Pearl Izumi Men's Merino Long Sleeve Baselayer
$90.00
This highly technical base layer delivers true sustainable performance. The key to staying comfortable on cold days is staying dry.

The base layer uses a set-in sleeve design for a versatile form-following fit to make layering easy. - Transfer Merino fabric combines wool and recycled polyester for sustainable technical performance. - Unique plated fabric construction places polyester next to skin and merino on the exterior for superior moisture transfer and thermal regulation. - Made using fine 18.5-micron merino wool for superior comfort. - Recycled Repreve XS Polyester technical fibers are made from recycled plastic water bottles. - Set in sleeve construction for easy layering and versatility. - Wool Blend Performance certified by the Woolmark Company to ensure the highest quality product.
