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 perfectly suited for cool autumn days, long stages, or as an insulation layer, thanks to its ideal mix of warmth and moisture management. Wear it directly against your skin on chilly days to block out 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. And worn under a jacket, it will keep you warm throughout the winter.

The jersey is also the first 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 the looser 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 to be combined with a vest and assuming you have pockets on your shorts and bike bags, this merino jersey does not include back pockets.
