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 – made in Italy – is perfectly suited for cool autumn days, long rides, or as an insulation layer, thanks to its ideal mix of warmth and moisture management. Wear it directly on your 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. And worn under a jacket, it will keep you comfortable throughout the winter.

The jersey is also a top choice for long-distance or bikepacking tours, as it provides lasting warmth while benefiting from the natural odor-resistant properties of wool.

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 to be combined with a vest and assuming you have pockets on your shorts and bags on your bike, we have omitted rear pockets on this merino jersey.
