Built to take you outside in any weather, the Kari Traa Tirill Women's Thermal Pants pair a brushed fleece interior with a wind- and water-resistant face. The thick, warm fabric repels wind and light moisture while keeping you cozy from the inside, making it a hardworking cold-weather base layer. They are the go-to thermal legging for the most exposed winter days.

Why we like it:

The wind- and water-resistant face is what sets these apart from a standard base layer; they repel the elements while a brushed fleece interior keeps you warm. It is a thermal legging that handles weather most base layers cannot.

Features and Functions:

The Tirill Thermal Pants pair a polyester and recycled-polyester main fabric with recycled-polyester and polyamide contrast panels, finished with a brushed fleece interior and a wind- and water-resistant face. The thick, warm construction provides insulation and weather resistance as a technical base layer.

Fit and Sizing:

A close, supportive fit layers under ski pants or wears on its own for low-key days. True to size, with stretch for movement.

Bottom Line:

As a weather-resistant thermal base layer for cold, exposed days, the Tirill Pants are best at warm, wind-blocking comfort under your layers or on their own. A hardworking legging for deep winter.
