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 tailored 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 rides, 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 prepared well into 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 odor-resistant properties.

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

Since we designed it for layering with a vest and assuming you have pockets on your shorts and bike bags, we have omitted rear pockets on this merino jersey.
