Clothing Baselayers - Mens

Pearl Izumi Merino Long Sleeve Baselayer

Smart textile design with sustainable principles exemplify Pearl Izumi's Merino wool baselayers. The Merino Long Sleeve Baselayer is the standard weight option for three-season layering. This highly technical base layer delivers true sustainable performance thanks to it's Transfer Merino fabric, combines wool and recycled polyester in a unique plated fabric construction that places polyester next to the skin and fine 18.5-micron merino wool on the exterior for superior moisture transfer and thermal regulation. By putting polyester next to the rider’s skin, it transports moisture away to the Merino layer where it can evaporate even as the wool acts as insulation. Smart.

As a natural fiber, merino wool is renewable sustainable resource with it's orgnanic technical properties. The recycled Repreve® XS Polyester technical fibers are made from recycled plastic water bottles, which at least maximizes and extends the life cycle of the plastic. The Wool Blend Performance is certified by the Woolmark Company to ensure the highest quality product.

The form fit construction is built for an anatomic cycling position, and the small finish details are not insignificant. The base layer uses a set-in sleeve design for a versatile form-following fit to make layering cleaner and easier. The stitching is clean and soft against the skin, and the hem, cuffs, and neckline have a simple, low volume folded design that will ensure use and cleaning care as well as being comfortable- not noticeable. When the weather turns cool and damp nothing beats the performance a great baselayer, and the Pearl Izumi Merino Long Sleeve is one of the best.
