Castelli Unlimited Merino Long Sleeve

Powerful trail jersey made from merino wool for colder days or as thermal protection in low temperatures.

Technical specifications:

• 41% merino wool (195 g/m²), 51% recycled polyester, and 8% elastane combine the warmth of wool with the moisture-wicking and durability of polyester
• Anatomically shaped, longer cut back designed for the typical riding position
• Neutral fit
• Front zippered valuables pocket made from microfiber material

This medium-weight Italian merino-polyester blend is perfect for cool autumn days, long stages, or as an insulation layer, thanks to its ideal mix of warmth and moisture-wicking properties. Wear it directly against the skin on chilly days to block cold winds, or with a long-sleeve base layer when it’s a bit colder. Paired with an Unlimited Puffy Vest, you’ll be well-equipped for late autumn. Worn under a jacket, it will keep you warm throughout the winter.

The jersey is also the top choice for long-distance or bikepacking tours, as it provides lasting warmth while benefiting from wool's natural ability to resist odors.

The material weight and open knit promote breathability, making it one of our cooler long-sleeve jerseys. However, its suitability for different layering options makes it an extremely versatile piece.

Since we designed it for layering with a vest and assuming you have pockets in your shorts and bike bags, this merino jersey does not include back pockets.
