Premium down warmth in a technical package defines the Kari Traa Tirill Women's Thermal Jacket. Real down insulation keeps you warm even in the coldest conditions, while wind-resistant panels protect the most exposed areas. It is the warm, technical midlayer for women who chase winter at its harshest.

Why we like it:

The down-and-wind-resistant combination is the smart part; lofty down warms the core while wind-resistant material shields the exposed zones where heat escapes fastest. It is more technical than a typical down sweater.

Features and Functions:

The Tirill Thermal Jacket is insulated with premium 60/40 down at a 400 to 450 fill power, wrapped in a down-proof fabric with wind-resistant material on the exposed areas. The combination delivers lofty warmth with targeted weather protection.

Fit and Sizing:

A regular fit sits over a base layer and under a shell. True to size, with room for the down to loft.

Bottom Line:

As a warm midlayer or a standalone insulator, the Tirill Thermal Jacket is best at down warmth with technical wind protection. A cozy, capable layer for the coldest days.
