Intraknit Thermal Merino Baselayer Hoodie - Women's

What Our Gearhead® Experts Are Saying:

"This hoodie is my go-to for cold, high-output adventures. The mapped merino blend keeps me warm where I need it and ventilated where I don’t overheat. It fits snug under a shell, the hood layers great under a helmet, and the thumbholes seal everything in. Perfect for ski touring or fast-paced hikes."

When we’re pushing the pace on cold alpine starts, we trust the Intraknit Thermal Merino Base Layer Hoodie to keep us moving comfortably. Smartwool built this technical layer with performance-driven merino wool blended with synthetic fibers to balance warmth, stretch, and moisture control. The form-fitting silhouette moves like a second skin, while mesh-knit zones offer targeted ventilation to prevent overheating mid-climb.

We love the ergonomic 3D mapping that provides a custom-feeling fit and seamless support through intense activity. The integrated hood and high collar seal in warmth when winds pick up, and the thumbholes lock sleeves in place for easy layering. Whether we’re chasing first tracks or leading steep skintracks, this base layer keeps us primed for performance.
