard for high-performance clothing. We have continued this tradition here. You will wear this jersey on cool days, which is why we have equipped it with a soft brushed fleece back, while the fabric remains 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 a jersey like this should be highly functional. That’s why it has three spacious rear pockets, a silicone-coated gripper elastic at the hem, and a smooth YKK® Vislon® zipper.

Technical specifications:

• Warmer fabric on the torso
• Mid-weight Warm X-Stretch on sleeves and sides for a great fit
• Anti-slip gripper elastic at the waist
• 3 pockets on the back
• Smooth YKK® Vislon® zipper with a zipper guard.
