Insulating Warmth for the Coldest Winter Rides — Merino Thermal LS Baselayer

Seasons can change in the blink of an eye. It's probably happened to you before — one minute it's a sweltering summer day where you're dying for a dip in the pool and then before you know it, you're dragging out the winter duvet because its freezing outside! If you factor in riding a bicycle as well, it can be difficult to know the perfect gear to wear to stay cool during the hotter days and warm during the colder ones. Luckily, PEARL iZUMi's Merino Thermal Long Sleeve Baselayer for men is here to save the day.

This heavy base layer measures up at an ultra-durable 250g/m2. It combines the 18.5-micron responsibly sourced Merino wool and eco-friendly recycled polyester technical fibers in a remarkable construction. This design positions polyester next to your skin for maximum wicking while the wool faces out for superior insulation. The nice long sleeves feature thumb loops that keeps the fabric from scrunching as you pull on your jersey, remaining comfortable no matter how long your ride.

Layer up and conquer the cold-weather seasons with the comfortable, professional fit that will allow you to break past your limits. With a phenomenal makeup of Merino wool and polyester created form recycled content, stay warm all winter long while still giving back to the environment. Embrace those cold-weather rides with the layer perfected to provide comfort no matter what.
