CASTELLI MIRACOLO WOOL LS BASE LAYER

"What is that?" was the #1 question lighting up Castelli's socials when Tao Geoghegan Hart wore a prototype of this base layer up and over the Stelvio on his way to winning the 2020 Giro d'Italia. Those conditions highlight where the Miracolo Wool Long Sleeve base layer excels: it provides a surprising amount of warmth by pulling moisture away from the body, keeping you warm always, but the mesh construction means it's not too hot. Great under a jersey for high intensity, or for layering under a jacket.

• Merino wool mesh mixed with nylon for strength and elastane for stretch
• Minimalist finishing at collar, wrist, and waist for minimal bulk
• Raglan sleeve to avoid seam on shoulder under bib strap
• Woven scorpion logo label at side collar
• Temperature range: 4°C - 15°C / 39°F - 59°F
